THE SpeedBox 3.0 for Bafang M300 / M400 (3 pin connector) is a release module intended for electric bikes equipped with Bafang Max Drive M300 or M400 motors with 3-pin speed sensor. It allows the assistance limit to be removed at 25 km/h, offering the possibility of driving at much higher speeds (depending on physical condition, wheels, slope, etc.).
Activation and deactivation is done via the button LIGHT of the bike or via the key combination ↑↓↑↓. When the SpeedBox is activated, the screen briefly displays 99 km/h to signal that the restriction is lifted. To return to the normal limit, simply repeat the operation.
