This is a basic tuning kit for e - bikes with Bafang motors. The SpeedBox 1.2 can double your e - bike's speed limit from 25 km/h to 50 km/h. While in use, your display will show real values up to 23 km/h and also details about your trip and other ride aspects. Activate the SpeedBox 1.2 on your e - bike's control unit. Press the LIGHT button, and soon the active lights icon will appear, allowing you to reach 50 km/h. Press the LIGHT button again to deactivate it. Attach the Light cable for Bafang to use the SpeedBox and your lights simultaneously. Installation is a breeze as the connectors are color - coded, and we've provided detailed instructions and videos for home installation. Disassembly is just as easy. If you're installing on a new bike, ride it for at least 1 km before activating the chip. Find detailed installation info here: text. Note that using modified e - bikes on public roads may be illegal in some countries. The manufacturer isn't responsible for damages.

It's compatible with Bafang Max Drive M300 and M400 but not with the SpeedBox App. When updating your e - bike's software, uninstall the SpeedBox first, update, and then reinstall it.
