SpeedBox for Shimano E8000, E7000, E6100 & E5000 is a process control module which increases the maximum speed of your electric bike from 25 km/h to 50 km/h.

If you do not have lights installed by a certified service technician,the tuning kit is always active from the moment you turn your bike on.

If you have lights on your ebike, which have been installed by a certified service technician, then you will be able to activate or deactivate your SpeedBox.

Lights on → SpeedBox is deactivated
Lights off → SpeedBox is activated

When the tuning device is active, the speed of the electric bike is correctly displayed up to a speed of 22 km/h. When speeds over 22 km/h are achieved the speed indicator constantly shows 22 km/h. The supplementary assistance of your electric bike switches off when you reach a speed of 50 km/h.

I am looking to unlock a YT Decoy CF Pro & a CF Pro Race both w/ e8000 motors...
The Race model includes Di2 the other does not, will the same SpeedBox not work in both bikes?

What is the difference between the non-Di2 & this from the SpeedBox's perspective?
