Standard or +E-Tube Port variant?

This product plugs into the motor's E-Tube port, so the e-bike motor needs one free E-Tube port. If your motor has a free port, choose the standard variant.
If you don't have a free E-Tube port, choose the +E-Tube Port variant. These are usually e-bikes with a Di2 electronic gear shifting system or with a tube integrated Satellite System ON/OFF Switch (EW-SW100, EW-SW300).

Compatibility

Shimano motors: EP8, EP8 RS

Also compatible with: Giant Revolt (up to 35 km/h)

Not compatible with Shimano motors: EP801, EP6

Tuning control

The tuning chip is controlled with the LIGHT button. When the lights are turned off, SpeedBox is activated.
If you want the tuning to be active at all times, regardless of the lights status, connect the fork terminal from SpeedBox to the screw terminal marked "-". If your e-bike has no lights function, SpeedBox will be activated at all times.

During the ride the display shows real values up to a speed of 23 km/h. If you want to see the correct speed and all riding data throughout the ride, we recommend the B.Tuning version, which shows real values in the SpeedBox Connect app right on your phone's display.

SpeedBox is intended for off-road use only and you use it at your own risk.
The manufacturer is not liable for damage caused by illegal or improper use.
Installation may also void your e-bike warranty.
For your safety, use appropriate protective gear and ride with maximum caution.
