Removing Electric Bike Freewheels: A Step-By-Step Guide

Removing the freewheel from an electric bike can be a challenging task, especially if you don't have the right tools. The process typically involves removing the rear wheel, engaging a removal tool into the splines/notches, and turning it counterclockwise with a wrench. However, some electric bikes may not have bolts on the freewheels, making the process even more complicated. In such cases, you may need to drill out the freewheel or use a gear puller for removal. It's important to note that different models of freewheels may require specific tools and techniques, so it's always best to consult a professional or refer to the manufacturer's instructions before attempting any repairs.

Removing the rear wheel

First, mount the bike securely in a repair stand. This will ensure that the bike stays stable and doesn't move around while you're working on it. Once the bike is securely mounted, remove the quick-release skewer from the rear wheel. This will allow you to access the freewheel and start the removal process.

Next, you'll need to engage the appropriate tool into the splines or notches of the freewheel. This could be a standard Shimano freewheel remover, or you might need to drill it out to just over 12mm (or 14mm for some axles). Make sure the tool is securely engaged before proceeding.

Now, reinstall the quick-release skewer and snug the skewer nut against the removal tool. The skewer acts as a retaining device for the removal tool, ensuring that it stays in place while you apply force to remove the freewheel.

At this point, you're ready to start turning the removal tool. Use a large adjustable wrench, a 1" socket with a handle, or another appropriate wrench to turn the removal tool counterclockwise. It will typically require some force to turn the freewheel, so make sure you have a good grip on the tool and apply steady pressure. Turn the remover only one full revolution counterclockwise.

Finally, loosen and remove the skewer before continuing to remove the freewheel. With the skewer out of the way, you can now lift the freewheel off the hub. It's important to note that some freewheels may have a lockring holding the cogs in place, so be sure to check for this before attempting to lift the freewheel off.

By following these steps, you can safely and effectively remove the rear wheel of your electric bike. Remember to take your time, use the appropriate tools, and always make sure the bike is securely mounted before beginning any work.

Using a freewheel removal tool

To remove an electric bike freewheel, you will need a freewheel removal tool. If you have a standard Shimano freewheel, you will need to drill it out to just over 12mm (14mm for some axles). You can then use a big wrench on the freewheel tool to rotate it counterclockwise to remove the freewheel non-destructively. You could also use a hammer and drift on the gears, but this is not recommended unless absolutely necessary.

If you do not have a standard Shimano freewheel, you may need a different tool. Begin by threading the cogs clockwise by hand until the freewheel feels fully threaded. If you encounter a great deal of resistance, remove and attempt better thread alignment. Use a chain whip to rotate the cogs clockwise until snug. This will fully seat the freewheel against the hub. Alternatively, install the wheel into the bike, apply the rear brake, and push down on the pedal.

If you are using a freewheel removal tool, mount the bike in a repair stand and remove the rear wheel. Remove the quick-release skewer. Engage the appropriate tool into the splines/notches. Reinstall the quick-release skewer. Install and snug skewer nut against removal tool. The skewer acts as a retaining device for the removal tool. Turn the removal tool counterclockwise using a large adjustable wrench, 1″ socket with handle, or other appropriate wrench. It will typically require some force to turn the freewheel. Turn the remover only 1 full revolution counterclockwise. Loosen and remove the skewer before continuing to remove the freewheel. Continue to turn the remover counterclockwise until the freewheel is unthreaded from the hub. Lift the freewheel from the hub.

Using a wrench to turn the removal tool counterclockwise

To remove an electric bike freewheel, you will need to use a wrench to turn the removal tool counterclockwise. This will require some force, so make sure you have a firm grip on the wrench. Turn the remover only one full revolution counterclockwise.

You may need to engage the appropriate tool into the splines/notches before turning the removal tool. The skewer acts as a retaining device for the removal tool, so it is important to ensure that it is installed correctly.

If you are using a standard Shimano freewheel remover, you will need to drill it out to just over 12mm (14mm for some axles). This will allow you to use a big wrench to rotate the freewheel tool counterclockwise and remove the freewheel non-destructively.

It is important to note that if you encounter a great deal of resistance when turning the removal tool, you should remove it and attempt better thread alignment. You can do this by using a chain whip to rotate the cogs clockwise until they are snug.

Begin threading the cogs clockwise by hand until the freewheel feels fully threaded. If you encounter a great deal of resistance, remove the cogs and attempt better thread alignment. Use a chain whip to rotate the cogs clockwise until snug. This will fully seat the freewheel against the hub. You can also install the wheel into the bike, apply the rear brake, and push down on the pedal. If you are using a new freewheel or wheel, check all adjustments of the rear derailleur. Some thread-on freewheels use a lockring to hold the cogs to the freewheel body.

Once the freewheel is fully seated, you can continue to turn the remover counterclockwise until the freewheel is unthreaded from the hub. Lift the freewheel from the hub. Heavily lubricate the mounting threads of the freewheel using grease or an anti-seize compound.

Lubricating the mounting threads of the freewheel

To lubricate the mounting threads of the freewheel, you will need to use grease or an anti-seize compound. This is an important step to ensure the freewheel is properly installed and functions smoothly.

Begin by mounting the bike in a repair stand and removing the rear wheel. This will give you access to the freewheel and its mounting threads. With the wheel removed, you can then apply the lubricant of your choice to the mounting threads. Make sure to apply it generously, as per the instructions provided by Park Tool.

There are a few different methods to remove the freewheel, depending on the tools you have available and the specific design of your electric bike. One common method involves using a freewheel removal tool, which you can engage into the splines or notches of the freewheel. You may need to drill out the removal tool to the appropriate size, as mentioned in the Endless Sphere forum. Reinstall the quick-release skewer and snug the skewer nut against the removal tool. This will act as a retaining device.

Turn the removal tool counterclockwise using a large adjustable wrench or a similar tool. You may need to apply some force to turn the freewheel. Continue turning the remover counterclockwise until the freewheel is unthreaded from the hub. At this point, you can lift the freewheel from the hub.

It is important to note that some freewheels may use a lockring to hold the cogs in place. If you encounter significant resistance when threading the cogs, remove them and attempt better thread alignment. You can also use a chain whip to rotate the cogs clockwise until they are snug, fully seating the freewheel against the hub.
