SpeedBox is a revolutionary upgrade for your e-bike with a Shimano motor. With its new design, modern hardware, and firmware, it breathes new life into your e-bike.
(Note! This model includes Bluetooth)
This SpeedBox 3.0 is designed to fit perfectly with e-bikes equipped with Bosch motors including Gen4 (non smart only):
- Active Line (Plus), Cargo Line, Performance Line (Speed, CX)
Note! This model does not work if you have the so-called Smart System with rim magnet. These models require SpeedBox 1.1 or 1.2.

SpeedBox is very easy to use, especially this model, which includes Bluetooth and its own app that we highly recommend!
The tuning kit can be activated directly from the mobile application or from your e-bike's display. Activate SpeedBox 3.0 by briefly activating the walk assist function. A value of 9.9 km/h (6.2 mph) will display, allowing you to ride at speeds of 40 km/h, 50 km/h, or even over 60 km/h.
To deactivate the tuning chip, briefly activate the walk assist function again. The value 2.5 km/h (1.6 mph) will appear on your display, resetting the speed limit to 25 km/h. Your e-bike will function as it did before the chip was installed.
SpeedBox is also designed for e-bikes without a classic control unit with walk assist. In this case, use the combination of - + - + buttons to activate SpeedBox. You can deactivate SpeedBox in the same way.
You can set the maximum speed for electric assistance by switching modes: Turbo - EMTB - Tour - Eco - Tour - EMTB - Turbo. A current speed limit will display afterward. The maximum speed for electric assistance can be changed by briefly pressing the walk assist function or rotating the rear wheel 360°. A value of 1.5 km/h on the display corresponds to a limit of 15 km/h, 2 km/h to 20 km/h, 2.5 to 25 km/h, 3.0 to 30 km/h, 9.9 to 99 km/h, etc. The last shown limit is saved after 5 seconds of inactivity.
The SpeedBox App is specifically designed for SpeedBox 3.0 B.Tuning, which uses Bluetooth technology to connect your e-bike to your mobile phone. After downloading the app and connecting your phone to your e-bike, you can view current data and trip parameters on your phone. Save your rides, compare results with friends, and monitor your performance and progress. This allows you to fully enjoy the ride while leaving performance data analysis for later.
Features of the SpeedBox App:
SpeedBox 3.0 B.Tuning is not limited to the SpeedBox app, but it's a great tool that provides a complete overview of your performance. We recommend downloading the SpeedBox app to your phone before ordering the SpeedBox 3.0 B.Tuning chip. You can try our demo version to explore all the amazing features and ensure the app is fully functional on your phone. To connect to the SpeedBox B.Tuning chip, your phone must support Bluetooth 4.0 or higher.
Our SpeedBox uses original connectors for easy and safe installation. Check out our instructional videos and guides for a seamless experience.
When using SpeedBox 3.0 with Bosch motors from the 4th generation (manufactured in 2020 or later), it’s necessary to leave the bike on after your ride until a value of 0.0 km/h is displayed. During this process, the remaining time will be shown in minutes. Once complete, it is safe to turn off your bike, and you can look forward to your next ride.
SpeedBox uses original connectors, ensuring that the installation process is very simple and the chip connects properly. Detailed instructions and videos are available to make installation easy for you. Removing the tuning chip is just as easy. If you have any issues with installation or removal, please don’t hesitate to contact us.
If you plan to install SpeedBox on a brand-new bike, make sure to ride at least 1 km before activating the chip.
Note! Before updating the software on your e-bike, first disconnect SpeedBox from the e-bike, update the software, and then reinstall SpeedBox.

Allowing the motor in your e-bike to assist at high speeds may cause extra wear on the motor. Avoid excessive speeds. A recommended maximum speed setting is often 30-35 km/h, though it is entirely up to you.
