Tuning Chip Set E-Bike SPEEDBOX 3.0 B.TUNING `20/`21 (Gen4) with crank puller

With the SpeedBox B.Tuning 3.0 tuning module, the latest generation of many Bosch drives can be manipulated, because the chip removes the speed limit of 25 km/h and it is installed invisibly directly on the motor. It is compatible with Bosch Active Line, Active Line Plus, Performance Line and Performance Line CX, incl. 4th generation motors. In combination with the app, a completely new riding experience is guaranteed.

This SpeedBox B.Tuning 3.0 tuning module connects the e-bike with the smartphone. Not only can the module be controlled via the free app, but all technical data can also be read out. The display shows real values and the motor can be locked via the software, keeping thieves away. The Czech manufacturer SpeedBox has hit the jackpot with this module.

• Display of real values
• Control via display and APP via Bluetooth
• All technical data visible on the smartphone
• Engine lock prevents unauthorised use

Starting with the SpeedBox B.Tuning 3.0

Note: Of course, the tuning module can also be used without the app. However, you will then forego the many additional functions provided by the software.

The tuning module can therefore be activated via the app or the display. If the WALK button is pressed, the display briefly shows "9.9 km/h". Now speeds of up to 99 km/h are available. If the WALK button is pressed again, the display returns to "2.5 km/h", i.e. the speed limit of 25 km/h is activated. If the e-bike does not have a WALK button, the button combination "+-+-" is used. The speed box is then also activated and is also switched off again in this way.

In addition, a PIN and a service password are set up when using the app for the first time.

Setting the maximum speed

Select a mode: Turbo - EMTB - Tour - Eco - Tour - EMTB - Turbo. The current speed limit is displayed in each case. To change, briefly press the WALK button or turn the rear wheel 360 degrees. The display of "1.5 km/h" corresponds to a maximum speed of 15 km/h, "2.5 km/h" stands for 25 km/h and so on. The last limit displayed is saved after five seconds.

If you are riding with 4th generation Bosch motors (from 2020), the e-bike must remain switched on after the ride until the display shows "0.0 km/h".

IMPORTANT: If you are riding with Bosch 4th generation motors (from 2020), the e-bike must remain switched on after the ride. After a few minutes, a countdown from 10 to 0 starts and then the display and tuning chip switch off automatically. This countdown must be waited for in order to prevent a "504" error message. There is also a video below in which this is explained in detail: https://youtu.be/gkUWGJw_5rI

The app

After you have downloaded and installed the app, it can be connected to the e-bike. You will then see the current data and settings on your smartphone. Take your time and check out the many different functions of the app.

Assembly and disassembly

The colour-coded plug connections make assembly relatively easy. After you have gained access to the engine, simply disconnect the existing connections and insert the tuning module in between. It is just as easy to remove the module and restore it to its original condition. We have linked several videos below this product description that explain the installation very clearly.

Note: If the tuning module is installed on a brand new e-bike, you should have ridden the bike for at least one kilometre beforehand.

It is recommended not to update the software of the e-bike. This may affect the function of the Speedbox.

Conclusion: In combination with the app, SpeedBox B.Tuning 3.0 becomes one of the most powerful modules on the market.
