Congratulations on your new bike

purchase and welcome to the

Nukeproof family!

We hope you enjoy the ride. This is an

introductory manual for your bike, please

visit www.nukeproof.com technical pages for

any further literature. If you have any further

queries not covered in our manuals, please

consult with your Authorised Nukeproof Dealer.

NOTE

This manual is not intended as a

comprehensive assembly, use, service, repair,

or maintenance manual. Please consult with

your Authorised Nukeproof Dealer for all

assembly, service, repairs, or maintenance.

Your Authorised Nukeproof Dealer may also be

able to refer you to classes, clinics or books on

bicycle use, service, repair, or maintenance.

IMPORTANT

This manual contains important safety,

performance, and service information. Read

it before you take the rst ride on your new

bicycle and keep it for reference. Additional

safety, performance, and service information

for specic components such as pedals, or

for accessories such as helmets or lights that

you purchase, may also be available from your

dealer.

Ensure your Authorised Nukeproof Dealer has

given you all the manufacturers literature that

was included with your bicycle or accessories.

If you have any questions or do not understand

something, take responsibility for your safety,

and consult with your Authorised Nukeproof

Dealer as a rst point of contact.

GENERAL WARNING

Like any sport, cycling involves risk of injury

and damage. By choosing to ride a bicycle,

you assume the responsibility for that risk,

so you need to know - and to practice - the

rules of safe and responsible riding and of

proper use and maintenance. Proper use and

maintenance of your bicycle reduces risk of

injury. This manual contains many “warnings”

and “cautions” concerning the consequences

of failure to maintain or inspect your bicycle

and of failure to follow safe cycling practices.

• The combination of the safety

alert symbol (!) and the

word “warning” indicates a

potentially hazardous situation

which, if not avoided, could

result in serious injury or

death.

• The combination of the safety

alert symbol (!) and the

word “caution” indicates a

potentially hazardous situation

which, if not avoided, may

result in minor or moderate

injury, or is an alert against

unsafe practices.

• The word “caution” used

without the safety alert symbol

(!) indicates a situation which,

if not voided, could result in

serious damage to the bicycle

or the voiding of your warranty.

• Many of the warnings and

cautions say, “you may lose

control and fall”, because

any fall can result in serious

injury or even death, we do

not always repeat the warning

of possible injury or death.

Because it is impossible to

anticipate every situation or

condition which can occur

while riding, this manual

makes no representation

ENJOY THE RIDECONTENTS

1.A. BIKE FIT

1.A.1. Is your bike the right size? To check,

see Section 3.A. If your bicycle is too large or

too small for you, you may lose control and fall.

If your new bike is not the right size, ask your

Authorised Nukeproof Dealer to exchange it

before you ride it.

1.A.2. Is the saddle at the right height? To

check, see Section 3.B. if you adjust your

saddle height, follow the minimum insertion

instructions in Section 3.B.

1.A.3. Are saddle and seatpost securely

clamped? A correctly tightened saddle will

allow no saddle movement in any direction.

See Section 3.B.

1.A.4. Are the stem and handlebars at the right

height for you? If not, see Section 3.C.

1.A.5. Can you comfortably operate the

brakes? If not, you may be able to adjust

their angle and reach. See Section 3.D. and

Section 3.E.

1.A.6. Do you fully understand how to operate

your new bicycle? If not, before your rst

ride, have your Authorised Nukeproof Dealer

explain any functions or features which you do

not understand.

1.B. SAFETY FIRST

1.B.1. Always wear an approved helmet

when riding your bike, and follow the helmet

manufacturer’s instructions for t, use and

care. If a helmet is damaged, do not use and

replace immediately.

1.B.2. Do you have all the other required

and recommended safety equipment? (See

Section 2 - Safety). It’s your responsibility

to familiarize yourself with the laws of the

areas where you ride, and to comply with all

applicable laws.

1.B.3. Do you know how to correctly operate

your wheel quick release? Check Section

4.B.1. to make sure. Riding with an improperly

adjusted wheel quick release can cause the

wheel to wobble or disengage from the bicycle

and cause serious injury or death.

1.B.4. If your bike has toe clips and straps or

clipless “step-in” pedals, make sure you know

how they work (see Section 4.E.). These

pedals require special techniques and skills.

Follow the pedal manufacturer’s instructions

for use, adjustment, and care.

1.B.5. Do you have “toe overlap”? On smaller

framed bicycles your toe or toe clip may be

able to contact the front wheel when a pedal

is all the way forward and the wheel is turned.

Read Section 4.E. to check whether you have

toe overlap.

1.C. MECHANICAL SAFETY CHECK

Routinely check the condition of your

Nukeproof bicycle before every ride. Nuts,

bolts, screws, and other fasteners: because

manufacturers use a wide variety of fastener

sizes and shapes made in a variety of

materials, often differing by model and

component, it is not possible for this manual

to specify correct torque (tightening force)

for each specic fastener on your Nukeproof

bicycle.

We can tell you the importance of correct

torque, but not the specic torque required for

each fastener on your bicycle (see Section

4.G.). To correctly torque a fastener, a torque

wrench must be used. A professional bicycle

mechanic with a torque wrench should torque

the fasteners on your bicycle. If you choose to

work on your own Nukeproof bicycle you must

get correct tightening torque specications

from the bicycle or component manufacturer

or from your Authorised Nukeproof Dealer. If

SECTION 1 - before you ride

about the safe use of the

bicycle under all conditions.

There are risks associated

with the use of any bicycle

which cannot be predicted or

avoided, and which are the

sole responsibility of the rider.

E-BIKE WARNING

Any manipulation, modication or tuning of

E-Bike motors will void warranty and carries a

severe risk of injury and damage. If the motor

is modied, your E-Bike may no longer be

approved for use on public roads and forest

trails. Please check your local legislation to

ensure you are riding legally.

A SPECIAL NOTE FOR PARENTS

As a parent or guardian, you are responsible

for the activities and safety of your child, and

that includes making sure that the bicycle is

properly tted to the child; that it is in good

repair and safe operating condition; that you

and your child have learned and understand

the safe operation of the bicycle; and that

you and your child have learned, understand

and obey not only the applicable local motor

vehicle, bicycle and trafc laws, but also the

common sense rules of safe and responsible

cycling. As a parent, you should read this

manual, as well as review its warnings and the

bicycle’s functions and operating procedures

with your child, before letting your child ride

the bicycle.

Warning - Make sure that your child

always wears an approved bicycle

helmet when riding; but also make

sure that your child understands

that a bicycle helmet is for cycling

only and must be removed when

not riding. A helmet must not be

worn while playing, in play areas,

on playground equipment, while

climbing trees, or at any time while

not riding a bicycle. Failure to follow

this warning could result in serious

injury or death.

NOTE

We strongly urge you to read this manual

in its entirety before your rst ride on your

Nukeproof bicycle. At the very least, read and

make sure that you understand each point in

this section, and refer to the cited sections

on any issue which you don’t completely

understand.

Please note that not all Nukeproof bicycles

have all the features described in this manual.

If you are unsure on any features of your new

Nukeproof bicycle, please consult with your

detailer for further assistance.

you need to make an adjustment at home or in

the eld, we urge you to exercise care, and to

have the fasteners you worked on checked by

your Authorised Nukeproof Dealer as soon as

possible.

WARNING: Correct tightening force

on fasteners – nuts, bolts, screws

- on your bicycle is important. Too

little force, and the fastener may

not hold securely. Too much force,

and the fastener can strip threads,

stretch, deform, or break. Either way,

incorrect tightening force can result

in component failure, which can

cause you to lose control and fall.

Make sure nothing is loose. Lift the

front wheel off the ground by two or

three inches, then let it bounce on

the ground.

1.C.1. Tyres and Wheels

Make sure tyres are correctly inated (see

Section 4.G.1.). Check by putting one hand

on the saddle, one on the intersection of

the handlebars and stem, then bouncing

your weight on the bike while looking at tyre

deection. Compare what you see with how it

looks when you know the tyres are correctly

inated; and adjust if necessary. Are both tyres

in good condition? Spin each wheel slowly and

look for cuts in the tread and sidewall. Replace

damaged tyres before riding the bike. Are both

wheels true? Spin each wheel and check for

brake clearance and side-to-side wobble. If

a wheel wobbles side to side even slightly, or

tyres rub against or hits the frame or fork, take

the bike to a qualied bike shop to have the

wheel trued.

CAUTION: Wheels must be true to

ensure stability of the bike. Wheel

truing is a skill which requires special

tools and experience. Do not attempt

to true a wheel unless you have the

knowledge, experience and tools

needed to do the job correctly.

1.C.2. Brakes

Nukeproof bikes are equipped with powerful

modern disc brake systems. Disc brake

systems offer exceptional control and power.

Please note power will improve with some use

once the pads and discs have bedded in.

Check the brakes for proper operation (see

Section 4.C.). Squeeze the brake levers

and ensure there is a rm feel. Are all control

cables/hose lines seated and securely

engaged with no leaks? Do the brake pads

contact the disc squarely and make full contact

with the disc? Can you apply full braking

force at the levers without having them touch

the handlebar? If not, your brakes need

adjustment and/or bled. Do not ride the bike

until the brakes are properly adjusted/bled by a

professional bicycle mechanic.

1.C.3. Quick Release

Make sure the front wheel, rear wheel and seat

post quick releases are properly adjusted and

in the locked position. (See Section 4.B.)

