BICYCLE SETUP
Correct Bicycle Size
Riding a bicycle that is not correctly sized to the rider may result
in the rider’s feet not being able to touch the ground and
balance the bicycle, properly reach the handlebar for steering or
braking, and loss of control when pedaling.
Use the wheel size in the following table as a guide to match the
rider and bicycle. For example, bicycles with a wheel size of 12
inches t a rider that is 28 to 38 inches tall. Note: Some bicycles
such as folding bicycles may have smaller wheels but sll t
adults.
If the bicycle has a top tube on the frame, check that there is
one to three inches of clearance between the rider and the top
tube. Figure 1.1
Wheel Size Riders Approximate Height
12 inch 28 - 38 inches tall
16 inch 38 - 48 inches tall
18 inch 42 - 52 inches tall
20 inch 48 - 60 inches tall
24 inch 56 - 66 inches tall
26 inch, 27.5 inch,
29 inch, 700c 64 - 74 inches tall
Inability to safely reach the handlebars and dismount the
bicycle may result in loss of control of the bicycle. If the
bicycle has a top tube on the frame, ensure there is one to
three inches of clearance between the rider and the top tube.
Improper setup or maintenance of the bicycle may result in
an unexpected movement, loss of control, and serious injury
or death.

Improperly adjusted seat height could aect the rider’s ability
to reach the handlebar and pedals may result in an unexpected
movement, loss of control, and serious injury or death. Follow
these guidelines when adjusng the seat height. Always
ensure the seat post minimum inseron marks are below the
seat clamp and cannot be seen. Ensure the seat clamp is
locked and the seat cannot move.
WARNING!
Seat Height and Handlebar Reach
❶Your legs should be almost completely straight when the
pedal is in the down most posion, just a slight bend in
the knee. Figure 1.2
Note: The rider’s feet may not touch the ground easily. If
this is the case the rider can simply move forward o the
seat to mount and dismount the bicycle or the seat can be
adjusted lower if the rider is uncomfortable with the height,
but note that riding is more dicult with the seat too low,
as the legs are in an unnatural posion.
Do not raise the seat so much the knees lock straight when
pedaling or you have to move forward o the seat to pedal.
This is unsafe and the bicycle cannot be controlled in this
condion.
❷You should be able to safely reach the handlebar with
your arms bent slightly (approximately 10 degrees) at
the elbow.

• Familiarize yourself with all the bicycle’s features before
riding. Pracce gear shis, braking, and the use of toe clips
and straps, if installed.
• Always ride defensively in a predictable, straight line. Never
ride against trac.
• Expect the unexpected (e.g., opening car doors or cars
backing out of concealed driveways).
• Take extra care at intersecons and when preparing to pass
other vehicles.
• Maintain a comfortable stopping distance from all other
riders, vehicles and objects. Safe braking distances and forces
are subject to the prevailing weather condions. Do not lock
up the brakes. When braking, always apply the rear brake
rst, then the front. The front brake is more powerful and if it
is not correctly applied, you may lose control and fall.
• Always use the correct hand signals to indicate turning
or stopping.
• Obey the trac laws (e.g., stopping at a red light or stop sign,
giving way to pedestrians).
• Wear proper riding are, reecve if possible, and avoid
open toe shoes.
• Do not use items that may restrict your hearing and vision.
• Do not carry packages or passengers that will interfere with
your visibility or control of the bicycle.
Road Condions
• Be aware of road condions. Concentrate on the path ahead.
Avoid pot holes, gravel, wet road markings, oil, curbs, speed
bumps, drain grates and other obstacles.
• Cross train tracks at a 90 degree angle or walk your bicycle
across.
Wet Weather
• When riding in wet weather always wear reecve clothing
and use safety lights to enhance visibility.
• Exercise extreme cauon when riding in wet condions.
• Ride at a slower speed. Turn corners gradually and avoid
sudden braking.
• Brake earlier, it will take a longer distance to stop.
• Pot holes and slippery surfaces such as line markings and train
tracks all become more hazardous when wet.
WARNING!
RIDING SAFETY
Riding the bicycle in unsafe condions (i.e. at night), in an unsafe
manner, or disregarding trac laws may result in an unexpected
movement, loss of control, and serious injury or death.

required to maintain pedaling speed.
• If you reach the lowest gear and are struggling, stand up on
your pedals. You will then obtain more power from each
pedal revoluon.
• On the descent, use the high gears to avoid rapid pedaling.
• Do not exceed a comfortable speed; maintain control and
take addional care.
• Braking will require addional distance. Iniate braking slowly
and earlier than usual.
Cornering Technique
• Brake slightly before cornering and prepare to lean your body
into the corner.
• Maintain the inside pedal at the 12 o’clock posion and
slightly point the inside knee in the direcon you are turning.
