Service & Maintenance Schedule
a component's life cycle is exceeded, the component can suddenly and catastrophically
fail, causing serious injury or death to the rider. Scratches, cracks ,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.