1.C.4. Handlebar and saddle alignment

Make sure the saddle and handlebar stem are

parallel to the bike’s centreline and clamped

tight enough so that you can’t twist them out

of alignment. (See Section 3.B. and Section

3.C.)

1.C.5. Handlebar Ends

Make sure the handlebar grips are secure and

in good condition. If not, have your Authorised

Nukeproof Dealer replace them.

Make sure the handlebar ends are plugged. If

not, have your Authorised Nukeproof Dealer

plug them before you ride.

WARNING: Loose or damaged

handlebar grips can cause you to

lose control and fall. Unplugged

handlebars can cut you and cause

serious injury in an otherwise minor

accident.

1.C.6. REAR DERAILLEUR HANGER

Make sure the rear derailleur hanger is tight,

straight, and undamaged. If bent or broken,

have your Authorised Nukeproof Dealer

replace it before you ride. (See Section 5.B.)

1.D. FIRST RIDE

1.D.1. When you buckle on your helmet and

go for your rst familiarization ride on your

new bicycle, be sure to pick a controlled

environment, away from cars, other cyclists,

obstacles, or other hazards. Ride to become

familiar with the controls, features, and

performance of your new bike.

1.D.2. Familiarize yourself with the braking

action of the bike (see Section 4.C.). Test

the brakes at slow speed, putting your weight

toward the rear and gently applying the

brakes, rear brake rst. Sudden or excessive

application of the front brake could pitch you

over the handlebars.

Applying brakes too hard can lock up a wheel,

which could cause you to lose control and fall.

Skidding is an example of what can happen

when a wheel locks up. If your bicycle has

toe clips or clipless pedals, practice getting in

and out of the pedals. (See Section B.4. and

Section 4.E.4.)

1.D.3. Practice shifting the gears (see

Section 4.D.). Remember to never move the

shifter while pedalling backward, nor pedal

backwards immediately after having moved

the shifter. This could jam the chain and cause

serious damage to the bicycle. Check out the

handling and response of the bike for t and

comfort. If you have any questions, or if you

feel anything about the bike is not as it should

be, consult your Authorised Nukeproof Dealer

before your next ride.

2.A. THE BASICS

WARNING: Many countries require

specic safety devices. It is your

responsibility to familiarize yourself

with the laws of the region where you

ride and to comply with all applicable

laws, including properly equipping

yourself and your bike as the law

requires. Observe all local bicycle

laws and regulations. Observe

regulations about bicycle lighting,

reectors, licensing of bicycles, riding

on footpaths, laws regulating bike

path and trail use, helmet laws, child

carrier laws, and special bicycle

trafc laws. It’s your responsibility to

know and obey the laws.

2.A.1. Always wear a cycling helmet which

meets the latest certication standards and is

appropriate for the type of riding you do.

Always follow the helmet manufacturer’s

instructions for t, use and care of your

helmet. Most serious bicycle injuries involve

head injuries which might have been avoided

if the rider had worn an appropriate helmet.

If your helmet is damaged, do not use and

immediately replace.

WARNING: Failure to wear a helmet

when riding may result in serious

injury or death.

2.A.2. Always do the mechanical safety check

(Section 1.C.) before you get on a bike.

2.A.3. Be thoroughly familiar with the controls

of your bicycle:

• Brakes (Section 4.C.)

• Pedals (Section 4.E.)

• Shifting (Section 4.D.)

2.B.3. Look ahead, and be ready to avoid:

• Vehicles slowing or turning,

entering the road or your lane

ahead of you, or coming up

behind you.

• Parked car doors opening.

• Pedestrians stepping out.

• Children or pets playing near

the road.

• Potholes, sewer grating,

railroad tracks, expansion

joints, road or sidewalk

construction, debris and other

obstructions that could cause

you to swerve into trafc, catch

your wheel or cause you to

have an accident.

• The many other hazards and

distractions which can occur

on a bicycle ride.

2.B.4. Ride in designated bike lanes, on

designated bike paths or as close to the edge

of the road as possible, in the direction of

trafc ow or as directed by local governing

laws.

2.B.5. Stop at stop signs and trafc lights;

slow down and look both ways at street

intersections. Remember that a bicycle always

loses in a collision with a motor vehicle, so be

prepared to yield even if you have the right of

way.

2.B.6. Use approved hand signals for turning

and stopping.

2.B.7. Never ride with headphones. They

mask trafc sounds and emergency vehicle

sirens, distract you from concentrating on

what is going on around you, and their wires

can tangle in the moving parts of the bicycle,

causing you to lose control.

2.B.8. Never carry a passenger, unless it is a

small child wearing an approved helmet and

secured in a correctly mounted child carrier or

a child carrying trailer.

2.B.9. Never carry anything which obstructs

your vision or your complete control of the

bicycle, or which could become dangerous.

2.B.10. Never hitch a ride by holding on to

another vehicle.

2.B.11. Don’t do stunts, wheelies or jumps. If

you intend to do stunts, wheelies, jumps or go

racing with your bike despite our advice not to

then read Section 2.E. - Competition. Think

carefully about your skills before deciding to

take the large risks that go with this kind of

riding.

2.B.12. Don’t weave through trafc or make

any moves that may surprise people with

whom you are sharing the road.

2.B.13. Observe and yield the right of way.

2.B.14. Never ride your bicycle while under the

inuence of alcohol or drugs.

2.B.15. If possible, avoid riding in bad weather,

when visibility is obscured, at dawn, dusk or

in the dark, or when extremely tired. Each of

these conditions increases the risk of accident.

2.B.16. Always carry some form of

identication, so that people know who you

are in case of an accident; and take along

some cash for a candy bar, a cool drink, or an

emergency phone call.

2.C. WET WEATHER RIDING

WARNING:

Wet weather impairs traction,

braking and visibility, both for the

cyclist and for other vehicles sharing

the road. The risk of an accident

is dramatically increased in wet

conditions.

2.C.1. Under wet conditions, the stopping

power of your brakes (as well as the brakes of

other vehicles sharing the road) is dramatically

reduced and your tires don’t grip nearly as

well. This makes it harder to control speed

and easier to lose control. To make sure that

you can slow down and stop safely in wet

SECTION 2 - safety

2.A.4. Be careful to keep body parts and

other objects away from the sharp teeth of

chainrings, the moving chain, the turning

pedals and cranks, and the spinning wheels of

your bicycle.

2.A.5. Always wear:

• Shoes that will stay on your

feet and will grip the pedals.

Make sure that shoelaces

cannot get into moving parts

and never ride barefoot or in

sandals.

• Bright, visible clothing that

is not so loose that it can

be tangled in the bicycle or

snagged by objects at the side

of the road or trail.

• Protective eyewear, to protect

against airborne dirt, dust, and

bugs - tinted when the sun is

bright, clear when it’s not.

2.A.6. Don’t jump with your bike. Jumping

a bike can be fun; but it can put huge and

unpredictable stress on the bicycle and its

components. Riders who insist on jumping

their bikes risk serious damage, to their

bicycles as well as to themselves.

2.A.7. Before you attempt to jump or race with

your bike, read, and understand Section 2.E.

2.A.8. Ride at a speed appropriate for current

conditions and surroundings. Increased speed

means higher risk.

2.B. RIDING SAFETY

2.B.1. You are sharing the road or the path

with others - motorists, pedestrians, and other

cyclists. Respect their rights.

2.B.2. Ride defensively. Always assume that

others do not see you.

conditions, ride more slowly and apply your

brakes earlier and more gradually than you

would under normal, dry conditions. (See also

Section 4.C.)

WARNING:

Loose or damaged handlebar grips

can cause you to lose control and

fall. Unplugged handlebars can cut

you and cause serious injury in an

otherwise minor accident.

2.D. RIDING AT NIGHT

2.D.1. Riding a bicycle at night is many times

more dangerous than riding during the day.

A cyclist is very difcult for motorists and

pedestrians to see. Therefore, children should

never ride at dawn, at dusk or at night. Adults

who choose to accept the greatly increased

risk of riding at dawn, at dusk or at night need

to take extra care both riding and choosing

specialist equipment which helps reduce that

risk. Consult your Authorised Nukeproof Dealer

about night riding safety equipment.

WARNING:

Reectors are not a substitute for

required lights. Riding at dawn, at

dusk, at night or at other times of

poor visibility without an adequate

bicycle lighting system is dangerous

and may result in serious injury or

death.

2.D.2. Bicycle reectors are designed to

pick up and reect car lights and streetlights

in a way that may help you to be seen and

recognized as a moving cyclist.

CAUTION:

Check reectors and their mounting

brackets regularly to make sure that

they are clean, straight, unbroken,

and securely mounted. Have your

Authorised Nukeproof Dealer replace

damaged reectors and straighten or

tighten any that are bent or loose.

heavy or fast-moving trafc.

• Avoid road hazards.

• If possible, ride on familiar

routes.

2.D.5. If riding in trafc:

• Be predictable. Ride so that

drivers can see you and

predict your movements.

• Be alert. Ride defensively and

expect the unexpected.

• If you plan to ride in trafc

often, ask your Authorised

Nukeproof Dealer about trafc

safety classes or a good book

on bicycle trafc safety.

2.E. COMPETITION

2.E.1. By engaging in racing or aggressive

riding you voluntarily assume an increased risk

of injury or death. Not all bicycles are designed

for these types of riding, and those that may

not be suitable for all types of aggressive

riding. Check with your Authorised Nukeproof

Dealer or the bicycle’s manufacturer about the

suitability of your bicycle before engaging in

competition. When riding fast downhill, you can

reach excessive speeds and therefore face

higher risks due to reduced reaction time.

