bike back to the dealer for a checkup. Dealers typically suggest you bring the bike in for a
30-day checkup. Another way to judge when it’s time for the rst checkup is to bring the
bike in after three to ve hours of hard o-road use, or about 10 to 15 hours of on-road
or more casual o-road use. But if you think something is wrong with the bike, take it to
your dealer before riding it again.
Before every ride: Mechanical Safety Check (Section 7.A).
After every long or hard ride; if the bike has been exposed to water or grit; or at least
every 100 miles.
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. 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 dealer check it.
Lift the front wheel o the ground and swing it from side to side. Feel
smooth? If you feel any binding or roughness in the steering, you may have
a tight headset. Have your dealer check it.
Grab one pedal and rock it toward and away from the centerline of the bike;
then do the same with the other pedal. Anything feel loose? If so, have your
dealer check it.
Carefully check the electronic cables and cable housings. Any rust? Kinks?
Fraying? If so, have your 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 dealer check the wheel for tension and trueness.
Check the tires for excess wear, cuts, or bruises. Have your dealer replace
them, if necessary.
Check to make sure that all parts and accessories are still secure, and tight-
en any which are not.
Check the frame, particularly in the area around all frame joints: the handle-
bars, the stem, and the seatpost for any deep scratches, cracks, or discolor-
ation. 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. See also Appendix B.
Check the folding mechanism: If you feel a signicant amount of resistance
in the folding joint between the front and rear frame parts, please visit your
dealer for a full bike check.
Check the belt tension: Put pressure on the pedals, If you feel a jump in the
cog of the sprockets, it is necessary to adjust the tension of the belt. Visit
your local bike shop or dealer for a full bike check.
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 discoloration
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 specied
period of time by the manufacturer, this is no guarantee that the
