SpeedBox for Shimano E8000 Di2 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 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.