• Have your bicycle and

equipment carefully inspected

by a qualied mechanic

and be sure it is in perfect

condition.

• Take your bicycle to your

Authorised Nukeproof Dealer if

anything breaks or bends. Do

not ride your bicycle when any

part is damaged.

• Consult with expert riders and

race ofcials on conditions and

equipment advisable at the

site where you plan to ride.

• Wear appropriate safety

gear. Ultimately, it is your

responsibility to have proper

equipment and to be familiar

with course conditions.

WARNING: Although many

catalogues, advertisements, and

articles about cycling depict riders

engaged in various forms of racing,

this activity can be extremely

dangerous, increases your risk of

injury or death and increases the

severity of any injury. Remember

that the action depicted is being

performed by professionals with

many years of training and

experience. Know your limits and

always wear a helmet and other

appropriate safety gear. Even with

state-of-the-art protective safety

gear, you could be seriously injured

or killed when riding downhill at

speed or in competition.

CAUTION: Bicycles and bicycle

parts have limitations regarding

strength and integrity, and this type

of riding can increase the likelihood

of exceeding those limitations.

2.F. CHANGING COMPONENTS

2.F.1. There are many components and

accessories available to enhance the comfort,

performance, and appearance of your bicycle.

However, if you change components or add

accessories, you do so at your own risk. The

bicycle’s manufacturer may not have tested

that component or accessory for compatibility,

reliability, or safety on your bicycle. Before

installing any component or accessory,

including a different size tyre, make sure that

it is compatible with your bicycle by checking

with your Authorised Nukeproof Dealer. Be

sure to read, understand and follow the

instructions that accompany the products you

purchase for your Nukeproof bicycle.

WARNING: Failure to conrm

compatibility, properly install,

operate, and maintain any

WARNING:

Do not remove any installed front or

rear reectors or reector brackets

from your bicycle. They are an

integral part of the bicycle’s safety

system. Removing the reectors may

reduce your visibility to others using

the roadway. Being struck by other

vehicles may result in serious injury

or death. If your bike is supplied with

reectors and not installed, install

them to manufacturer’s instructions

and seek advice from your

Authorised Nukeproof Dealer.

2.D.3. If you choose to ride under conditions of

poor visibility, check and be sure you comply

with all local laws about night riding, and take

the following strongly recommended additional

precautions:

• Purchase and install battery

or generator powered head

and taillights which meet all

regulatory requirements and

provide adequate visibility.

• Wear light coloured, reective

clothing and accessories, such

as a reective vest, reective

arm and leg bands, reective

stripes on your helmet,

ashing lights attached to your

body and/or your bicycle. Any

reective device or light source

that moves will help you get

the attention of approaching

motorists, pedestrians, and

other trafc.

• Make sure clothing or anything

you may be carrying on the

bicycle does not obstruct a

reector or light.

• Make sure that your bicycle

is equipped with correctly

positioned and securely

mounted reectors.

2.D.4. While riding at dawn, at dusk or at night:

• Ride slowly.

• Avoid dark areas and areas of

component or accessory can result in

serious injury or death.

CAUTION: Changing the

components on your bike may void

the warranty. Refer to your warranty,

and check with your Authorised

Nukeproof Dealer before changing

the components on your bike.

2.G. MAXIMUM WEIGHT

2.G.1 Nukeproof bikes are designed and

tested to ISO 4210 / EN 15194 standards; our

bikes conform to the load tolerance of 120kg

which the standards require. If the user is over

this weight when kitted, we would recommend

regular inspection and maintenance to avoid

issues and expect wear and tear parts to be

replaced more often. Third party components

may have different load and weight standards,

any concerns with components weight limits

please consult with your Authorised Nukeproof

Dealer. We cannot guarantee the integrity of

the bike and its components if the user is over

120kg.

2.H. ELECTRIC BIKE

This section contains information about the

basic properties and components for E-Bike

customers. Please read any accompanying

manufacturer’s instructions for the components

and operation of your E-Bike. Please note your

E-Bike may have different components and

operation depending on model, any doubts or

concerns contact your Authorised Nukeproof

Dealer.

2.H.1. Differences between an E-Bike and

Bicycle

Compared to a pedal-operated bicycle, an

E-Bike will feature the following additional

components:

• Electric Assist Motor

• Battery

• Operating Control Unit

• Display

• Charger

The additional components of an E-Bike

translate into signicant differences between

an E-Bike and pedal-operated bicycle. Please

read Section 2 – Safety in full, and consider

the following when riding your E-Bike.

• An E-Bike is much heavier, and weight

is distributed differently, which will

change the E-Bikes handling. You

should familiarise yourself with the

bikes handling in a safe and trafc free

environment.

• The electric assist of an E-Bike will

inuence the braking behaviour,

please familiarise yourself with the

braking characteristics compared to a

regular bike. An E-Bike being heavier

can increase braking distances,

please ensure you are familiar with

the braking distances of your E-Bike in

different conditions and speeds.

• Increased breaking forces of a heavier

E-Bike may increase wear on brake

components, please ensure you

regularly have your brakes inspected

by a qualied mechanic or your

Authorised Authorised Nukeproof

Dealer.

• The electric motor assist will increase

the rider’s average speed. Adopt an

appropriate prudent riding style that

will ensure your safety and other trail

and road users safety considering the

higher average speed of an E-Bike.

• Only qualied mechanics with

accredited training can maintain and

repair an E-Bike electrical system.

Please take note of Section 5 -

Service, as your E-Bike will need to

be strictly maintained to ensure safety

and longevity.

• Modifying your E-Bike electrical motor/

system will void warranty and may

break local legislative laws.

2.H.3 Support While Riding

The electric motor only provides assistance

when you turn the pedals, the degree of

assistance is selected automatically in line

with:

• Your selected assistance

setting

• Your pedal force

• Load

• Speed

The electric motor only provides assistance

when you pedal up to the legislative speed

restriction in your country. If you reach a speed

higher than the limit the electric motor will

switch off automatically. If your speed drops

below the limit, the electric motor will switch on

again automatically.

2.H.4. Pushing/Walking Aid

Depending on the model of your E-Bike, it may

be installed with a pushing/walking aid. The

pushing/walking aid provides an assistance

when pushing your E-Bike. This function has

a speed limit which is dependent on local

legislation. The speed will also be affected by

the gear you have selected.

CAUTION: The cranks and pedals

will turn automatically when using the

pushing/walking aid, maintain a safe

distance from the pedals to ensure

you are not struck and to avoid injury.

Note

Correct t is an essential element of cycling

safety, performance, and comfort. To make the

adjustments to your bicycle, which result in

correct t for your body and riding conditions,

requires experience, skill, and special tools.

Always have your Authorised Nukeproof

Dealer make the adjustments on your bicycle;

or, if you have the experience, skill, and tools,

have your Authorised Nukeproof Dealer check

your work before riding. The t suggestions

below are based solely on safety concerns.

They specify the absolute minimum standards

to ride the bike, but by no means do they

guarantee optimal performance. Much more

elaborate t requirements are necessary to

ensure optimal performance. For the additional

performance tting requirements, please

consult with your Authorised Nukeproof Dealer.

WARNING: If your bicycle does not

t properly, you may lose control and

fall. If your new bike doesn’t t, ask

your Authorised Nukeproof Dealer to

exchange it before you ride it.

3.A. STANDOVER HEIGHT

Standover height is the basic element of bike

t. It is the distance from the ground to the top

of the bicycle’s frame at that point where your

crotch is when straddling the bike. To check

for correct standover height, straddle the

bike while wearing the kind of shoes in which

you’ll be riding, and bounce vigorously on

your heels. If your crotch touches the frame,

the bike is too big for you. Don’t even ride

the bike around the block. A bike which you

ride only on paved surfaces and never take

offroad should give you a minimum standover

height clearance of two inches (5cm). A bike

that you’ll ride on unpaved surfaces should

give you a minimum of three inches (7.5cm)

of standover height clearance. And a bike that

you’ll use off road should give you four inches

(10cm) or more of clearance.

WARNING: If you plan to use your

bike for jumping or competition, read

Section 2.E. again.

3.B. SADDLE POSITION

Correct saddle adjustment is an important

factor in getting the most performance and

comfort from your bicycle. If the saddle

position is not comfortable for you, see your

Authorised Nukeproof Dealer.

The saddle can be adjusted in three directions:

3.B.1. Up and down adjustment

To check for correct saddle height:

• Sit on the saddle.

• Place one heel on a pedal.

• Rotate the crank until the pedal with

your heel on it is in the down position

and the crank arm is parallel to the

seattube.

If your leg is not completely straight, your

saddle height needs to be adjusted. If your

hips must rock for the heel to reach the pedal,

the saddle is too high. If your leg is bent at

the knee with your heel on the pedal, the

saddle is too low. Once the saddle is at the

correct height, make sure that the seatpost

does not project from the frame beyond its

“Minimum Insertion” mark, which means that

the minimum insertion mark should never be

visible above the frame once adjusted to your

correct position. If the “Minimum Insertion”

mark is visible once your saddle is properly

adjusted, contact your Authorised Nukeproof

Dealer to have the seatpost replaced with a

SECTION 3 - fit

longer one or check the bike is the correct size

for the user. The seat clamp will need a 4mm

or 5mm Allen Key to loosen and tighten.

