Assembly

Before riding, ensure that all required fasteners are tightened to the correct torque. • Ensure

that the tyres are inflated to within specification (printed on the tyre sidewall), and that the

brakes are operating correctly. • Assembly may require 2 people. • Do NOT allow children to perform the

assembly. • Additional tools to those supplied (if any) may be required for assembly, such as a torque

wrench, pliers etc.

The bicycle comes with some minor assembly required, and may include some necessary tools.

Handlebars

1. Carefully place the bicycle assembly on a flat surface so that it rests on the front fork and rear wheel.

2. Slide the handlebar stem (A) into the fork tube until fully inserted.

3. Rotate the handlebar assembly, if required, so it is aligned "square" to the front fork. That is, the

handlebar will be at 90° to the bicycle frame when the front wheel is straight.

4. Using a 6mm Allen key and torque wrench, tighten the handlebar stem bolt (B) to the specified torque.

The orientation of the front fork is correct when the

brake caliper is facing forward. The orientation of the

handlebar is correct when the control cables and

brake levers are facing forward. It is ESSENTIAL that the fork and

handlebar are assembled correctly. The adjacent image (bicycle

shown fully assembled) shows correct fork / handlebar assembly.

5. You can rotate the handlebar tube (C) and handlebar neck (C1)

for a more comfortable riding position. Using a 6mm Allen Key,

loosen the handlebar tube clamping bolt (D), then rotate the

handlebar tube forward or backwards as needed - ensure it

remains centred. Using a 6mm Allen Key and Torque Wrench,

tighten (rotate right) the handlebar tube clamping bolt to the

specified torque. Using a 6mm Allen Key, remove the handlebar

neck lock bolt (D1) and the grip lock piece (D2) from the front of the handlebar neck (C1). Rotate the

handlebar neck forward or backwards as needed. Insert the grip lock piece (D2) and handlebar neck lock

bolt (D1) back into the front of the handlebar neck and using a 6mm Allen Key and Torque Wrench,

tighten (rotate right) the handlebar neck lock bolt to the specified torque.

Seat

When setting seat height, it is important to ensure that the resulting ride position is not only

comfortable, but also safe. You should be able to remain stable and properly handle the bicycle

when at a standstill, touch the ground etc. You should also be able to comfortably reach the pedals

when riding and comfortably and safely operate the handlebars and all controls. A good reference height for

the seat is at hip height. Do NOT have the seat raised enough so you can see the maximum height marker

on the seat post. • Ensure that when the seat is clamped, you cannot rock it back and forth or rotate it.

1. Insert the seat post/seat assembly (E) into the bicycle frame and lower it to a comfortable position – do

NOT have the seat raised enough so you can see the maximum height marker (F) on the seat post.

2. Rotate the clamp lever (G) from the unlock position (AA) to the lock position (BB). If the seat post is not

clamped firmly, increase pressure by unlocking the clamp, then rotating the adjustment knob (H) right

(clockwise) a ¼ turn, then re-test and adjust as necessary.

The seat angle can also be adjusted, again for best comfort. To

adjust angle, using a 13mm spanner, loosen (rotate left) the seat

clamp nuts (CC) on either side of the seat until the front of the

seat can be moved up/down. Set the angle as required, then

tighten the nuts securely.

Note that small changes in seat position can have a substantial

effect on comfort. It is recommended to make seat adjustments in

small increments and test the position, then re-adjust as

necessary.

Front Wheel

1. Turn the bicycle over so it is resting on the handlebar and

seat. Remove the black plastic spacer from the wheel fork.

2. Install the front wheel by lowering it into the slots at the bottom of the fork legs, making sure that the

brake disc (M) sits into slot on the brake pad assembly (N).

3. Remove the plastic nut (P) and washer (Q) from the axle skewer (O) and then slide the skewer through

the centre of the wheel.

4. Fasten the nut and washer back onto the skewer. As you tighten, check the tension on the quick release

handle (R), it should require firm pressure to close, locking the wheel in place.

Pedals

It is critical that you follow the pedal to crank arm attachment procedure carefully to ensure

correct assembly. • During assembly, do NOT use excessive force to screw the pedals into the

crank arms – this may indicate misalignment of the pedals or mis-matched threads. If the pedal does not

"feel right" when being screwed in, STOP immediately and check that it is the correct pedal and that it is

aligned properly with the crank arm. Failure to follow the instructions here or take due care may

damage the equipment and void any product warranty.

