3. Setup and Installation
The Bafang M630 motor is designed for relatively easy installation, sharing the same frame mount as the M620 motor. However, careful attention to component compatibility is crucial for optimal performance and longevity.
3.1 Motor Mounting
The M630 motor utilizes a standard mid-drive frame mount, similar to the M620 model. Ensure your bicycle frame is compatible with this mounting type.
Figure 3.1: M620 and M630 Mid Motors share the same frame mount.
3.2 Electrical Connections
Identify the various connection points on the motor for proper wiring. Refer to the diagram below for common connection labels:

3.3 Drivetrain Compatibility
The motor is capable of producing significant torque (up to 230 Nm). To prevent damage and ensure smooth operation, it is highly recommended to match the motor with a compatible gear system.
Disadvantages of Incompatible Gear Systems:
- Without a 5-speed gearhub:
- Shifting gears under walk assistance can damage the chain and chainwheel, potentially leading to transmission failure.
- Using a rear derailleur with an incompatible setup may increase the frequency of failure and maintenance.
- With a single-speed freewheel:
- Riding without a derailleur can be strenuous or difficult to control speed, especially on hills or varied terrain.
- Higher gear ratios may be needed for strong winds or heavy loads, while lower ratios are better for downhill control.
- A single-speed freewheel limits performance and adaptability.

4. Operating Instructions
The Bafang M630 motor is designed to provide an intuitive and comfortable cycling experience, especially when paired with a compatible HMI display and gear system.
4.1 HMI Display and Gear Shifting
For optimal control and a smooth ride, integrate the M630 motor with a suitable HMI display (e.g., C010) and a compatible gear hub (e.g., G500A). The HMI display will show the current gear level, allowing for intuitive and smooth gear shifts.

4.2 Power Modes and Assistance Levels
Consult your specific HMI display manual for details on how to select different power modes and assistance levels. Typically, these systems allow you to adjust the motor's output to match your riding conditions and desired effort.
5. Maintenance
Regular maintenance ensures the longevity and reliable performance of your Bafang M630 motor kit.
- Regular Cleaning: Keep the motor and surrounding components clean from dirt, dust, and debris. Use a damp cloth for cleaning; avoid high-pressure washing directly on electrical components.
- Cable Inspection: Periodically check all electrical cables and connectors for signs of wear, fraying, or corrosion. Ensure all connections are secure.
- Fastener Check: Verify that all mounting bolts and fasteners for the motor and associated components are tightened to the manufacturer's specifications.
- Drivetrain Maintenance: Maintain your bicycle's chain, chainwheel, and freewheel/gearhub according to their respective manuals. Proper lubrication and adjustment are crucial, especially given the motor's high torque output.
- Professional Inspection: For complex issues or annual checks, it is recommended to have the motor system inspected by a qualified e-bike technician.
6. Troubleshooting
This section provides guidance on common issues you might encounter with your Bafang M630 motor kit.
