the bicycle. Have the frame inspected by a qualified professional at a bicycle service shop before
riding the bicycle again.
NOTE:
Have a bicycle service shop make any repairs or adjustments for which you do not have the
correct tools or if the instructions in this manual or any "Special Instructions" are not sufficient for you.
REAR WHEEL/CHAIN ADJUSTMENT
Maintenance:
The chain must be at the correct tightness. If too
tight, the bicycle will be difficult to pedal. If too loose, the chain can
come off the sprockets.
WARNING: The chain must remain on the sprockets. If the
chain comes off the sprockets, the bike will not operate.
When the chain (1) is at the correct tightness, you can pull it one-half
inch (2) away from a straightedge (3) as shown.
TIRES
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.
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 innate the inner tubes. An
unregulated hose can suddenly over innate 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.
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 sealing and the pressure, until you reach the
correct inflation pressure as indicated on the tire sidewall.
Replace worn or defective tires and
inner tubes.
WHEELS
Wheel Inspection
It is most important that wheels are kept in top condition. Properly maintaining your bicycle's wheels
will help braking performance and stability when riding. Be aware of the following potential problems:
Dirty or greasy rims:
Caution:
These can render your brakes ineffective. Do not clean them with oily or greasy materials.
When cleaning, use a clean rage or wash with soapy water, rinse and air dry. Don't ride while they're
wet. When lubricating your bicycle, don't get oil on the rim braking surfaces.
Wheels not straight:
Lift each wheel off the ground and spin them to see if they are crooked or out of round. If wheels are
not straight, they will need to be adjusted. This is quite difficult and is best left to a bicycle specialist.
Broken or loose spokes:
Check that all spokes are tight and that none are missing or damaged.
Caution:
Such damage can result in severe instability and possibly an accident if not corrected. Again,
bicycle specialist best handles spoke repairs.
Loose hub bearings:
Lift each wheel off the ground and try to move the wheel from side to side.
Caution:
If there is movement between the axle and the hub, do not ride the bicycle. Adjustment is
required.
