2. Compatibility and Pre-Installation Checks
Before beginning installation, ensure your bicycle is compatible with the mid-drive motor kit. The kit is designed for standard bottom bracket sizes.
2.1 Bottom Bracket Compatibility
The mid-drive motor kit is compatible with bicycle bottom brackets of 68-73mm, 100mm, or 120mm. Measure your bicycle's bottom bracket length to select the correct motor size.
Image: Diagram illustrating how to measure a bicycle's bottom bracket and showing the compatibility of BAFANG mid-drive motors with 68mm, 100mm, and 120mm bottom bracket sizes.
- 68mm: Suitable for 68-73mm bottom bracket bikes.
- 100mm: For 90-100mm bottom bracket bikes, includes a 10mm washer.
- 120mm: For 110-120mm bottom bracket bikes, includes a 10mm washer.
If your bicycle's bottom bracket is larger than 73mm but smaller than 100mm, or larger than 100mm but smaller than 120mm, spacers may be required. For bottom brackets larger than 73mm, consider a 1000W motor as 500W/750W motors are typically for 68-73mm.
2.2 Chain Wheel Size
Different chain wheel sizes are available depending on your motor model and preference.
