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 1.2 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 1.2 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's E-Tube port. It is therefore necessary that the e-bike motor in which you are going to install the new version of SpeedBox for Shimano has one free E-Tube port. In case you do not have a free E-Tube port in the motor, please select “+E-Tube Port” variant.

E-bikes, which do not have a free E-Tube port, are usually those with a Di2 electronic gear shifting system, with a tube integrated Satellite System ON/OFF Switch (EW-SW100, EW-SW300), or all e-bikes with E5000 motor.

How does SpeedBox 1.2 work?
This tuning chip can also be easily controlled with a LIGHT button. If the lights are turned off, SpeedBox is activated. The chip can be deactivated by turning on the lights. If you want to use tuning independently of the lights, do not connect the red wire during installation, like that the tuning will be always activated. If you do not have lights on your e-bike, SpeedBox 1.2 will also be activated at all times.

Important Safety & Legal Warning:

Performance Modification: The SpeedBox tuning chip is designed to update and modify your e-bike’s performance settings—altering speed limits and acceleration curves from the original factory configuration.

Firmware Updates Risk: Important: Updating your bike’s firmware while the chip is installed can potentially render the chip inoperable. The update process may conflict with the chip’s modified settings, which could permanently “kill” the chip. To avoid this, always remove the chip or consult with a qualified technician before performing any firmware updates.
