Bafang M620 vs M560: Choosing the Right Mid-Drive Motor
If you're planning a high-torque mid-drive build, two Bafang motors dominate the conversation: the M560 and the M620 (often called the Ultra). They look similar, but they suit different goals. Here's how to choose.
The quick verdict
The M620/Ultra is the higher-output, higher-torque platform — the go-to when maximum power and climbing ability matter most. The M560 is a capable, efficient mid-drive that pairs well with builds where balance and value are the priority. Your choice comes down to how much power you actually need and how you tune the rest of the system.
Torque and power
The M620 is built to make more torque, which translates to stronger acceleration and better performance on steep terrain under load. The M560 delivers strong real-world performance too, but the Ultra has more headroom when you push voltage and current up.
Controllers: CAN vs UART
Both platforms are shaped heavily by their controller and firmware. The communication protocol — CAN vs UART — affects tuning options, display compatibility and how much of the motor's potential you can access. We cover this in depth in our Bafang Ultra M620/G510 controller guide, including the difference between 48V and 52V setups.
Putting it together: 2000W power
Either motor really comes alive as part of a properly specced high-power system. To see what a modern setup delivers, read our new 2000W power system overview — and if you're converting a bike yourself, our 2000W mid-drive conversion kit guide walks through matching the motor, battery and controller so the whole package works together.
Which should you choose?
- Choose the M620/Ultra if you want the most torque and power and plan to run a higher-voltage, high-current system.
- Choose the M560 if you want a strong, efficient mid-drive for a more balanced build.
Whatever you pick, the motor is only as good as the controller, battery and drivetrain around it — matching the whole system is what separates a good build from a great one.
