Learn to replace the inner tube and repair a flat tire on your QuietKat Electric Bike
- 
Tools Needed: - Tire irons
- Standard bicycle pump with a Schrader valve
 
- 
Removing the Wheel: - Loosen the bolts on your fixed axle or unthread your thru-axle, and remove the wheel.
 
- 
Deflating the Tube: - Locate the valve and press the valve in towards the tire while squeezing the tire to release any remaining air. This will ensure the tube is fully deflated.
 
- 
Removing the Tire: - Make sure the bead is completely separated from the rim by pressing the tire along the rim on both sides.
- Insert a tire iron (metal or plastic will work) in between the rim and the bead of the tire and start to peel the tire off the rim on one side.
- It's easiest to leave one side of the tire on the rim, but you can certainly separate the tire from the rim entirely.
 
- 
Taking Out the Inner Tube: - Locate the valve, push it up into the rim, reach in between the rim and tire, and grab the inner tube.
- Slowly pull the inner tube out of the tire and rim and discard the old tube.
 
- 
Preparing the New Tube: - Use a new tube, such as the Kenda Juggernaut tube. Replacement tubes can be purchased on our website.
- Pre-inflate the tube slightly for easier installation.
 
- 
Installing the New Tube: - Insert the new tube in between the tire, ensuring the tube is straight and not twisted around the rim.
- Start at the valve, work the tube into the tire, and align the valve with the rim hole.
 
- 
Putting the Tire Back On: - Start at the valve and work your way around, pressing the tire bead under the rim.
- Use your thumbs to push the tire bead back under the rim.
- For the last section, use a tire lever for added leverage if you are unable to get the last of the bead onto the rim with your thumbs alone.
 
- 
Inflating the Tire: - Inflate the tire to the recommended pressure:
- 18 pounds recommended (12-14 pounds for soft terrain, up to 22 pounds for hard pack or road).
