Speedbox for Shimano E8000, E7000, E6100 & E5000

SpeedBox for Shimano E8000, E7000, E6100 & E5000 

This is a processor-controlled tuning tool especially for electric bikes with Shimano STEPS E8000, E7000, E6100 & E5000 drive systems. It doubles the maximum engine support from 25 km/h to 50 km/h (about 32 mph) – that means, you can drive twice as fast with full engine support!
 
If the light function of your Shimano STEPS E bike has been unlocked, you can easily switch the installed SpeedBox on or off using the light buttons (Light On = SpeedBox Off / Light Off = SpeedBox On). If the light function of your E Bike has not been unlocked, the SpeedBox is always active when the bike is switched on. By the way, you can have the light function of the bike unlocked at any time at your E Bike dealer or in a bicycle repair shop with the appropriate equipment (Shimano diagnostic devices)..
 
Important: When in use, the actual speed will appear on your display up to 22 km/h. Then the speed indicator gets stabilized and keeps on showing the same value even at higher speeds. The motor’s electric assistance switches off when reaching 50 km/h.

Not compatible with Di2!
