GENERAL WARNING:
Like any sport, bicycling 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 avoided, 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 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.

A special note for parents:
As a parent or guardian, you are responsible for the activities and safety
of your minor child, and that includes making sure that the bicycle is properly
fitted 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 traffic laws, but also the common
sense rules of safe and responsible bicycling. 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 bicycling 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.
WARNING: This product may contain chemicals known to
the State of California to cause cancer and birth defects or
other reproductive harm, including paint, lubricants, and
various metals. Wash hands thoroughly after handling
this product.

1. First
NOTE: We strongly urge you to read this Manual in its entirety before your rst
ride. 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 bicycles have all of the features described in
this Manual. Ask your dealer to point out the features of your bicycle.
A.Biket
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 dealer to exchange it before you ride it.
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.
3. Are saddle and seat post securely clamped? A correctly tightened saddle will
allow no saddle movement in any direction. See Section 3.B.
4. Are the stem and handlebars at the right height for you? If not, see Section
3.C.
5. Can you comfortably operate the brakes? If not, you may be able to adjust
their angle and reach. See Section 3.D and 3.E.
6. Do you fully understand how to operate your new bicycle? If not, before your
rst ride, have your dealer explain any functions or features which you do not
understand.
B.Safetyrst
1. Always wear an approved helmet when riding your bike, and follow the
helmet manufacturer’s instructions for t, use and care.
2. Do you have all the other required and recommended safety equipment?
See Section 2. It’s your responsibility to familiarize yourself with the laws of the
areas where you ride, and to comply with all applicable laws.
3. Do you know how to correctly secure your front and rear wheels? Check
Section 4.A.1 to make sure. Riding with an improperly secured wheel can cause
the wheel to wobble or disengage from the bicycle, and cause serious injury or
death.
4. If your bike has toeclips 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.
5. Do you have “toe overlap”? On smaller framed bicycles your toe or toeclip
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 toeclip
overlap.
6. Does your bike have suspension? If so, check Section 4.F. Suspension
can change the way a bicycle performs. Follow the suspension manufacturer’s
instructions for use, adjustment and care.
C. Mechanical Safety Check
Routinely check the condition of your bicycle before every ride.
 Nuts,boltsscrews&otherfasteners: Because manufacturers use

4
a wide variety of fastener sizes and shapes made in a variety of materials,
often differing by model and component, the correct tightening force or torque
cannot be generalized. To make sure that the many fasteners on your bicycle
are correctly tightened, refer to the Fastener Torque Specications in Appendix
D of this manual or to the torque specications in the instructions provided by
the manufacturer of the component in question. Correctly tightening a fastener
requires a calibrated torque wrench. A professional bicycle mechanic with a
torque wrench should torque the fasteners on you bicycle. If you choose to work
on your own bicycle, you must use a torque wrench and the correct tightening
torque specications from the bicycle or component manufacturer or from your
dealer. If 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 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 loose 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. Anything sound, feel or look
loose? Do a visual and tactile inspection of the whole bike. Any loose parts or
accessories? If so, secure them. If you’re not sure, ask someone with experience
to check.
 Tires&Wheels: Make sure tires 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 tire
deection. Compare what you see with how it looks when you know the tires are
correctly inated; and adjust if necessary.
 Tires in good shape? Spin each wheel slowly and look for cuts in the tread
and sidewall. Replace damaged tires before riding the bike.
 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 rubs against or hits
the brake pads, take the bike to a qualied bike shop to have the wheel trued.
CAUTION: Wheels must be true for rim brakes to work effectively.
Wheel trueing 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.
 Wheel rims clean and undamaged? Make sure the rims are clean and
undamaged at the tire bead and, if you have rim brakes, along the braking
surface. Check to make sure that any rim wear indicator marking is not visible at
any point on the wheel rim.
WARNING: Bicycle wheel rims are subject to wear. Ask your dealer
about wheel rim wear. Some wheel rims have a rim wear indicator
which becomes visible as the rim’s braking surface wears. A visible

5
rim wear indicator on the side of the wheel rim is an indication that the
wheel rim has reached its maximum usable life. Riding a wheel that is at the
end of its usable life can result in wheel failure, which can cause you to
loose control and fall.
 Brakes: Check the brakes for proper operation (see Sections 4.C).
Squeeze the brake levers. Are the brake quick-releases closed? All control
cables seated and securely engaged? If you have rim brakes, do the brake
pads contact the wheel rim squarely and make full contact with the rim? Do the
brakes begin to engage within an inch of brake lever movement? Can you apply
full braking force at the levers without having them touch the handlebar? If not,
your brakes need adjustment. Do not ride the bike until the brakes are properly
adjusted by a professional bicycle mechanic.
 Wheelretentionsystem: Make sure the front and rear wheels are
correctly secured. See Section 4.A
 Seatpost: If your seat post has an over-center cam action fastener for
easy height adjustment, check that it is properly adjusted and in the locked
position.See Section 4.B.
 Handlebarandsaddlealignment: Make sure the saddle and handlebar
stem are parallel to the bike’s center line and clamped tight enough so that you
can’t twist them out of alignment. See Sections 3.B and 3.C.
 Handlebarends: Make sure the handlebar grips are secure and in good
condition. If not, have your dealer replace them. Make sure the handlebar ends
and extensions are plugged. If not, have your dealer plug them before you ride.
If the handlebars have bar end extensions, make sure they are clamped tight
enough so you can’t twist them.
WARNING: Loose or damaged handlebar grips or extensions can
cause you to lose control and fall. Unplugged handlebars or
extensions can cut you and cause serious injury in an otherwise
minor accident.
VERY IMPORTANT SAFETY NOTE:
Please also read and become thoroughly familiar with the important
information on the lifespan of your bicycle and its components in Appendix
B on Page 43.
D. First ride
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.
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 toeclips or clipless pedals, practice getting in and out of the

