The SpeedBox 1.2 for Bafang (3-pin connector) is a debriding module designed for electric bikes equipped with Bafang Max Drive M300 and M400 motors with 3-pin connector. It removes the assistance limit at 25 km/h, offering smooth assistance up to 50 km/h. The module is activated by pressing the LIGHT button on the control console. The headlight symbol appears briefly, indicating that the SpeedBox is activated. To deactivate, simply press the LIGHT button again.
Installation is simple, thanks to color-coded connectors that do not require soldering. We recommend a 10 km ride before activating the module on a new bike.
