Setup and Installation
Follow these steps to properly install your BAFANG electric bike battery:
Battery Holder Installation
The battery holder (mounting bracket) needs to be securely attached to your bike frame. Ensure your bike frame has the appropriate mounting points. The battery holder typically uses the water bottle cage mounts on the downtube.
Image: Visual guide demonstrating the three steps for installing the battery holder onto an electric bike frame.
- Step 1: Prepare Mounting Area - Identify the mounting holes on your bike frame, typically on the downtube. Ensure the area is clean and free of obstructions.
- Step 2: Attach Battery Holder - Align the battery holder with the mounting holes on your bike frame. Secure it using appropriate screws (not included, typically provided with the bike frame or conversion kit). Ensure it is firmly tightened.
- Step 3: Slide Battery On - Once the holder is secure, align the battery with the rails on the holder and slide it into place until it clicks and locks. Use the key to secure the battery to the holder.
Note: There are four holes in the bottom bracket of the product. If you intend to use it as a spare battery, please check the shape of the bottom of the battery to see if it is suitable for your original bracket.
