Step 1
Remove the bike tire from rim
If you’re not sure how to take the wheels off your bike, check your owner’s manual or visit your local bike shop and ask someone on staff to show you how. Do this before you have a flat so you’ll be prepared.
In general, here’s how to do it:
Release the brake and loosen the axle nut so you can remove the wheel. Most bikes have a quick-release mechanism on the brakes and a quick-release lever on the axle. Removing the front wheel should be straightforward, but the rear wheel may take some maneuvering so the bike’s cassette clears the chain.
Changing an electric bike tire is similar to changing a normal bicycle tire. However, if your ebike has a hub motor instead of a mid-drive motor, check your owner’s manual to determine how to disconnect it.
After removing the wheel from the bike, take one edge, or bead, of the tire off the rim so you can remove the damaged tube. Pry under the tire bead with one of the tire levers and hook it to a spoke. Move over four to six inches and insert the other tire lever. Pry it down and slide it along the rim to release the tire.
Pull out the tube. (If the tire has a Presta valve, you’ll need to remove the nut on the stem.) Then remove the tire completely from the rim, put it around your neck like a necklace and turn it inside out while running your fingers along the inside to feel for sharp objects. Be careful, though — there could be metal or glass embedded in the tire.

Types of bike tire valves
When you go to buy a new tube, take the old tube with you and match the valve. Presta valves have a nut on a threaded shaft that seals the air in and must be loosened to inflate the tube. You’ll need a pump or tire inflator adapter that’s compatible with a Presta valve to inflate these tubes.
If you have Presta valves on your bike, keep a Presta-to-Schrader adapter with you at all times. That way you can use a gas-station air pump to inflate your tires.
