The basic SpeedBox 1.1 upgrade kit is designed for electric bikes with Bafang motors. This kit allows doubling the speed limit of an e-bike from 25 km/h to 50 km/h. After installation, the actual speed is displayed at half the value on the screen, which also shows the distance and other aspects of the ride.
