The SpeedBox 1.0 B.Tuning is a tuning chip for electric bikes with Bosch Gen4 and Smart System motors. It connects to the SpeedBox app via Bluetooth and removes the speed limiter. It can be activated via the app or the bike’s control unit using WALK mode or the +-+- button combination.

The display shows the actual speed up to 22.2 km/h; above that, it displays the speed using the last two digits of the reading. The app shows the actual speed and other ride data. To activate the functions, select the wheel circumference from the menu after starting the bike. When charging with the battery connected, the countdown continues in the background; if the battery is removed, the process must be completed after the ride.
