With SpeedBox you won´t be limited to the speed of 25 km/h anymore. You can freely enjoy the maximum power of your electric bike, limited only by your pedaling frequency.

SpeedBox 3.0 for Bosch and SpeedBox 2.0 for Bosch are reliable tuning chips. What exactly does this mean? The speed limit of 25 km/h is completely eliminated with real values shown on the bike’s display.
