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 pedalling frequency.

For the older types of e-bikes with Shimano motor, our original tuning chip SpeedBox 1.0 for Shimano E6000 remains on sale. SpeedBox 1.2 for Shimano (E8000, E7000, E6100) and SpeedBox 1.3 for Shimano (EP8) are successors to the original tuning chips, which have been redesigned from the ground up. These chips completely eliminate the speed limit of 25 km/h. When in use, the display shows the actual speed up to 23 km/h, then the displayed speed fluctuates around this value.

Do you want something even cooler? Check out our SpeedBox 1.2 B.Tuning for Shimano (E8000, E7000, E6100) and SpeedBox 1.3 B.Tuning for Shimano (EP8) models. These tuning chips not only allow you to adjust the speed limit, but are also designed to pair your e-bike with a smartphone.
