New generation tuning chip with Bluetooth technology and smart app for your pedelec. Our most powerful and versatile product.

The new SpeedBox B.Tuning offers a unique connection between an e-bike and a smartphone. The chip has been optimized down to the smallest detail for performance and maximum driving pleasure. The chip deactivates the speed limit of the pedelec and you can drive as fast as you like. With the SpeedBox app you can monitor and record all driving parameters on the display of your smartphone. Always and everywhere.

How does SpeedBox 3.0 B.Tuning work?

Our latest chip is also easy to use. You can activate the SpeedBox 3.0 B.Tuning chip in a SpeedBoxApp or on an e-bike display. After briefly activating the WALK function, the display briefly shows 9.9 km/h (6.2 mph) after a few seconds and from then on you can drive at unlimited speed.

To disable the chip function, enable the WALK function again to cancel the chip function. The display shows 2.5 km/h and the speed limit of 25 km/h is switched on again. The pedelec then works as it did before the chip was installed.

We thought of e-bikes that don't have a classic control panel with WALK function. In this case, simply use the key combination + - + -. Then the SpeedBox is activated. You can also simply deactivate the SpeedBox.

When you start the SpeedBox app for the first time, you will be asked to set a PIN. You then use this PIN every time you start the SpeedBox app. After selecting the PIN, you will also be prompted to set a service password to use in case you forget or want to change the PIN.

To set the maximum speed, you can in a SpeedBox app or by switching the mode three levels down and then three levels up: Turbo - EMTB - Tour - Eco - Tour - EMTB - Turbo. The current speed limit is then displayed. To change the maximum speed, briefly press the WALK button or rotate the rear wheel 360°. The indicated speed of 1.5 km/h corresponds to a maximum speed of 15 km/h, 2.0 corresponds to a maximum speed of 20 km/h, 2.5 corresponds to a maximum speed of 25 km/h, 3.0 corresponds to a maximum speed of 30 km/h, 9.9 corresponds to a maximum speed of 99 km/h. The last displayed limit is saved after five seconds of inactivity.

When using the SpeedBox 3.0 in 4th generation Bosch motors (from year of manufacture 2020), the e-bike must remain switched on after the end of the ride until the display shows a constant speed of 0.0 km / h. During this phase, the display shows the remaining time (in minutes). Then you can park the bike safely and look forward to the next ride.

SpeedBox App for SpeedBox 3.0 B.Tuning

The SpeedBox app specially developed for SpeedBox 3.0 B.Tuning uses Bluetooth technology to connect your e-bike to your smartphone. After downloading the app and pairing the smartphone with the e-bike, you can see the current data and riding parameters on the smartphone display. You can save individual trips, compare with friends and track your own performance. So you can enjoy the ride to the fullest and leave the parameter check for later.

SpeedBox B.Tuning is not required to use the SpeedBox App. However, it's a great accessory that gives you a complete view of your performance.

Download the SpeedBox app to your smartphone before ordering the SpeedBox 3.0 B.Tuning chip. Try the demo version, get to know all the functions and at the same time make sure that the APP is fully functional on your smartphone. To connect to the SpeedBox B.Tuning chip, your phone must have Bluetooth 4.0 or higher.


To connect the SpeedBox chip to an e-bike we use colored connectors equipped with a key for correct connection, so installing the chip is really easy. We have written detailed instructions and made videos that any customer can use to install the SpeedBox. Removing the tuning chip is as easy as installing it. If you have some connection problems, please don't hesitate to contact us.