1. Starting with the right-hand crank arm (O), identify the right-hand pedal assembly (P), which is identified

by having the pedal bolt stamped "R".

2. Very carefully begin screwing the pedal bolt into the crank arm (rotate right / clockwise). If the bolt does

not "feel right" when being screwed in, STOP immediately and check that it is the correct bolt and that it

is aligned properly with the crank arm. Screw the pedal bolt in fully, then tighten to the specified torque

(P) using a 15mm spanner and torque wrench.

3. Repeat the above procedure for the left-hand crank arm, noting that the pedal bolt and crank arm

thread is left-hand (rotate left / anti-clockwise to tighten) and that the pedal bolt is stamped "L".

Note: If there are no Left and Right markings on the pedals, sit the pedals side by side and inspect the

thread on each. As shown in the image below, the thread on the left pedal starts high on the left side,

and the thread on the right pedal starts high on the right side.

Pedal Assistance

Charge the battery prior to use. • Pedal assistance is not mandatory for riding – normal bicycle riding

("pedal power") alone can be used. It is recommended to use pedal assistance when necessary,

and not rely on it solely. When using pedal assistance, also pedal for best efficiency. • The bicycle

must be moving, or have sufficient pressure placed on the pedals (in a forward direction) to activate pedal

assistance. • If you apply the brakes when pedal assistance is active, the drive provided by the motor

reduces in proportion to how much braking pressure you apply. Once the bicycle reaches a sufficiently slow

speed or stops completely, pedal assistance automatically deactivates.

The bicycle pedal assistance system comprises an electric motor (A) built into the rear wheel hub, a battery

pack (B) with key security (C) and charging port (D) (under the handle), pedal assist throttle (E), and display

(F).

Using Pedal Assistance

1. Place the security key in the battery pack key slot and rotate to the "O" (ON) position. Once the key is in

the ON position, it cannot be removed from the key slot.

2. Begin moving using pedal power, press the pedal assist throttle downward to activate the motor.

3. After riding, rotate the key to the "X" (OFF) position and remove the key.

Understanding the Display

The display has two functions:

•The Mode section consists of three lights which indicate the level of

pedal assistance provided.

−One light: low level assistance / speed

−Two lights: medium level assistance / speed

−Three lights: high level assistance / speed

•The power section indicates the battery charge level, where one bar is

minimum, and five bars is full.

Guidelines for Using Pedal Assistance

To get the best performance and service life from the pedal assistance

system, understand and apply the following techniques:

•When pedal assistance is active, the drive motor engages to provide assistance only while the bicycle is

in motion and you are pedalling. The amount of assistance provided depends on your pedalling force

and the level of pedal ride assistance currently selected (where applicable) and / or being applied.

•Pedal assistance progressively reduces as bicycle speed increases, and stops completely when the

current speed exceeds 25kmh. Pedal assistance re-engages when speed drops below 25kmh (provided

you are pedalling).

•Start moving from stationary by pedalling as per a normal bicycle. Using pedal assistance only when

"pushing off" places undue loads on the system and uses a lot of energy.

•It is recommended to pedal as per a normal bicycle when riding up inclines. Using pedal assistance only

when climbing uses a lot of battery energy.

•Pedal assistance automatically reduces or disengages whenever the brakes are activated (and / or

when you stop pedalling).

Using Gears

Some model bicycles are equipped with gears. Gears are used to change the

ratio between rotations of the rear wheel and the crank set. This enables you

to pedal less and travel faster on flat or downhill sections, or pedal faster and

travel slower to climb hills. Gearing is independent to pedal assistance, so

pedal assistance operates the same regardless of selected gear. Remember,

however, that pedal assistance is "governed" by overall speed.

The selectable gears (A) are located on the rear wheel, known as a "gear

cluster" or "cassette". The larger the gear, the less number of rotations per

rotation of the crank. The largest gear is the "lowest" and is referred to as "1".

