How to install the Bafang mid-drive motor

Follow these steps to install the Bafang BBS02B mid-drive motor on your bike:

Step 1: Remove the Pedals and Bottom Bracket

Using the appropriate wrenches and bottom bracket tool, remove the pedals and bottom bracket from your bike. This will allow you to access the bottom bracket shell, where the Bafang motor will be installed.

Step 2: Install the Bafang Motor

Follow the manufacturer's instructions to install the Bafang motor onto the bottom bracket of your bike. Use the appropriate torque when tightening the bolts. Make sure to position the ebike motor correctly, and use spacers if required to prevent it from touching the chainstay.

Step 3: Install the Chainring

If the chainring is not already installed in the Bafang kit, use the appropriate bolts to attach it to the motor. Make sure it's tightened properly and aligned with the chain.

Step 4: Install the Cranks

Attach the left and right Bafang cranks to the motor crank using the bolts provided in the Bafang BBS02B mid-drive motor kit, ensuring they are tightened appropriately.

Step 5: Install the Wiring

Run the wiring from the Bafang motor to the controller and battery, following the manufacturer's instructions closely. Use electrical tape or heat shrink to secure the wiring in place as needed to ensure proper installation.

Step 6: Install the Battery

It's important to follow the manufacturer's instructions when attaching the battery to your bike's frame. Be sure to position it securely in a safe location to prevent it from getting damaged or causing any harm.

Step 7: Test the Motor

Test the motor to ensure it's working properly. Check the torque sensor and throttle (if your ebike conversion kit includes one). If there are any issues, troubleshoot them following the manufacturer's instructions.

Step 8: Adjust the Brakes and Gears

Adjust the brakes and gears on your bike as necessary. The Bafang motor may affect how these components work, so it's important to make sure they're adjusted properly.

Now that you have finished all the steps, the Bafang BBS02B mid-drive motor should be successfully installed on your bicycle. Have fun with your improved cycling experience, but don't forget to always follow the manufacturer's instructions carefully and take necessary safety measures when dealing with electrical components. Enjoy your new motor and ride safely!
