FLAT TIRE
If you get a flat tire, remove the wheel and 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 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 puncture cause and remove it. If the tire has a cut, line the inside of the tire in the area of the
cut with tape, a spare patch, a piece of an inner tube, or a dollar bill-whatever will keep the cut from
pinching the inner tube. 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 tire’s cavity. Inflate the tube just enough to give it some
shape. Start at the valve stem, use your thumbs to seat the tire bead inside the rim, and work your
way around both sides 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 inched
of bead over the edge of the rim with thumb pressure, use a tire lever and be careful not
to pinch the tube.
CAUTION
Using any tool other tool than a tire lever will likely 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 ensure 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 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 riding, you will have to ride 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 BRAKES OR THE FRAME. RIDING WITH A BROKEN
SPOKE CAN CAUSE YOU TO LOSE CONTROL AND FALL.
Twist the broken spoke around the spoke nest; it will keep it from flopping around and getting
caught between the wheel and the frame. Spin the wheel to see if the rim clears the brake pads.
If the wheel does not turn, try turning the brake cable adjusting barrel(s) clockwise to slacken the
cable and open up the brakes. If the wheel still won’t turn, open the brake’s quick release and
secure any loose as best you can. Walk the E-Bike, or if you must, ride it with extreme caution
because you now have only one working brake.
