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!

Does this work with both the Bosch Active Line and the New Bosch Performance Speed Line? I have a bike with an active line and have a bike with a Performance Line Speed on order. I am wondering if this will work on both of them. I would like to be able to use it on my Active Line motor, and then remove it and use it on my Performance Line Speed motor when it arrives.


What type of water resistance does the speedbox have, It stayed in my pocket and accidentally went through the washing machine. I was about to sell mine since I changed bike which has a different motor and since I can't test it I wanted to know if it's fried or has survived the contact with water.

Hello Julien. SpeedBox itself is water resistant but the connectors might be damaged by the water. Unplugged connectors obivously can not be water resistant. This is why we recommend to use some protective spray made for such purposes.


Do you think it will be possible to tunning in the future the new motor bosch 2020 ?

Jiří Voldán (Sales Manager)Administrator |

Hello, yes of course. We're on it.

Hi, is it only the Speedbox B which works with the performance line CX/intuvia?

Jiří Voldán (Sales Manager)Administrator |
