At this point you are ready to loosen the axle nuts (15mm). Take out the upper bolt (5mm allen & 10 mm wrench) that holds the motor plate to the frame. Next, loosen the lower motor adjustment nuts (10mm wrench) at the front lower part of the motor plate, all the way. Shift the gears so the chain is in top gear (the smallest gear on the gear cluster).
This will allow the brake to open up enough to let the wheel and tire come through the brake pads. To do this you might have to loosen the ferrule at the brake handle or cable attachment screw on the brake itself. They will also have flats ground on the axle that will need to be lined up correctly when reinstalling the wheel.įirst, unhook the brake cable at the noodle (the 90 degree bend) and stirrup. Most have a plug, but some will require a bit more work. On a bike with a front or rear hub motor, there are some wires that will need to be disconnected before you can remove it from your bike. On a bike like that, the rear tire fix is no different that you are used to. Some E-bikes have a hub motor on the front. Fixing the front tire is the same as a normal bike. It has an external motor on the back of the bike. Inflate to the correct pressure and give the whole thing the one-over before you reinstall in on your bike. After inflating it a small amount, check the beading of the tire on the sidewall to make sure it is centered on the rim so the tire will turn true. Look for any other sharp edges before you put the tube and tire back on. Broken or loose spokes can punch a hole in your tube. Check the rim strip to make sure it covers all the spoke nipples on the inside of the rim. Don’t forget to check the inside of your tire for the thorn that caused the flat.