As each gear becomes smaller, it is a "higher" gear then the previous and is

numbered sequentially. The number of gears may vary between different

models. Beneath the gear cluster is the derailleur mechanism (B), which

moves the chain so it runs on different gears. The derailleur is operated by

the rider using controls mounted on the handlebars. The gear change is

"indexed" so each gear selection positively engages – this is factory set and

should require no adjustment. There may be slight variations between bicycle

models in method to change gear "up" (from a lower gear to a higher gear), or

to change gear "down" (from a higher gear to a lower gear). The image shows

a "6-speed" type that uses a button (C) for changing up gears (push button to

activate derailleur), and a lever (D) for changing down gears (rotate lever

forward to activate derailleur).

Guidelines for Using Gears

To get the best performance and service life from the gear change system, understand and apply the

following techniques:

•You MUST be pedalling during gear changes.

•Do not attempt to change multiple gears in a single action. Allow each gear change to complete fully

before the next change.

•Always use an appropriate gear for your speed, the terrain and incline. This helps you ride most

efficiently.

•Keep the chain and gears properly lubricated and clean.

•If you notice noise after changing gear or an ability to select a gear or the chain not running smoothly,

have the gear system inspected and adjusted by a bicycle mechanic or suitably qualified person.

Using Brakes

All bicycle models are equipped with a front and rear wheel braking system. Brakes are used to slow the

bicycle down. The braking systems may use different mechanics, however, the functionality is the same, and

that is to change the energy of the moving bicycle into heat energy ("friction"):

•For disc brakes, this means pads made from a special friction material pinching against a disc mounted

to the centre of the bicycle wheel.

•For rim type "caliper" or "noodle" brakes, this means rubber blocks pinching the outer rim of the bicycle

wheel (not the tyre).

•For drum brakes, this means pushing sections (known as "shoes") of special friction material against the

inside of cylinder fixed to the centre of the bicycle wheel.

Typical Disc Brake Typical Rim Brake Typical Drum Brake

The brakes are operated by the rider through levers mounted to the

handlebars. The left-hand lever operates the rear brake, the right-

hand lever operates the front brake. The ability of the rider to

adequately slow and/or stop the bicycle depends largely on the skill

of the rider, the surface being ridden on and other factors such as

rain, tyres, adjustment and condition of the brake parts etc.

Guidelines for Using Brakes

To get the best performance and service life from the brake system, understand and apply the following

techniques:

•In wet conditions, which reduces friction, always provide additional distance for braking and

adjust how quickly you apply the brakes.

•When applying the brakes, particularly the front brake, use a lower pressure to start with until you feel

the brakes starting to "bite", then increase pressure as required. Do NOT over-apply the brakes and

cause the wheel to stop rotating – this may result in loss of control.

•Maintain the brake friction components (pads, shoes, rubbers) in good condition and replace when they

reach the wear limit.

•Maintain brake adjustment so that the brakes perform effectively, the levers are comfortably positioned,

and there is not excessive play in adjustable components.

•If the brakes are not performing effectively, making abnormal noise or any part is not serviceable or

cannot be adjusted correctly, have the brakes inspected and adjusted by a bicycle mechanic or suitably

qualified person.

•If the brake cables become frayed or otherwise damaged, have them replaced by a bicycle mechanic or

suitable qualified person.

Batteries and Battery Charging

Never modify the electrical system. Alterations may cause a fire, resulting in serious injury

and could also damage the electrical system. • Charge with the supplied charger only. Use of

the wrong charger may cause a fire or explosion, resulting in serious injury. • Ensure the voltage and

frequency of the charger is compatible with mains electrical supply. • Use the battery charger in dry locations

only. • The battery must be charged before first use. • For maximum battery performance and service life,

charge the battery after each use, and charge at temperatures between 0 and 40°C (32 and 104°F). • Battery

charging generally takes 4 to 6 hours from discharged to fully charged. Do NOT charge the battery

continuously for more than 24 hours. • If the bicycle has not been used for over 4 weeks, charge the battery

before use. • Always switch the bicycle OFF after each use.

The battery pack can be recharged repeatedly. However, rechargeable batteries eventually need to be

replaced. A significantly reduced operating period after charging indicates that the battery is no longer

serviceable and should be replaced. Discard old batteries in an environmentally responsible manner.

The battery charger has a charge status LED indicator:

•Red - Battery charging.