WARNING: If your seatpost is

inserted into the frame beyond

the Maximum Insertion mark, the

seatpost may break and/or the frame

will get damaged, which could cause

you to lose control and fall.

Note that some seatposts also have a second

insertion mark entitled “Maximum Insertion”. If

present on your bicycle, your seatpost should

never be lowered into the frame beyond the

“Maximum Insertion” point, meaning that this

line must always be visible above the frame

once the saddle is properly adjusted. If the

“Maximum Insertion” mark is no longer visible

once your saddle is properly adjusted, contact

your Authorised Nukeproof Dealer to have the

seatpost replaced with a shorter one.

Minimum saddle height is dened as the

smallest possible distance between the centre

of the bottom bracket and the top of the saddle

on a given bicycle. It can be measured along

the plane of the seat tube from the top of the

saddle to the centre of the crank axle. Several

factors can inuence the minimum saddle

height including thickness of the saddle,

design of the seatpost clamp, seatpost length,

frame size, and frame design. Nukeproof

does not specify the minimum saddle height

on our standard geometry tables due to the

variability of this dimension with component

changes; instead, we recommend consulting

your Authorised Nukeproof Dealer to assist in

determining appropriate sizing and in tting

your bicycle to you.

3.B.2. Front and back adjustment

The saddle can be adjusted forward or back to

help you get the optimal position on the bike.

Ask your Authorised Nukeproof Dealer to set

the saddle for your optimal riding position and

to show you how to make this adjustment.

A 5mm Allen Key is needed to make this

adjustment.

3.B.3. Saddle angle adjustment

Most people prefer a horizontal saddle; but

some riders like the saddle nose angled up or

down just a little. Your Authorised Nukeproof

Dealer can adjust saddle angle or teach you

how to do it. Small changes in saddle position

can have a substantial effect on performance

and comfort. To nd your best saddle position,

make only one adjustment at a time.

WARNING: After any saddle

adjustment, be sure that the saddle

adjusting mechanism is properly

tightened before riding. A loose

saddle clamp or seat post binder

can cause damage to the seat post

or can cause you to lose control

and fall. A correctly tightened saddle

adjusting mechanism will allow no

saddle movement in any direction.

Periodically check to make sure that

the saddle adjusting mechanism is

properly tightened.

If, despite carefully adjusting the saddle height,

tilt and fore and-aft position, your saddle is

still uncomfortable, you may need a different

saddle design. Saddles, like people, come in

many different shapes, sizes and resilience.

Your Authorised Nukeproof Dealer can help

you select a saddle which, when correctly

adjusted for your body and riding style, will be

comfortable.

WARNING: Some people have

claimed that extended riding with a

saddle, which is incorrectly adjusted,

or which does not support your pelvic

area correctly can cause short-term

or long-term injury to nerves and

blood vessels, or even impotence.

If your saddle causes you pain,

numbness, or other discomfort, listen

to your body and stop riding until

you see your Authorised Nukeproof

Dealer about saddle adjustment or a

different saddle.

3.C. HANDLEBAR HEIGHT AND ANGLE

Your bike is equipped with a “threadless”

stem, which clamps on to the outside of the

steerer tube. Your Authorised Nukeproof

Dealer may be able to change handlebar

height by moving height adjustment spacers

from below the stem to above the stem, or vice

versa. Otherwise, you’ll have to get a stem of

different length or rise. Consult your Authorised

Nukeproof Dealer.

Do not attempt to do this yourself, as it

requires special knowledge.

WARNING: Exceeding the maximum

spacer height can result in damage

to the fork’s steerer tube, which could

cause you to lose control and fall.

WARNING: On some bicycles,

changing the stem or stem height

can affect the tension of the front

brake cable, locking the front brake

or creating excess cable slack which

can make the front brake inoperable.

This should be noted with cable

operated disc brakes.

WARNING: The top of the stem,

where tted over the fork steerer

tube, must not extend more than

5mm above the top of the steerer.

If the stem is extended beyond

this height the stem may break or

damage the fork’s steerer tube,

which could cause you to lose control

and fall. Your Authorised Nukeproof

Dealer can also change the angle of

the handlebar.

WARNING: An insufciently

tightened stem binder bolt or

handlebar binder bolt may

compromise steering action, which

could cause you to lose control

and fall. Place the front wheel of

the bicycle between your legs and

attempt to twist the handlebar/ stem

assembly. If you can twist the stem

in relation to the front wheel, turn the

handlebars in relation to the stem,

or turn the aerobar extensions in

relation to the handlebar, the bolts

are insufciently tightened.

3.D. CONTROL POSITION ADJUSTMENTS

The angle of the brake and shift control levers

and their position on the handlebars can be

changed. Ask your Authorised Nukeproof

Dealer to make the adjustments for you.

3.E. BRAKE REACH

Many bikes have brake levers which can be

adjusted for reach. If you have small hands or

nd it difcult to squeeze the brake levers, your

Authorised Nukeproof Dealer can either adjust

the reach or t shorter reach brake levers.

WARNING: The shorter the brake

lever reach, the more critical it is

to have correctly adjusted brakes,

so that full braking power can be

applied within available brake lever

travel. Brake lever travel insufcient

to apply full braking power can result

in loss of control, which may result in

serious injury or death.

It’s important to your safety, performance, and

enjoyment to understand how things work

on your bicycle. We urge you to ask your

Authorised Nukeproof Dealer how to do the

things described in this section before you

attempt them yourself, and that you have your

Authorised Nukeproof Dealer check your work

before you ride the bike. If you have even the

slightest doubt as to whether you understand

something in this section of the manual, talk to

your Authorised Nukeproof Dealer.

4.A. INITIAL ASSEMBLY

Nukeproof bicycles are shipped from the

factory to the Authorised Nukeproof Dealer

only partially assembled. Your Authorised

Nukeproof Dealer will complete the assembly

of the bicycle, and perform any adjustments

required to make it t you. It is strongly

recommended that you allow your Authorised

Nukeproof Dealer to perform the assembly

and tting operations, as it requires specic

knowledge of each part, appropriate tools, and

understanding of the interactions of various

materials. Your bicycle is a high-performance

machine, much like a racing car, and as such

requires skilled maintenance to ensure your

bike functions safely and effectively.

Your Authorised Nukeproof Dealer will perform

the following assembly operations before your

bicycle is delivered to you:

• Fork cut to appropriate length.

• Headset and stem installed and

adjusted.

• Handlebars clamped into stem. (May

not be installed with mail order)

• Brake/shift levers installed onto

handlebars.

• Front brake installed on fork.

• Brake and shifter cables threaded and

attached.

• Brakes and derailleur adjusted.

• Handlebars wrapped with bar tape and

plugged.

• Seat and seatpost installed.

• Wheels installed. (May not be installed

with mail order)

• Pedals (of your choice) installed. (May

not be supplied and/or installed with

mail order)

If you choose to perform any assembly

operations yourself, ensure that all operations

are done in accordance with the specic

assembly instructions published by the

component manufacturer.

These assembly instructions are included

in the bike box provided to your Authorised

Nukeproof Dealer. Alternatively, assembly

instructions are usually posted on the

component manufacturer’s websites or are

available from their service departments.

4.A.1. Tools needed to assemble your bike

• Allan Keys – 4mm/5mm/6mm/8mm

• Pedal Spanner – 15mm

4.B. WHEELS

4.B.1. Wheel Quick Release

Warning: Riding with an improperly

adjusted wheel quick release can

allow the wheel to wobble or fall off

the bicycle, which can cause serious

injury or death. Therefore, it is

essential that you:

• Ask your Authorised Nukeproof

Dealer to help you make sure you

know how to install and remove your

wheels safely.

• Understand and apply the correct

technique for clamping your wheel in

place with a quick release.

• Each time, before you ride the bike,

check that the wheel is securely

clamped.

The wheel quick release uses a cam action

to clamp the bike’s wheel in place. Because

of its adjustable nature, it is critical that

you understand how it works, how to use it

properly, and how much force you need to

apply to secure the wheel.

Warning: The full force of the cam

action is needed to clamp the wheel

securely. Holding the nut with one

hand and turning the lever like a

wing nut with the other hand until

everything is as tight as you can get

it will not clamp the wheel safely in

the dropouts.

4.B.1.A. Adjusting the quick release

mechanism

The wheel hub is clamped in place by the

force of the quick release cam pushing against

one dropout and pulling the tension adjusting

nut, by way of the skewer, against the other

dropout. The amount of clamping force is

controlled by the tension adjusting nut. Turning

the tension adjusting nut clockwise while

keeping the cam lever from rotating increases

clamping force; turning it anti-clockwise while

keeping the cam lever from rotating reduces

clamping force. Less than half a turn of the

tension adjusting nut can make the difference

between safe clamping force and unsafe

clamping force.

4.B.1.B. Front wheel secondary retention

devices

Most bicycles have front forks which utilize a

secondary wheel retention device to reduce

the risk of the wheel disengaging from the

fork if the quick release is incorrectly adjusted.

Secondary retention devices are not a

substitute for correct quick release adjustment.

Secondary retention devices fall into two basic

categories:

4.B.1.B.1. The clip-on type is

a part which the manufacturer

adds to the front wheel hub or

front fork.

4.B.1.B.2. The integral type is

moulded, cast, or machined

into the outer faces of the

front fork dropouts. Ask your

Authorised Nukeproof Dealer

to explain the secondary

retention device on your bike.