6
pedals. See paragraph B.4 above and Section 4.E.4.
If your bike has suspension, familiarize yourself with how the suspension
responds to brake application and rider weight shifts. See paragraph B.6 above
and Section 4.F.
Practice shifting the gears (see Section 4.D). Remember to never move the
shifter while pedaling 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; and check the comfort.
If you have any questions, or if you feel anything about the bike is not as it
should be, consult your dealer before you ride again.
2. Safety
A. The Basics
WARNING:Theareainwhichyouridemayrequirespecicsafety
devices. It is your responsibility to familiarize yourself with the laws of
the area 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, licensing of bicycles, riding on sidewalks, laws
regulating bike path and trail use, helmet laws, child carrier laws, special
bicycletrafclaws.It’syourresponsibilitytoknowandobeythelaws.
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.
WARNING: Failure to wear a helmet when riding may result in serious
injury or death.
2. Always do the Mechanical Safety Check (Section 1.C) before you get on a
bike.
3. Be thoroughly familiar with the controls of your bicycle: brakes (Section
4.C.); pedals (Section 4.E.); shifting (Section 4.D.)
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.
5. Always wear:
• Shoes that will stay on your feet and will grip the pedals. Make sure that
shoe laces 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.

7
• Protective eyewear, to protect against airborne dirt, dust and bugs — tinted
when the sun is bright, clear when it’s not.
6. Don’t jump with your bike. Jumping a bike, particularly a BMX or mountain
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. Before you attempt to jump, do stunt
riding or race with your bike, read and understand Section 2.F.
7. Ride at a speed appropriate for conditions. Higher speed means higher risk.
B. Riding Safety
1. Obey all Rules of the Road and all local trafc laws.
2. You are sharing the road or the path with others — motorists, pedestrians
and other cyclists. Respect their rights.
3. Ride defensively. Always assume that others do not see you.
4. 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.
• Pot holes, 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.
5. 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.
6. 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.
7. Use approved hand signals for turning and stopping.
8. Never ride with headphones. They mask trafc sounds and emergency
vehicle sirens, distract you from concentrating on what’s going on around you,
and their wires can tangle in the moving parts of the bicycle, causing you to lose
control.
9. 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.
10. Never carry anything which obstructs your vision or your complete control
of the bicycle, or which could become entangled in the moving parts of the
bicycle.
11. Never hitch a ride by holding on to another vehicle.
12. 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, read Section 2.F,
Downhill, Stunt or Competition Biking, now. Think carefully about your skills
before deciding to take the large risks that go with this kind of riding.
13. Don’t weave through trafc or make any moves that may surprise people
with whom you are sharing the road.
14. Observe and yield the right of way.

8
15. Never ride your bicycle while under the inuence of alcohol or drugs.
16. 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.
C. Off Road Safety
We recommend that children not ride on rough terrain unless they are
accompanied by an adult.
1. The variable conditions and hazards of off-road riding require close attention
and specic skills. Start slowly on easier terrain and build up your skills. If your
bike has suspension, the increased speed you may develop also increases your
risk of losing control and falling. Get to know how to handle your bike safely
before trying increased speed or more difcult terrain.
2. Wear safety gear appropriate to the kind of riding you plan to do.
3. Don’t ride alone in remote areas. Even when riding with others, make sure
that someone knows where you’re going and when you expect to be back.
4. Always take along some kind of identication, so that people know who you
are in case of an accident; and take along some cash for food, a cool drink or an
emergency phone call.
5. Yield right of way to pedestrians and animals. Ride in a way that does not
frighten or endanger them, and give them enough room so that their unexpected
moves don’t endanger you.
6. Be prepared. If something goes wrong while you’re riding off-road, help may
not be close.
7. Before you attempt to jump, do stunt riding or race with your bike, read and
understand Section 2.F.
Off Road respect
Obey the local laws regulating where and how you can ride off-road, and
respect private property. You may be sharing the trail with others — hikers,
equestrians, other cyclists. Respect their rights. Stay on the designated trail.
Don’t contribute to erosion by riding in mud or with unnecessary sliding. Don’t
disturb the ecosystem by cutting your own trail or shortcut through vegetation
or streams. It is your responsibility to minimize your impact on the environment.
Leave things as you found them; and always take out everything you brought in.
D. Wet Weather Riding
WARNING: Wet weather impairs traction, braking and visibility, both
for the bicyclist and for other vehicles sharing the road. The risk of an
accident is dramatically increased in wet conditions.
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 conditions,
ride more slowly and apply your brakes earlier and more gradually than you
would under normal, dry conditions. See also Section 4.C.
