This little technological gem is designed for cyclists who make no compromises. It unleashes the speed of your Bosch SX VAE, allowing you to ride further and faster, whether on your favourite private terrain or in areas where legislation permits. Installation is surprisingly simple and discreet, preserving the original aesthetics of your bike while boosting its capabilities tenfold. The SpeedBox 1.5 B.Tuning is clearly the perfect choice for those who want intelligent and reliable performance optimisation, guaranteed for life.
Compatibility
- Designed specifically for 4th generation Bosch Performance Line SX engines (models BDU3144, BDU3145).
- Compatible with EABs equipped with a magnet on the valve (Bosch Rim Magnet) and the latest version of Bosch software.
- Warning: Not compatible with standard magnets or ABS systems.
Features
- Speed override: This module removes the speed limit from the electric assist. You can adjust this limit up to 99 km/h, although a maximum speed of 35 km/h is recommended to minimise error codes.
- Bluetooth connectivity and mobile application: connect your VAE to your smartphone via Bluetooth. The SpeedBox application lets you control the tuning, set the speed limit, record and compare your journeys, and access engine diagnostics.
- Data display: The SpeedBox app displays actual speed and other driving data in real time directly on your phone.
- Advanced modes: Take advantage of an ‘invisible mode’ for total discretion, as well as detailed engine diagnostics.
- Activation/Deactivation: Tuning can be activated or deactivated via the mobile application or the WALK assist function on the control unit of your EAB. Your VAE’s display will show 3.5 km/h (activated) or 2.5 km/h (deactivated) to indicate its status.
Installation and maintenance
- Installation is disconcertingly simple, using your EAB’s original connectors, which makes the process straightforward and reduces the risk of error.
- Detailed instructions and videos are provided to guide you step by step.
- We recommend that you ride a new bike for at least 10 km before activating the tuning.
- Crucial tip: Only activate/deactivate tuning when stationary, before starting or after completing your journey. After each ride, leave the EAB switched on until the display shows 0.0 km/h. It is also recommended not to update the firmware of your VAE to avoid the detection of the tuning.
How it works
The SpeedBox 1.5 B.Tuning ingeniously intervenes to modify the signal from your EAB’s speed sensor before it reaches the engine. This allows you to bypass the default speed limit, by making the bike’s system think you’re travelling at a lower speed than you actually are (for example, 25 km/h instead of 50 km/h). Bluetooth connectivity with the SpeedBox app gives you total control over these settings, allowing you to personalise your experience and access real-time data. This electronic manipulation ensures smooth, continuous assistance, giving you the best possible ride.
Assembly
Assembly of the SpeedBox 1.5 B.Tuning is designed to be accessible to everyone, without the need for complex tools or in-depth technical knowledge. The kit is designed to connect directly to your EAB’s original connectors, making installation almost foolproof. In general, it only takes a few minutes to connect the module between the speed sensor and the motor. Comprehensive guides and video tutorials are available to help you every step of the way, ensuring that installation is quick and safe.
