If you’re like most electric bike riders, you’ll eventually need to change a rear tube. It’s not a difficult task, but it does require a few specialized tools. In this article, we’ll walk you through the steps on how to change the rear tube on an electric bike. We’ll also provide some tips on how to avoid flats in the future.
First, you’ll need to gather a few tools. You’ll need a pair of tire levers, a new tube, and a patch kit. You may also want to have a pair of gloves on hand to protect your hands from the tire levers. Once you have your tools, you’re ready to get started.
To start, you’ll need to remove the rear wheel from the bike. To do this, simply flip the bike upside down and locate the two bolts that hold the wheel in place. Remove the bolts and then carefully lift the wheel off of the bike. Once the wheel is off, you can lay it down on the ground and begin changing the tube.
Disassembly of Rear Wheel
1. Remove the brake caliper
Using a 5mm Allen key, loosen the bolts that hold the brake caliper to the frame. Carefully remove the brake caliper and set it aside. Be careful not to damage the brake line.
2. Remove the wheel
Use a 15mm wrench to loosen the axle nuts on both sides of the wheel. Once the nuts are loose, you can pull the wheel straight out of the frame.
3. Remove the tube
The tube is held in place by a tire liner. To remove the tube from the liner:
1. Insert a tire lever between the tire and the liner. Pry the tire away from the liner enough to expose the valve stem.
2. Use a pair of pliers or a tube wrench to unscrew the valve core. Allow all the air to escape from the tube.
3. Use your fingers or a tire lever to carefully pull the tube out of the tire.

Tube Inspection and Removal
Preparation:
Prior to starting any maintenance, ensure the electric is powered off and the battery is disconnected. Gather the necessary tools, including a wrench, pliers, and a tire lever set.
Tube Inspection:
Inspect the rear tube thoroughly for any punctures or damage.Inflate the tube slightly and submerge it in a bucket of water to identify any leaks. If leaks are detected, replace the tube.
Tube Removal:
Start by loosening the nuts on the axle with a wrench. Use pliers to remove the axle bolt and spacer. Carefully lift the wheel off the axle.
Once the wheel is removed, remove the valve cap and use a tire lever to pry the tire bead away from the rim. Work your way around the tire, gradually prying it loose until you can lift it off the rim.
With the tire removed, you can access the tube. Grip the tube firmly and carefully pull it away from the rim. Be mindful not to damage the tube or the rim.
Detailed Instructions for Removing the Tube:
| Step | Action |
|---|---|
| 1 | Loosen the axle nuts. |
| 2 | Remove the axle bolt and spacer. |
| 3 | Lift the wheel off the axle. |
| 4 | Use a tire lever to pry the tire bead away from the rim, starting at the valve stem and working your way around. As you pry the bead loose, work the tire off the rim by rolling it away from the center. |
| 5 | Remove the tube by gripping it firmly and gently pulling it away from the rim. |
Once the tube is removed, inspect it for damage and replace it if necessary.
How To Change The Rear Tube On Electric
Changing the rear tube on an electric bike is a relatively simple task that can be completed in a few steps. Here’s a step-by-step guide to help you get the job done:
- Gather the necessary tools and materials. You will need a new rear tube, a tire lever, a patch kit, and a pump.
- Remove the rear wheel. To do this, you will need to locate the quick-release lever on the side of the bike frame. Once you have found the lever, open it and pull the wheel towards you to remove it.
- Remove the old tube. Once you have removed the rear wheel, you will need to remove the old tube. To do this, use the tire lever to pry the tire bead away from the rim. Once you have pryed the tire bead away, you can pull the old tube out of the tire.
- Install the new tube. Take the new tube and insert it into the tire. Make sure that the valve stem is lined up with the hole in the rim. Once you have inserted the new tube, you can use the tire lever to pry the tire bead back onto the rim.
- Inflate the tire. Once you have installed the new tube, you can inflate the tire. Be sure to inflate the tire to the recommended pressure, which can be found on the sidewall of the tire.
- Reinstall the rear wheel. Once you have inflated the tire, you can reinstall the rear wheel. To do this, simply slide the wheel into the frame and close the quick-release lever.
