Changing an Ebike Tire tube

Here are the steps to change the tire tube on an ebike. Before you start you need to identify the type of motor you ebike has. To change the tire on a rear hub motor bike you first have to disconnect the electric cable that connects the motor to the motor controller for the bicycle.

1. Remove the wheel: To access the tire, you need to remove the wheel from the bike. Depending on the bike, you may need to release the brake calipers or the quick release lever to remove the wheel.
2. Remove the tire: Once the wheel is off, use a tire lever to pry the tire off the rim. Be careful not to damage the rim or spokes.
3. Remove the inner tube: Once the tire is off, remove the inner tube by pulling it out from one side of the tire.
4. Check for damage: Inspect the inside of the tire for any cuts, punctures, or other damage. If the tire is damaged, you may need to replace it.
5. Replace the inner tube: Insert the new inner tube into the tire, taking care to ensure that it is properly positioned and not twisted.
6. Replace the tire: Put the tire back on the rim, being careful not to pinch the inner tube. Make sure the tire is properly seated and there are no wrinkles or bulges in the sidewall.
7. Inflate the tire: Use a pump to inflate the tire to the recommended pressure. Be sure to check the sidewalls of the tire and make sure there are no leaks.
8. Reinstall the wheel: Reinstall the wheel on the bike and tighten the quick release lever or brake calipers.

Note: Some electric bikes may have different tire and tube requirements. Before changing the tire tube, consult the owner’s manual for your specific bike for guidance.
