Three-Piece Cranks (on some models)
Maintenance
Both three-piece crank arms [1] were tightened to the spindle
[2] at the factory. After riding the bicycle the first few times,
make sure the crank arms have not loosened. If either crank
arm has loosened during this “break-in” period, have it
tightened by a bicycle service shop, because special tools are
necessary.
Frequently check the tightness of the crank arms. If loose,
have them tightened by a bicycle service shop.
CAUTION: If you ride the bicycle for a moderate
length of time with a loose crank arm, the spindle
will damage the crank arm.
WARNING: Do not ride or sit on the bicycle if either inner tube is under inflated. This can
damage the tire and inner tube. Do not use unregulated air hoses to inflate the inner tubes.
An unregulated hose can suddenly over inflate bicycle tires and cause them to burst.
Use a hand or a foot pump to inflate the inner tubes. Service station meter-regulated air hoses are
also acceptable. The correct inflation pressure is shown on the tire sidewall. If two inflation pressures
are on the tire sidewall, use the higher pressure for on-road riding and the lower pressure for off-road
riding. The lower pressure will provide better tire traction and a more comfortable ride.
Before adding air to any tire, make sure the edge of the tire (the bead) is the same distance from the
rim, all around the rim, on both sides of the tire. If the tire does not appear to be seated correctly,
release air from the inner tube until you can push the bead of the tire into the rim where necessary.
Add air slowly and stop frequently to check the tire seating and the pressure, until you reach the
correct inflation pressure.
Replace worn or defective tires and inner tubes.
Maintenance
Frequently check the tire inflation pressure because all tires lose air slowly over time. For extended
storage, keep the weight of the bicycle off the tires.
