Step-by-Step Guide to Reattaching a Chain on Your Electric Bike

Riding an electric bike is a joy until you're halted by a slipped chain. But fear not, as putting a chain back on your e-bike is a task you can handle with just a bit of know-how and some patience.

Why Does a Chain Come Off an E-Bike?
Before diving into the solution, it's helpful to understand why chains come off. It could be due to improper tension, misalignment, a collision, or simply wear and tear.

Tools You May Need:

1. Gloves to keep hands clean


2. Rag or cloth for cleaning


3. Chain tool (optional)

Steps to Put the Chain Back on an Electric Bike:

1. Turn Off the E-Bike: Safety first! Ensure your e-bike is switched off to prevent any accidental engagement of the motor.


2. Position the Bike: Flip the e-bike upside down for easier access to the chain and drivetrain or put it on a stand if available.


3. Inspect the Chain: Before you put the chain back on, inspect it for any damage or kinks. If it's damaged, it may need replacing.


4. Locate the Derailleur: The derailleur is the mechanism that shifts the chain between gears. It's crucial for maintaining proper chain tension.


5. Reattach the Chain: Hold the chain with your hands and loop it over the rear cassette (the set of gears nearest the back wheel). Then, guide the chain through the derailleur, ensuring it is on the correct track.


6. Pedal Forward Slowly: Using your hand, pedal forward slowly to move the chain back onto the front chainring. Ensure the bike is in a low gear to make this easier.


7. Check the Tension: Once the chain is on, check the tension by pushing on the chain slightly. It should have a little give, but not much.


8. Test the Repair: Flip the bike back to its upright position and turn it on. Then, pedal manually at first to ensure the chain is running smoothly.

Tips to Avoid Future Slippage:

• Regularly clean and lubricate your chain to minimize wear.


• Ensure your derailleur is properly adjusted.


• Periodically inspect the chain tension and make adjustments as necessary.

By following these steps, you'll be back on the road in no time. Remember, regular maintenance can help prevent chain issues in the future, enhancing your e-bike's performance and longevity.