Warning: Do not remove or disable

the secondary retention device. As its

name implies, it serves as a back-up

for a critical adjustment. If the quick

release is not adjusted correctly,

the secondary retention device

can reduce the risk of the wheel

disengaging from the fork. Removing

or disabling the secondary retention

device may also void the warranty.

Secondary retention devices are not

a substitute for correct quick release

adjustment. Failure to properly

adjust the quick release mechanism

can cause the wheel to wobble or

disengage which could cause you

to lose control and fall, resulting in

serious injury or death.

4.B.2. Removing and installing quick

release wheels

4.B.2.A. Removing a quick release front

wheel

4.B.2.A.1. If your bike has rim brakes,

disengage the brake’s quick release

mechanism to increase the clearance between

the tyre and the brake pads.

4.B.2.A.2. Move the wheel’s quick-release

lever from the locked or CLOSED position to

the OPEN position.

4.B.2.A.3. Quick release levers should

be embossed with the words “OPEN” and

“CLOSED” to indicate the current position of

the lever.

4.B.2.A.4. If your front fork does not have a

secondary retention device go to Section

4.B.2.B.

4.B.2.A.5. If your front fork has a clip-on type

of secondary retention device, disengage it,

and go to Section 4.B.2.B.

SECTION 4 - technical

If your front fork has an integral secondary

retention device, loosen the tension adjusting

nut enough to allow removing the wheel; then

go to the next step. Raise the front wheel a few

inches off the ground and tap the top of the

wheel with the palm of your hand to release

the wheel from the front fork.

4.B.2.B. Installing A quick release front

wheel

4.B.2.B.1. Move the quick-release lever so

that it curves away from the wheel. This is the

OPEN position.

4.B.2.B.2. With the steering fork facing

forward, insert the wheel between the fork

blades so that the axle seats rmly at the top

of the slots which are at the tips of the fork

blades – the fork dropouts. The quick-release

lever should be on the left side of the bicycle. If

your bike has a clip-on type secondary

retention device, engage it.

4.B.2.B.3. Holding the quick release lever in

the OPEN position with your right hand, tighten

the tension adjusting nut with your left hand

until it is nger tight against the fork dropout.

4.B.2.B.4. While pushing the wheel rmly to

the top of the slots in the fork dropouts, and

at the same time centring the wheel rim in the

fork, move the quick release lever upwards

and swing it into the CLOSED position. The

lever should now be parallel to the fork blade

and curved toward the wheel. To apply enough

clamping force, you should have to wrap your

ngers around the fork blade for leverage, and

the lever should leave a clear imprint in the

palm of your hand.

Warning: Securely clamping the

wheel takes considerable force. If

you can fully close the quick release

without wrapping your ngers around

the fork blade for leverage, and the

lever does not leave a clear imprint

in the palm of your hand, the tension

is insufcient. Open the lever; turn

the tension adjusting nut clockwise a

quarter turn; then try again.

4.B.2.B.5. If the lever cannot be pushed all

the way to a position parallel to the fork blade,

return the lever to the OPEN position. Then

turn the tension adjusting nut anti-clockwise

one-quarter turn and try tightening the lever

again.

4.B.2.B.6. Re-engage the brake quick release

mechanism to restore correct brake pad-to-rim

clearance; spin the wheel to make sure that

it is centred in the frame and clears the brake

pads; then squeeze the brake lever and make

sure that the brakes are operating correctly.

4.B.2.C. Removing a quick release rear

wheel

4.B.2.C.1. Shift the rear derailleur to high gear

(the smallest, outermost rear sprocket).

4.B.2.C.2. If your bike has rim brakes,

disengage the brake’s quick release

mechanism to increase the clearance between

the wheel rim and the brake pads.

4.B.2.C.3. Pull the derailleur body back with

your right hand.

4.B.2.C.4. Move the quick release lever to the

OPEN position.

4.B.2.C.5. Lift the rear wheel off the ground a

few inches and, with the derailleur still pulled

back, push the wheel forward and down until it

comes out of the rear dropouts.

4.B.2.D. Installing a quick release rear

wheel

4.B.2.D.1. Make sure that the rear derailleur is

still in its outermost, high gear, position.

4.B.2.D.2. Pull the derailleur body back

with your right hand, turn off the clutch if the

derailleur has this feature, engage the clutch

again once wheel is installed.

4.B.2.D.3. Move the quick release lever to the

OPEN position. The lever should be on the

side of the wheel opposite the derailleur and

freewheel sprockets.

4.B.2.D.4. Put the chain on top of the smallest

freewheel sprocket. Then, insert the wheel up

and back into the frame dropouts and pull it all

the way into the dropouts.

4.B.2.D.5. Tighten the quick release adjusting

nut until it is nger tight against the frame

dropout; then swing the lever toward the front

of the bike until it is parallel to the frame’s

chainstay or seatstay and is curved toward

the wheel. To apply enough clamping force,

you should have to wrap your ngers around a

frame tube for leverage, and the lever should

leave a clear imprint in the palm of your hand.

Warning: Securely clamping

thewheel takes considerable force.

If you can fully close the quick

release without wrapping your ngers

around the seatstay or chainstay

for leverage, and the lever does not

leave a clear imprint in the palm of

your hand, the tension is insufcient.

Open the lever; turn the tension

adjusting nut clockwise a quarter

turn; then try again. The rear wheel

must be secured to the bicycle frame

with sufcient force so that it cannot

be pulled forward by the chain, even

under the greatest pedalling force.

If the wheel moves under pedalling

force, the tyre can touch the frame,

which can cause you to lose control

and fall.

4.B.2.D.6. If the lever cannot be pushed all

the way to a position parallel to the chainstay

or seatstay tube, return the lever to the OPEN

position. Then turn the adjusting nut anti-

clockwise one-quarter turn and try tightening

again.

4.B.2.D.7. Push the rear derailleur back into

position.

4.B.2.D.8. Re-engage the brake quick release

mechanism to restore correct brake pad-to-rim

clearance; spin the wheel to make sure that

it is centred in the frame and clears the brake

pads, then squeeze the brake lever and make

sure that the brakes are operating correctly.

4.B.2.E. Installing wheels with through

axles

Nukeproof bikes typically will use through

axles, typically a 6mm Allen Key for the front

and 5mm Allen Key for the rear axles.

1. Insert the wheels to the fork and

frame dropouts, ensure the rotor

is aligned with the caliper to avoid

damage when installing. For the rear

wheel please ensure the gears are

in the smallest sprocket and pull the

derailleur rearwards to give more room

for install. Ensure the hub endcaps are

seated correctly in the dropouts for a

secure t.

2. Apply a little grease to the axle and

threads and push through the dropouts

and hubs until axle cannot be pushed

further.

3. Tighten the through axle clockwise to

the Nm found on the axle, if no Nm is

displayed, please consult with your

Authorised Nukeproof Dealer.

4. If the through axle is stiff when

installing, it may be cross-threading,

stop immediately and check seating

of hubs and dropouts. Any further

concerns please consult with your

Authorised Nukeproof Dealer.

5. If the forks have pinch bolt dropouts,

reference the forks manufacturer

guides for correct installation.

6. If the through axles have quick release

levers, please reference the axles

manufacturer’s instructions for correct

install.

7. Ensure the correct tools are used

when tting and removing through

axles, if you are unsure, please consult

with your Authorised Nukeproof

Dealer.

8. Ensure the through axles are checked

before and after each ride to ensure

they are tight.

9. Riding with loose through axles can

result in loss of control, injury, and

death.

If you are unsure on tting wheels with through

axles, please consult with your Authorised

Nukeproof Dealer.

4.B.2.F. Installing wheels with female axles

and male bolts

Some Nukeproof bikes will be supplied with a

Female axle with Male bolt, a 5mm Allen Key

is needed for the install of the Male Bolt.

Female axles are threaded and Male bolts

screw into this thread.

1. Insert the wheels to the fork and frame

dropouts, ensure the rotor is aligned

with the caliper to avoid damage when

installing. For the rear wheel please

ensure the gears if applicable are in

the smallest sprocket and pull the

derailleur rearwards to give more room

for install. Ensure the hub endcaps are

seated correctly in the dropouts for a

secure t.

2. Screw the Male bolts clockwise to the

hub axle, consult with your Authorised

Nukeproof Dealer for the correct Nm

torque.

Ensure the correct tools are used when tting

and removing Male bolts, if you are unsure,

please consult with your Authorised Nukeproof

Dealer.

If the Male bolt is stiff when installing, it may be

cross-threading, stop immediately and check

seating of hubs and dropouts. Any further

concerns please consult with your Authorised

Nukeproof Dealer.

Ensure the Male Bolts are checked before and

after each ride to ensure they are tight.

Riding with loose Male bolts can result in loss

of control, injury, and death.

If you are unsure on tting wheels with Male

bolts, please consult with your Authorised

Nukeproof Dealer.

4. C. BRAKES

Warning: Riding with improperly

adjusted brakes or worn brake

pads is dangerous and can result in

serious injury or death.

Applying brakes too hard or too

suddenly can lock up a wheel, which

could cause you to lose control and

fall. Sudden or excessive application

of the front brake may pitch the rider

over the handlebars, which may

result in serious injury or death.

See the brake manufacturer’s

instructions for operation and care

of your brakes. If you do not have

the manufacturer’s instructions, see

your Authorised Nukeproof Dealer or

contact the brake manufacturer.

4.C.1. Brake controls and featues

Nukeproof bikes are all equipped with powerful

modern disc brake systems. Disc brake

systems offer exceptional control and power.