•Green - Battery fully charged.

To charge the battery:

1. Lift the handle at the top of the battery pack to expose the

charging port (A), then plug the charger connector into the

charging port.

2. Connect the charger to a mains electrical supply and switch

ON. The indicator LED on the charger illuminates red to

show the battery is charging.

3. When the battery is charged (approximately 6 hours), the

charger indicator LED illuminates green. Disconnect the

charger from the electrical supply, then disconnect it from

the bicycle. Lower the battery pack handle to protect the

bicycle charging port.

Removing the Battery Pack

1. To remove the battery, insert the key into the keyhole in the ON position. Apply pressure to push the key

towards the battery pack so that the keyhole is depressed. While it’s depressed, turn the key anti-

clockwise towards the OFF position.

2. The battery pack is now unlocked and can be released from the bicycle. Raise the battery handle and

pull the battery upwards to remove it.

Maintenance

Some maintenance activities described may be beyond the scope of some users. Do NOT

attempt procedures that you are not comfortable with, or do not have the necessary tools,

experience or knowledge for – take the unit to an authorised service centre or qualified technician for

servicing. Items in the maintenance schedule below that are recommended to be performed by a qualified

technician are highlighted yellow. • Failure to follow the maintenance recommendations, using incorrect

or non-compatible accessories or replacement parts, or general negligence may result in making the

product warranty void. Improper adjustment or service may result in damage to the bicycle or make it

hazardous. • Maintenance requirements may be affected by any number of factors from your riding style to

geographic location. • When new, parts of the bicycle may "break-in" over the course of the first approximate

100km of riding, possibly including the stretching of cables, spoke tension changes etc. It is recommended to

have the bicycle inspected and serviced at an authorised service centre or by a qualified technician. • The

bicycle components are subject to wear and stress. If a component is weakened through stress, age etc, it

may fail without warning. It is important to regularly inspect the bicycle for any signs of component fatigue –

look for cracks, fraying, discoloration etc, as this may indicate that a part is near the end of its useful life and

should be replaced.

•Clean the bicycle with a soft, damp cloth – do NOT use high-pressure water cleaners or hoses,

pressurised air, solvents, abrasives etc. For the console, battery and motor, do NOT use any liquids.

•When transporting in a vehicle, it is recommended to have the battery out of the bicycle during transport.

•Store the bicycle where it will be protected from rain, sun etc to help prevent corrosion, fading etc.

•For safety, longest possible service life and reliability, maintain the bicycle properly. Use the maintenance

schedule below for guidance. It is very important that you check certain systems and components before

each and every ride. The proper condition and function of these systems is critical to your safety.

Battery Storage

When storing the batteries for a long period of time:

•Charge the batteries at least every 30 days to avoid capacity loss. Batteries slowly self-discharge when

unused over a long period. If the battery cells are left at a critically low charge state, the lifespan and

capacity will be permanently reduced.

•Always disconnect the charger from the mains electrical supply and battery before storing the battery.

•Avoid storing batteries in extreme temperatures, whether hot or cold. The recommended battery

storage temperature is between 0 and 25°C (32 to 77°F). Avoid exposing batteries to temperatures at

or above 40°C (104°F) for extended periods.

•Batteries are best kept in a cool, dry place. Do not allow batteries to accumulate condensation, as this

may cause shorting or corrosion.

Battery Fuse

Use fuses of the same type only – the rating (in Amperes) is printed on the end of the fuse. • If the

fuse "blows" regularly, have the bicycle inspected at an authorised service centre.

The bicycle battery / electrical system may feature fuse protection to prevent damage in the event of a short-

circuit, overload or over-current situation. For example, if the electrical system is exposed to excessive

moisture. On some model bicycles, the fuse is accessible and can be easily replaced. If the fuse is "blown",

the bicycle electronics will not be available until the fuse is replaced. To replace the fuse:

1. Using a suitable screwdriver, remove (rotate left) the fuse holder (A) on the battery pack until fully

unscrewed, then pull the fuse holder and fuse (B) from the bicycle.

2. Discard the blown fuse. Insert the replacement fuse into the fuse holder.

3. Insert the fuse and fuse holder to the bicycle, and re-install (rotate right) the fuse holder until fully

seated.
