New generation tuning chip with Bluetooth and mobile app for your e-bike. Our most powerful and versatile product.

This new product brings a unique connection of e-bike and mobile phone. The SpeedBox B.Tuning chip is a top-notch product perfectly optimized for the most powerful ride and experience. It suppresses the speed limiter so you can enjoy your ride at unlimited speed.  Thanks to SpeedBox App mobile application you can monitor and store all the parameters of your trip on the display of your phone in any place, anytime.

How does SpeedBox B.Tuning work?

Our newest chip features an easy and user-friendly control unit. The tuning kit can be activated directly from the mobile application or on your bike’s display.  After pressing the WALK button, a value of 9.9 km/h (6.2 mph) is displayed and from now on you will be able to ride at a speed of 40 km/h, 50 km/h or even more than 60 km/h.

To deactivate the tuning kit, press the WALK button again. The value of 2.5 km/h (1.6 mph) will appear on your display and the speed limit will reset to 25 km/h. Your e-bike will then work the same as before installation of the chip.

SpeedBox was also designed for e-bikes that do not have a classic control unit with Walk button. In this case you can just use the combination of + - + -  buttons and SpeedBox will be activated. You can easily deactivate SpeedBox in the same way.

SpeedBox App for SpeedBox B.Tuning

SpeedBox App is an application specially designed for SpeedBox B.Tuning, which uses Bluetooth technology to connect your e-bike to your mobile application. After downloading the application and connecting your mobile phone to your e-bike you will see current data and trip parameters displayed on your phone. Individual trips can be stored so that the results can be compared with friends and together they can monitor their performance. So just enjoy the ride and leave checking the parameters for later!

What is the maximum speed after installing the SpeedBox B - Tunning ? 32 km/h or 45 km/h ?
Kind regards,

Veronika Pinkasová (Sales Manager)Administrator |

Hello, the maximum speed depends on a pedalling rate and on the external conditions. You can reach about 50-60 km/h but it's physically exigent, so it's not for a long time ride. Rgeards.


Love my speedbox B tuning, but is there anyway to grab/export the save file and view it in notepad/excel etc?
Many thanks!

Nicholas Yanarella

Will this work on the new trek domane+ quick is limmited to 28mph?


I will also lift the question from Mikael:
It would be very nice if I were able to put a new speed limit e.g. 35 km/h (via the app) where the motor would stop the support (like the redped, volspeed) Is that a function we will see in SpeedBox B in the near future?

This would be a great feature.


What kind of a speed can you expect with a Bosch Active Line Plus motor?