Please note power will improve with some

use once the pads and discs have bedded

in. Ensure you familiarise yourself with which

lever operates the front or rear brakes. Your

Authorised Nukeproof Dealer will set the

brakes to the way they are typically used in

your country, but please check lever orientation

or get the brakes set to your preference by

your Authorised Nukeproof Dealer. Adjust

the position of the brake levers so the lever

is in a comfortable position and easy to pull.

Brake performance will vary with riding terrain

and weather conditions, familiarise yourself

with your brake’s performance in different

conditions.

4.C.2. How brakes work

The braking action of a bicycle is a function

of the friction between the brake surfaces –

Nukeproof bikes use disc brake. These work

with friction between brake pads and disc

surface.

To make sure that you have maximum friction

available, keep your brakes clean and free of

dirt, lubricants, waxes, or polishes. Brakes are

designed to control your speed, not just to stop

the bike.

Maximum braking force for each wheel occurs

at the point just before the wheel “locks up”

(stops rotating) and starts to skid. Once the tire

skids, you lose most of your stopping force and

all directional control.

You need to practice slowing and stopping

smoothly without locking up a wheel.

The technique is called progressive brake

modulation. Instead of jerking the brake lever

to the position where you think you’ll generate

appropriate braking force, squeeze the lever,

progressively increasing the braking force.

If you feel the wheel begin to lock up, release

pressure just a little to keep the wheel rotating

just short of lockup.

It’s important to develop a feel for the amount

of brake lever pressure required for each

wheel at different speeds and on different

surfaces.

To better understand this, experiment a little

by walking your bike and applying different

amounts of pressure to each brake lever, until

the wheel locks.

When you apply one or both brakes, the

bike begins to slow, but your body wants to

continue at the speed at which it was going.

This causes a transfer of weight to the front

wheel (or, under heavy braking, around the

front wheel hub, which could send you ying

over the handlebars).

A wheel with more weight on it will accept

greater brake pressure before lockup; a wheel

with less weight will lock up with less brake

pressure.

So, as you apply brakes and your weight is

transferred forward, you need to shift your

body toward the rear of the bike, to transfer

weight back on to the rear wheel; and at the

same time, you need to both decrease rear

braking and increase front braking force.

This is even more important on descents

because descents shift weight forward. Two

keys to effective speed control and safe

stopping are controlling wheel lockup and

weight transfer.

Practice braking and weight transfer

techniques where there is no trafc or other

hazards and distractions.

Everything changes when you ride on loose

surfaces or in wet weather.

Tyre adhesion is reduced, so the wheels have

less cornering and braking traction and can

lock up with less brake force.

Moisture or dirt on the brake pads reduces

their ability to create friction.

The way to maintain control on loose or wet

surfaces is to go more slowly to begin with.

4.D. GEARS

Your multi-speed bicycle will have a derailleur

drivetrain.

4.D.1. How a derailleur drivetrain works

The parts of the gear-changing mechanism

include:

• A rear cassette or freewheel sprocket

cluster

• A rear derailleur (Nukeproof bikes do

not use front derailleurs)

• Single right shifter

• One front sprocket called a chainring

• A drive chain

4.D.1.A. Shifting Gears

There are several different types and styles of

shifting controls: levers, twist grips, triggers,

combination shift/brake controls and push-

buttons. Ask your Authorised Nukeproof Dealer

to explain the type of shifting controls that are

on your bike, and to show you how they work.

The vocabulary of shifting can be confusing:

• A downshift is a shift to a “lower” or

“slower” gear, one which is easier to

pedal.

• An upshift is a shift to a “higher” or

“faster”, harder to pedal gear.

What’s confusing is that what’s happening at

the front derailleur is the opposite of what’s

happening at the rear derailleur (for details,

read the instructions on Shifting the Rear

Derailleur and Shifting the Front Derailleur

below). For example, you can select a gear

which will make pedalling easier on a hill

(make a downshift) in one of two ways: shift

the chain down the gear “steps” to a smaller

gear at the front, or up the gear “steps” to a

larger gear at the rear. So, at the rear gear

cluster, what is called a downshift looks like

an upshift. The way to keep things straight is

to remember that shifting the chain in towards

the centreline of the bike is for accelerating

and climbing and is called a downshift. Moving

the chain out or away from the centreline of

the bike is for speed and is called an upshift.

Whether upshifting or downshifting, the bicycle

derailleur system design requires that the drive

chain be moving forward and be under at least

some tension. A derailleur will shift only if you

are pedalling forward.

Warning: Never move the shifter

while pedalling backward, nor pedal

backwards immediately after having

moved the shifter. This could jam the

chain and cause serious damage to

the bicycle.

4.D.1.B. Shifting the rear derailleur

The rear derailleur is controlled by the right

shifter. The function of the rear derailleur is to

move the drive chain from one gear sprocket

to another. The smaller sprockets on the gear

cluster produce higher gear ratios. Pedalling

in the higher gears requires greater pedalling

effort but takes you a greater distance with

each revolution of the pedal cranks. The

larger sprockets produce lower gear ratios.

Using them requires less pedalling effort

but takes you a shorter distance with each

pedal crank revolution. Moving the chain

from a smaller sprocket of the gear cluster

to a larger sprocket, results in a downshift.

Moving the chain from a larger sprocket to a

smaller sprocket, results in an upshift. For the

derailleur to move the chain from one sprocket

to another, the rider must be pedalling forward.

4.D.1.C. Shifting the front derailleur

Typically, Nukeproof bikes do not come with a

front derailleur, but do take note this may not

be the case going forward. The front derailleur,

which is controlled by the left shifter, shifts

the chain between the larger and smaller

chainrings. Shifting the chain onto a smaller

chainring makes pedalling easier (a downshift).

Shifting to a larger chainring makes pedalling

harder (an upshift).

4.D.1.D. Which gear should I be in?

Find the “starting gear” which is right for your

level of ability - a gear which is hard enough

for quick acceleration but easy enough to let

you start from a stop without wobbling and

experiment with upshifting and downshifting

to get a feel for the different gears. At rst,

practice shifting where there are no obstacles,

hazards, or other trafc, until you’ve built up

your condence. Learn to anticipate the need

to shift, and shift to a lower gear before the

hill gets too steep. If you have difculties with

shifting, the problem could be mechanical

adjustment. See your Authorised Nukeproof

Dealer for help.

Warning: Never shift a derailleur

onto the largest or the smallest

sprocket if the derailleur is not

shifting smoothly. The derailleur

may be out of adjustment and the

chain could jam, causing you to lose

control and fall.

4.E. Fit Bars

If your bike is supplied with handlebars

removed for shipping and you wish to install

yourself without the assistance of a qualied

mechanic or Authorised Nukeproof Dealer,

please use the following steps:

• Unscrew face plate bolts from stem

with a 4mm Allen Key, remove stem

face plate and bolts, set aside safely

for installing later.

• Place bars to stem, using the set-up

lines if present on your bars to position

the bars centrally. Ensure cables and

brake lines are not tangled at this

point.

• Tighten the face plate bolts to the

stem with a 4mm Allen Key, start with

the top bolts and move to the bottom

bolts. Ensure bolt torque is evenly

spread around all four bolts before

fully tightening. Reference the torque

details on the stem, if no details are

present, please consult with your

authorised Authorised Nukeproof

Dealer.

• You can adjust the roll of the bars

back or forward at this point to your

personal preference. Ensure the bars

are still centred when adjusting and

use the markings on the bars to help.

4.E. PEDALS

Nukeproof bicycles are not shipped with

pedals, which permits the Authorised

Nukeproof Dealer and customer to select and

install pedals appropriate for the intended

use of the bicycle. Please consult with your

Authorised Nukeproof Dealer to ensure

you have been provided all manufacturer’s

documentation for the installed pedals and

take responsibility to ensure that you have

read and fully understand all documentation

before riding any bicycle equipped with

unfamiliar pedals. In some cases, a mail

order bike may be supplied with pedals at the

Authorised Nukeproof Dealer’s discretion,

please use a local accredited mechanic to

install these pedals, if you install the pedals

yourself, please follow pedal manufactures

install instructions.

4.F.1. Pedal Install

If your bike is supplied with pedals and you

wish to install yourself without the assistance

of a qualied mechanic or Authorised

Nukeproof Dealer please use the following

steps:

• Please check with your Authorised

Nukeproof Dealer for the correct tools

to install your pedals. Typically, pedals

will need a 15mm Spanner or 6/8mm

Allen Key to install.

• Identify left and right pedals, this is

very important to ensure safe tting.

Right pedal is for drive-side, left pedal

is for non-drive side. Pedals will have a

L (Left) and R (Right) marking. Cross-

threading pedals to cranks can lead to

failure, injury, and death. Any doubts,

please contact a qualied mechanic or

your authorised Authorised Nukeproof

Dealer.

• Before installing pedals, please

check crank threads are clean and no

damage is present.

• Grease both left and right pedal

threads.

• Align pedal threads to cranks, either

use the 15mm spanner or 6/8mm

Allen Key to turn the pedal spindle.

Turn the R (Right) pedal clockwise,

and the L (Left) pedal anti-clockwise

to tighten. If there is any resistance or

pedal is not screwing in straight, STOP

IMMEDIATELY. Ensure threads are

seated correctly before fully installing.

4.E.2. Toe Overlap is when your toe can touch

the front wheel when you turn the handlebars

to steer while a pedal is in the forward most

position. This is common on small-framed

bicycles and is avoided by keeping the inside

pedal up and the outside pedal down when

making sharp turns. On any bicycle, this

technique will also prevent the inside pedal

from striking the ground in a turn.

