SpeedBox2 for Bosch is revolutionary processor-controlled module what removes the speed limiter of your electric bike. Display shows real values! Values such as maximum speed, average speed, daily mileage and range are displayed correctly

The SpeedBox2 is activated by briefly pressing the WALK button located on the front of the control panel. After pressing this button, the current speed of 9.9 km/h is displayed on the control panel for about 3 seconds. This means that the SpeedBox2 is activated, and the motor support of the electric bike now works up to a speed of 99 km/h. When the WALK is pressed again, the current speed of 2.5 km/h is displayed. This means that the SpeedBox2 is deactivated, and everything works as it would if it weren't installed. The motor support of the electric bike now works up to a speed of 25 km/h.

I have an old bike Classic line with the Intuvia display (was HMI 'upgraded' to Intuvia display).

Is the SB2 will work on this configuration ? in other words, is the box dependant of the display type or engine ?

Do you have a box to recomand for the old Classic line ?

Thanks in advance for your comments.

Is a software update to latest 2018 Bosch CX Version (eMTB mode) with an installed Speedbox2 possible?

Jiří Voldán (Obchoďák) Administrator 28. 11. 2017 | 21:10

Yes it is. SpeedBox works fine with eMTB update.

How does Speedbox 2 turn on, if the "walk" button is deactivated ? It is possible to turn it on ?

Jiří Voldán (Obchoďák) Administrator 23. 11. 2017 | 03:29

Hello Aaron.

Yes it is possible.

We noticed there are some bikes with deactivated WALK button.

So we came up with different way how to turn the SpeedBox on.

You can activated SpeedBox by pressing of buttons (+ - + -) or (- + - +) quickly.

I have seen a press release that Bosch are buying a company called COBI which makes an adapter and Android/iOS app to replace the Nyon and Intuvia computers.

Has the Speedbox 2 been tested with the COBI system at all? Do you think there will be compatibility?
