SpeedBox for Shimano E8000 is a process control module which increases the maximum speed of your electric bike from 25 km/h to 50 km/h. The display will only present speeds at half their actual values.
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
If you prefer to have your lights on and the SpeedBox activated at the same time, then do not connect the red wire of the SpeedBox to your drive.
