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. 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.

Hello, I've tried connecting this twice to my e8000 motor...with the same result WO11 error. Yes, I disconnected the battery, I made sure the connections were made...how do I get my money back?

Hello, I have the speedbox with the sigma sensor (for e8000), but when I start pedaling it displays both speeds (real and half) 4/8km then 5/10km then 6/12km, this cant be normal because when it reaches 12km (25real) cuts the motor.... is this because of the sensor? should I cut it and use the one on the bike (near the brake)?

Hi Dan. Where did you buy the SpeedBox? From us?


Is it possible to have the Speedbox turned on or off in any other way than using the lights control? I'd like to have the option of using lights with the speedbox on or off.


Focus Jam with E8000 (no di2). I bought a sensor and i got error message once installed : W011. I unplugged and plug again, same result. What can I do?

I don’t have the rear sensor. I used the original sensor located at the rear, almost at the disk position.

Hello Pierre. Please use force while connecting SpeedBox with speed sensor. I think there is a problem in contact between these two.


Hello,I have a Kola Pace S20, my sensor is located behind the brake disc. Is it possible to use the speedbox with the original sensor?
