Wheel Bearings
Lift each end of the bicycle off of the ground and slowly spin the raised wheel by hand. The
bearings are correctly adjusted if:
• The wheel spins freely and easily.
• The weight of the spoke reflector, when you put it toward the front or rear of the bicycle,
causes the wheel to spin back and forth several times.
• There is no side-to-side movement at the wheel rim when you push it to the side with light
force.
Lubrication
WARNING: Do not over lubricate. If oil gets on the wheel rims or the brake shoes,
it will reduce brake performance and a longer distance to stop the bicycle will be
necessary. Injury to the rider or to others can occur.
• The chain can throw excess oil onto the wheel rim. Wipe excess oil off the chain otherwise injury to
the rider or to others can occur.
• Keep all oil off the surfaces of the pedals where your feet rest otherwise injury to the rider or to
others can occur.
• Using soap and hot water, wash all oil off the wheel rims, brake shoes, pedals and the tires. Rinse
with clean water and dry completely before you ride the bicycle.
• Using a light machine oil (20W) and the following guidelines, lubricate the bicycle:
What When How
Brake Levers Every 6 months Put one drop of oil on the pivot point of each brake
lever.
Caliper Brakes Every 6 months Put one drop of oil on the pivot point of each caliper
brake.
