From the ground up redesigned tuning chip for your e-bike with a Shimano motor – with a new design and completely new hardware and firmware.

The tuning chip SpeedBox 1.3 enables you to suppress the speed limiter on your electric bike. When in use, the actual speed will appear on your display up to 23 km/h.

If you want to see correct speed and all riding data during your ride, we recommend choosing SpeedBox 1.3 B.Tuning for Shimano - you can see the real values in our SpeedBox App – right on the display of your phone.

Compared to previous versions, this new product also plugs into the engine...
