MAINTENANCE
FLAT TIRE REPAIR (continued
)
1. Depress the tire valve to let all the air out of the tube, which will assist in removing the wheel
from the .
2. Remove the wheel from the using a wrench. Loosen the nuts counterclockwise
and make sure to remove the wheel retention clips on the front wheel. Be sure to remember
where all the spacers and washers belong. For rear tire removal you will also need to slip the
chain off the rear sprocket to remove the wheel. The chain must be properly reinstalled and re-
tensioned when reinstalling the rear wheel. Make certain the chain is properly positioned on both
front and rear sprockets before re-tightening rear wheel.
3. Remove one bead of the tire from the rim by grasping it at a point opposite the valve stem with
both hands and, at the same time, lifting and peeling one side of the tire off the rim. If the bead is
on too tight for you to unseat it with your hands use tire levers to lift the bead carefully over the
tire rim. Tire levers can be purchased at any local bike shop. Push the valve stem through the
wheel rim. Remove the inner tube.
4. Carefully check the outside and inside of the tire for the cause of the puncture and remove any
debris or damaging material from the inside or outside of the tire.
IF THE TIRE IS CUT, YOU MUST REPLACE THE TIRE TO PREVENT ANY SUDDEN
AND CATASTROPHIC FAILURE CAUSING LOSS OF CONTROL, SERIOUS INJURY OR DEATH.
Replacement parts are able to be purchased by calling the Greenwit Customer Service at 1-800

PATCHING A TUBE IS AN EMERGENCY REPAIR. CARELESS PATCHING OR APPLYING
SEVERAL PATCHES CAN SERIOUSLY WEAKEN THE TUBE, RESULTING IN POSSIBLE TUBE FAILURE,
WHICH COULD CAUSE YOU TO LOOSE CONTROL AND FALL. REPLACE A PATCHED TUBE AS
SOON AS POSSIBLE.
5. Reinstall the tire and tube. Slip one tire bead over the rim. Inset the tube valve through its hold
in the rim. Feed the tube carefully into the cavity of the tire. Inflate the tube just enough to give it
some shape. Starting at the valve stem and working around both sides of the rim to the side
opposite the valve stem, use your thumbs to push and seat the other bead of the tire inside the
rim. Be careful not to pinch the tube between the tire bead and the wheel rim. If you have trouble
getting the last few inches of bead over the edge of the rim with thumb pressure, use a tire lever
and be careful not to pinch the tube.
IF YOU USE A SCREWDRIVER OR ANY TOOL OTHER THAN A TIRE LEVER, YOU ARE
LIKELY TO PUNCTURE THE TUBE.
6. Check to make sure that the tire is evenly seated around both sides of the rim and that the tube
is inside the tire beads. Push the valve stem into the tire to make sure that its base is seated within
the tire's beads. Inflate the tube slowly to the recommended pressure on the tire sidewall, all the
while checking to make sure that the tire beads stay seated in the rim. Replace the valve cap.
