Service & Maintenance Schedule
fraying and discoloration are signs of stress-caused fatigue and indicate that a part is
at the end of its useful life and should be replaced.
Flat Tire
If you get a flat tire, remove the wheel. Depress the tire valve to let all the air out of
the tube. Remove one bead of the tire from the rim by grasping the tire at a point
opposite the valve stem with both hands lifting and peeling one side of the tire off
the rim. If the bead is too tight for you to unseat it with your hands, use tire levers to
lift the bead carefully over the tire rim. Push the valve stem through the wheel rim.
Remove the inner tube.
Carefully check the outside and inside of the tire for the cause of the puncture and
remove the cause if it is still there. If the tire is cut, line the inside of the tire in the
area of the cut with tape, a spare patch, a piece of inner tube, whatever will keep the
cut from pinching the inner tube.
Either patch the tube (Follow the instructions in your patch kit),or use a new tube.
Reinstall the tire and tube. Slip one tire bead over the rim. Insert the tube valve
through its hole 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 use your
thumbs to seat the tire bead inside the rim. Work your way around both side of the
wheel until the entire bead is seated in 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.
CAUTION:
If you use a screwdriver or any tool other than a tire lever, you are likely to puncture
the tube.
Check to make sure 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, all the while checking to make sure that the tire beads stay seated in the
rim. Replace the valve cap, and install the wheel onto the E-Bike.
WARNING:
Riding your E-Bike with a flat or under-inflated tire can damage the tire, tube and
E-Bike, and can cause you to lose control and fall.
Broken Spoke
A wheel with a loose or broken spoke is much weaker than a fully tensioned wheel.
If you break a spoke while on a ride, you will have to ride home much more slowly and
carefully because the weakened wheel could break additional spokes and become
useless.
WARNING:
A broken spoke seriously weakens the wheel and may cause it to wobble, striking the