Warning: Toe Overlap could

cause you to lose control and fall.

Ask your Authorised Nukeproof

Dealer to help you determine if the

combination of frame size, crank

arm length, tyre size, pedal design,

and shoes you choose to use

results in pedal overlap. Note that

component changes to your bicycle

(cranks, tyres, pedals) can result in

a reduction of toe-clearance; consult

your Authorised Nukeproof Dealer

about any component changes

and use caution when rst riding

the bicycle following a component

change. Whether you have overlap

or not, you must keep the inside

pedal up and the outside pedal down

when making sharp turns.

4.E.3. Some bicycles come equipped with

pedals that have sharp and potentially

dangerous surfaces. These surfaces are

designed to add safety by increasing grip

between the rider’s shoe and the pedal. If

your bicycle has this type of high-performance

pedal, you must take extra care to avoid

serious injury from the pedal’s sharp surfaces.

Based on your riding style or skill level, you

may prefer a less aggressive pedal design or

chose to ride with shin pads. Your Authorised

Nukeproof Dealer can show you several

options and make suitable recommendations.

4.E.4. Toe clips and straps are a means to

keep feet correctly positioned and engaged

with the pedals. The toe clip positions the

ball of the foot over the pedal spindle,

which gives maximum pedalling power. The

toe strap, when tightened, keeps the foot

engaged throughout the rotation cycle of the

pedal. While toe clips and straps give some

benet with any kind of shoe, they work most

effectively with cycling shoes designed for

use with toe clips. Your Authorised Nukeproof

Dealer can explain how toe clips and straps

work. Shoes with deep treaded soles or welts

which might make it more difcult for you to

remove your foot should not be used with toe

clips and straps.

Warning: Getting into and

out of pedals with toe clips

and straps requires skill which

can only be acquired with

practice. Until it becomes a

reex action, the technique

requires concentration which

can distract your attention and

cause you to lose control and

fall. Practice the use of toe

clips and straps where there

are no obstacles, hazards, or

trafc. Keep the straps loose,

and don’t tighten them until

your technique and condence

in getting in and out of the

pedals warrants it. Never ride

in trafc with your toe straps

tight.

4.E.5. Clipless pedals (sometimes called “step-

in” pedals are another means to keep feet

securely in the correct position for maximum

pedalling efciency. They have a plate, called

a “cleat,” on the sole of the shoe, which clicks

into a mating spring-loaded xture on the

pedal. They only engage or disengage with a

very specic motion which must be practiced

until it becomes instinctive. Clipless pedals

require shoes and cleats which are compatible

with the make and model pedal being used.

Many clipless pedals are designed to allow

the rider to adjust the amount of force needed

to engage or disengage the foot. Follow the

pedal manufacturer’s instructions or ask

your Authorised Nukeproof Dealer to show

you how to make this adjustment. Use the

easiest setting until engaging and disengaging

becomes a reex action, but always make

sure that there is sufcient tension to prevent

unintended release of your foot from the pedal.

Warning: Clipless pedals are

intended for use with shoes

specically made to t them

and are designed to rmly

keep the foot engaged with

the pedal. Using shoes which

do not engage the pedals

correctly is dangerous.

4.E.5. Practice is required to learn to engage

and disengage the foot safely. Until engaging

and disengaging the foot becomes a reex

action, the technique requires concentration

which can distract your attention and cause

you to lose control and fall. Practice engaging

and disengaging clipless pedals in a place

where there are no obstacles, hazards,

or trafc; and be sure to follow the pedal

manufacturer’s setup and service instructions.

Always try to disengage at least one foot

before stopping so you are prepared to set

a foot down for balance. If you do not have

the manufacturer’s instructions, see your

Authorised Nukeproof Dealer, or contact the

manufacturer for advice.

4.F. TYRES AND TUBES

4.F.1. Tyres

Bicycle tyres are available in many designs

and specications, ranging from general-

purpose designs to tyres designed to perform

best under very specic weather or terrain

conditions. If, once you’ve gained experience

with your new bike, you feel that a different

tyre might better suit your riding needs, your

Authorised Nukeproof Dealer can help you

select the most appropriate design.

The size, pressure rating, and on some high-

performance tyres the specic recommended

use, are marked on the sidewall of the tyre.

The part of this information which is most

important to you is tyre

pressure.

Warning: Never inate a tyre

beyond the maximum pressure

marked on the tyre’s sidewall.

Exceeding the recommended maximum

pressure may blow the tyre off the rim, which

could cause damage to the bike and injury to

the rider and bystanders. The best and safest

way to inate a bicycle tyre to the correct

pressure is with a bicycle pump which has a

built-in pressure gauge.

Warning: There is a safety

risk in using service station

air hoses or other air

compressors. They are not

made for bicycle tyres. They

move a large volume of air

very rapidly and will raise the

pressure in your tyre very

rapidly, which could cause the

tube to explode.

Tyre pressure is given either as maximum

pressure or as a pressure range. How a tyre

performs under different terrain or weather

conditions depends largely on tyre pressure.

Inating the tyre to near its maximum

recommended pressure gives the lowest

rolling resistance; but also produces the

harshest ride. High pressures work best on

smooth, dry pavement.

Very low pressures, at the bottom of the

recommended pressure range, give the best

performance on smooth, slick terrain such as

hard-packed clay, and on deep, loose surfaces

such as deep, dry sand. Tyre pressure that

is too low for your weight and the riding

conditions can cause a puncture of the tube by

allowing the tyre to deform sufciently to pinch

the inner tube between the rim and the riding

surface.

Caution: Pencil type

automotive tyre gauges can

be inaccurate and should not

be relied upon for consistent,

accurate pressure readings.

Instead, use a high-quality dial

gauge.

Ask your Authorised Nukeproof Dealer to

recommend the best tyre pressure for the

kind of riding you will most often do and have

the Authorised Nukeproof Dealer inate your

tyres to that pressure. Then, check ination

as described in Section 1.C. so you’ll know

how correctly inated tyres should look and

feel when you don’t have access to a gauge.

Some tyres may need to be brought up to

pressure every week or two. Some special

high-performance tyres have unidirectional

treads. Their tread pattern is designed to work

better in one direction than in the other. The

sidewall marking of a unidirectional tyre will

have an arrow showing the correct rotation

direction. If your bike has unidirectional tyres,

be sure that they are mounted to rotate in the

correct direction.

4.F.2. Tyre valves

There are primarily two kinds of bicycle tube

valves: The Schrader valve and the Presta

valve. The bicycle pump you use must have

the tting appropriate to the valve stems on

your bicycle.

The Schrader valve is like the valve on a car

tyre. To inate a Schrader valve tube, remove

the valve cap and clamp the pump tting onto

the end of the valve stem. To let air out of a

Schrader valve, depress the pin in the end of

the valve stem with the end of a key or other

appropriate object.

The Presta valve has a narrower diameter

and is only found on bicycle tyres. To inate

a Presta valve tube using a Presta headed

bicycle pump, remove the valve cap; unscrew

(anti-clockwise) the valve stem lock nut; and

push down on the valve stem to free it up.

Then push the pump head on to the valve

head and inate. To inate a Presta valve with

a Schraeder pump tting, you’ll need a Presta

adapter (available at your local bike shop)

which screws on to the valve stem once you’ve

freed up the valve. The adapter ts into the

Schrader pump tting. Close the valve after

ination. To let air out of a Presta valve, open

the valve stem lock nut and depress the valve

stem.

Warning: Patching a tube is

an emergency repair. If you do

not apply the patch correctly

or apply several patches,

the tube can fail, resulting in

possible tube failure, which

could cause you to lose control

and fall. Replace a patched

tube as soon as possible.

4.F.3. Clincher and tubular tyres

There are primarily two kinds of bicycle tyres:

The clincher tyre and the tubular tyre.

Clincher tyres are shaped like a “U” in cross

section, with wire or Kevlar beads on the outer

edge of both sides that hook onto the rim and

hold the tire in place on the wheel over the

inner tube. Tubular tyres do not have beads –

the outer edges of the tyre are sewn together

around the inner tube, which is then glued to

the rim to hold it in place.

Your Nukeproof bicycle will be equipped with

clincher tyres from the factory, however riders

may wish to purchase a second set of wheels

utilising tubular tyres for our gravel models. If

you install wheels with tubular tyres on your

bicycle, it is very important that you obtain and

read all safety information about tubulars from

the wheel and tyre manufacturers, in particular

the information on the proper technique for

gluing the tyres to the rim. Improperly glued

tubular tyres can separate from the rim

causing a serious crash. It is up to the rider to

take responsibility for ensuring their tubular

wheels and tyres are safe to use.

Warning: Improperly installed

tubular tyres can separate

from the rims during a ride,

possibly causing a serious

crash that may result in injury

or death.

4.G. TIGHTENING OF FASTENERS

Your Nukeproof bicycle is equipped with

precision components which require precise

adjustment and care to function properly.

Whenever components are changed or

adjusted on the bicycle, it is critical for safety

and performance reasons that all fasteners be

tightened in accordance with the listed values

below. It is recommended that you permit

your Authorised Nukeproof Dealer to perform

the following adjustments, as they have the

proper tools and experience to ensure it is

done correctly. Improper adjustments can

result in safety hazards – ensure you read all

applicable documentation and have the correct

tools prior to attempting any adjustments

yourself.

