SpeedBox 3.0 B.Tuning Bluetooth Tuning Chip for Bosch

SpeedBox 3.0 B.Tuning is the Bluetooth version of SpeedBox 3.0 for Bosch. It deactivates the factory speed limiter, allows a speed limit to be set, and keeps actual values on the e-bike display.

Paired with the SpeedBox Connect app, it shows current ride data and trip parameters on your phone, stores individual trips for comparison, and adds tuning control, motor lock and motor diagnostics. The chip also works without the app.