Note that prior to assembling and tightening

any bolts, all threads must be generously

greased with a quality, non-lithium type grease.

Torque wrenches with scale appropriate for the

torque setting are strongly recommended for

tightening all threaded fasteners.

Nukeproof strongly recommends the use of

carbon assembly compound/friction paste for

all areas of clamping to carbon bre, such as

the seatpost to frame, the stem to fork, and the

handlebar to stem joints. Benets to using this

paste include reduced corrosion potential, and

a decrease in required clamping force needed

to support a given load. The paste should be

evenly spread on the carbon surface under the

clamped area.

Warning: Under-tightening or over-

tightening fasteners can result in

damage to the bicycle that can lead

to possible failure, which could cause

you to lose control and fall, resulting

in injury or death.

4.H. FORK LIMITS

The fork length also detailed as axle to crown

(A-C) cannot be exceeded. If you wish to

change your fork, please consult with your

Authorised Nukeproof Dealer that the bikes

maximum A-C is not exceeded. Using a fork

that exceeds the A-C may lead to frame failure,

injury, or death.

4.I. SHOCK SIZE / TUNE / UPGRADING

If you wish to change your shock for

an upgrade or a different model to your

preference, please consult with your

suspension supplier and Authorised Nukeproof

Dealer to ensure the shock is the correct size,

tting and the tune suits the kinematics of your

Nukeproof bicycle.

4.J. FRAME NUMBER

The majority of Nukeproof Bike’s unique

frame numbers are found on the underside of

the bottom bracket shell. The unique frame

number for a Megawatt is found inside the

frame and behind the motor housing. To

view the frame number at the back of the

motor housing the air from the rear shock

needs released allowing the rear triangle

to rise and give visibility. Your Authorised

Nukeproof Dealer and Nukeproof Bikes do

not have an obligation to keep a record of this

number. Please take a note of the number

for insurances and theft prevention/recovery

purposes.

4.K. MAXIMUM TYRE WIDTH

Do not exceed the fork and frame maximum

tyre widths. Check with your Authorised

Nukeproof Dealer the maximum tyre width

that can be installed to your specic bike.

Please note some manufacturer tyre and

rim combinations can be wider when tted

together, always check for clearance when

tyres are changed to a different model. Tyre

rub can damage frame and will not be covered

by warranty if incorrect tyre size has been

used. Tyres rubbing on frame and forks can

cause instability when riding, leading to loss of

control, injury, and death.

Warning: Technological advances

have made bicycles and bicycle

components more complex, and the

pace of innovation is increasing.

It is impossible for this manual to

provide all the information required

to properly repair and/or maintain

your bicycle. To help minimize the

chances of an accident and possible

injury, it is critical that you have any

repair or maintenance which is not

specically described in this manual

performed by your dealer. Equally

important is that your individual

maintenance requirements will be

determined by everything from your

riding style to geographic location.

Consult your Authorised Nukeproof

Dealer for help in determining your

maintenance requirements.

Warning: Many bicycle service

and repair tasks require special

knowledge and tools. Do not begin

any adjustments or service on your

bicycle until you have learned from

your Authorised Nukeproof Dealer

how to properly complete them.

Improper adjustment or service may

result in damage to the bicycle or in

an accident which can cause serious

injury or death.

If you want to learn to do major service and

repair work on your bike:

• Ask your Authorised Nukeproof Dealer

for copies of the manufacturer’s

installation and service instructions

for the components on your bike or

contact the component manufacturer.

thoroughly and lightly oil the chain. Wipe

off excess oil. Lubrication is a function of

climate. Talk to your Authorised Nukeproof

Dealer about the best lubricants and the

recommended lubrication frequency for your

area.

5.A.4. After every long or hard ride or after

every 10 to 20 hours of riding

Squeeze the front brake and rock the bike

forward and back. Does everything feel

solid? If you feel a clunk with each forward or

backward movement of the bike, you probably

have a loose headset. Have your Authorised

Nukeproof Dealer check it.

Lift the front wheel off the ground and swing it

from side to side. Does it feel smooth? If you

feel any binding or roughness in the steering,

you may have a tight headset. Have your

Authorised Nukeproof Dealer check it.

Inspect both rims for damage. Check the

spoke-holes on the rim for any cracks that

may have formed due to fatigue If cracks

are found do not ride it – take the wheel

to your Authorised Nukeproof Dealer for

replacement. Also inspect the brake surface

for wear (relative to other surfaces). If a

noticeable amount of wear has occurred, do

not ride it – take the wheel to your Authorised

Nukeproof Dealer for inspection and possible

replacement. Ignoring these signs of wheel

wear or damage can lead to failures of the rim.

Grab one pedal and rock it toward and away

from the centre line of the bike; then do the

same with the other pedal. Anything feel

loose? If so, have your Authorised Nukeproof

Dealer check it.

Look at the brake pads. If they are starting to

look worn or not hitting the wheel rim squarely

then have your Authorised Nukeproof Dealer

adjust or replace them.

Carefully check the control cables and cable

housings for signs of rust, kinks, and fraying.

If you notice as of these signs, have your

Authorised Nukeproof Dealer replace them.

Squeeze each adjoining pair of spokes on

either side of each wheel between your thumb

and index nger. Do they all feel about the

same? If any feel loose, have your Authorised

Nukeproof Dealer checks the wheel for tension

and trueness.

Check to make sure that all parts and

accessories are still secure and tighten any

which are not.

• Check the frame, particularly in

the area around all tube joints; the

handlebars; the stem; and the seatpost

for any deep scratches, cracks, or

discolouration. These are signs of

stress-caused fatigue and indicate that

a part is at the end of its useful life and

needs to be replaced.

Warning: Like any mechanical

device, a bicycle and its components

are subject to wear and stress.

Different materials and mechanisms

wear or fatigue from stress at

different rates and have different life

cycles. If a component’s life cycle

is exceeded, the component can

suddenly and catastrophically fail,

causing serious injury or death to the

rider.

Scratches, cracks, fraying, and discolouration

are signs of stress caused fatigue and indicate

that a part is at the end of its useful life and

needs to be replaced. While the materials and

workmanship of your bicycle or of individual

components may be covered by a warranty for

a specied period of time by the manufacturer,

this is no guarantee that the product will last

the term of the warranty. Product life is often

related to the kind of riding you do and to the

treatment to which you submit the bicycle.

The bicycle’s warranty is not meant to suggest

that the bicycle cannot be broken or will

last forever. It only means that the bicycle is

covered subject to the terms of the warranty.

5.A.5. As required

If either brake lever fails the Mechanical Safety

Check (Section 1.C. - Mechanical Safety),

don’t ride the bike. Have your Authorised

Nukeproof Dealer check the brake. If the chain

won’t shift smoothly and quietly from gear to

gear, the derailleur is out of adjustment. See

your Authorised Nukeproof Dealer.

SECTION 5 - service

• Ask your Authorised Nukeproof Dealer

to recommend a book on bicycle

repair.

• Ask your Authorised Nukeproof Dealer

about the availability of bicycle repair

courses in your area.

We recommend that you ask your Authorised

Nukeproof Dealer to check the quality of your

work the rst time you work on something and

before you ride the bike, just to make sure that

you did everything correctly. Since that will

require the time of a mechanic, there may be a

modest charge for this service.

5. A. SERVICE INTERVALS

Some service and maintenance can and

should be performed by the owner and require

no special tools or knowledge beyond what is

presented in this manual.

The following are examples of the type of

service you should perform yourself. All other

service, maintenance and repair should be

performed in a properly equipped facility

by a qualied bicycle mechanic using the

correct tools and procedures specied by the

manufacturer.

5.A.1. Break-in Period

Your bike will last longer and work better if

you break it in before riding it hard. Control

cables and wheel spokes may stretch or “seat”

when a new bike is rst used and may require

readjustment by your Authorised Nukeproof

Dealer. Section 1.C. - Mechanical Safety

will help you identify some things that need

readjustment.

5.A.2. Before every ride

Check Section 1.C. - Mechanical Safety

5.A.3. After every long or hard ride

If the bike has been exposed to water or grit;

or at least every 100 miles: Clean the bike

5.A.6. Every 25 (hard off-road) to 50 (on-

road) hours of riding:

Take your bike to your Authorised Nukeproof

Dealer for a complete check-up.

5. B. bike SUSTAINing AN IMPACT

First, check yourself for injuries, and take care

of them as best you can. Seek medical help if

necessary.

Next, check your bike for damage on the spot.

Following any crash, take your bike to your

Authorised Nukeproof Dealer for a thorough

check.

Warning: A crash or other impact

can put extraordinary stress on

bicycle components, causing them

to fatigue prematurely. Components

suffering from stress fatigue can

fail suddenly and catastrophically,

causing loss of control, serious injury

or death.

5. C. REPLACEMENT PARTS

Over time due to wear out of components

or a desire to upgrade, it is likely that one

or more components of your bicycle will

need to be replaced. Please consult your

Authorised Nukeproof Dealer when choosing

replacement parts – it is very important that

suitable, genuine parts are selected and

properly installed to maintain the safety and

performance characteristics of your Nukeproof

bicycle.

Warning: Failure to select and

properly install suitable, genuine

replacement parts may lead to

unforeseen changes in the safety

and performance characteristics of

your bicycle.

It is recommended that you use Authorised

Nukeproof Dealer-recommended OEM

replacement parts for any components of

your bicycle that require replacement. Your

Nukeproof bicycle was carefully designed and

tested with the components provided, and

changes to these parts can result in different
