The SpeedBox 1.3 B.Tuning is a real feat for cyclists who demand the very best from their Bafang VAE. It unlocks the speed of your electric assist, allowing you to explore new horizons on private land or where legislation permits. Installation is surprisingly simple and discreet, preserving the original look of your bike while boosting its capabilities. It’s the perfect choice for intelligent, reliable optimisation, offering a riding experience that’s both powerful and customisable.
Compatibility
- Designed specifically for VAEs fitted with Bafang Max Drive M300, M400 and M420 motors, compatible with UART and CAN protocols.
- Compatible with the SpeedBox application.
Features
- Speed limiter: This module doubles the speed limit for electric assistance, from 25 km/h to 50 km/h.
- Bluetooth connectivity and mobile application: connect your VAE to your smartphone via Bluetooth. The SpeedBox application lets you control the tuning, set your own assistance speed limit, record and view your journeys, activate an “invisible mode”, lock the engine and access engine diagnostics.
- Data display: Your EAB’s display shows actual speed up to 23 km/h; above that, full data is available via the SpeedBox app. Your EAB display also shows the parameters of your journey.
- Activation/Deactivation: Tuning can be activated or deactivated via the mobile app or by pressing the LIGHT button on your EAB. An active light icon will appear briefly on activation, indicating that you can drive at 50 km/h.
Installation and maintenance
- Installation is disconcertingly simple, thanks to coloured connectors that cannot be misplaced.
- Detailed instructions and videos are provided to guide you step by step.
- The module is easy to disassemble if necessary.
- Crucial tip: We recommend that you ride a new bike for at least 1 km before activating the tuning function.
How it works
SpeedBox 1.3 B.Tuning ingeniously interposes itself into the system of your EAB to modify the speed sensor signal before it reaches the motor. This makes it possible to bypass the default speed limit, by making the bike’s system believe that you are travelling at a lower speed than in reality (for example, 25 km/h instead of 50 km/h). In this way, the electric assistance remains active beyond its usual limit. Thanks to Bluetooth connectivity and the SpeedBox application, you have precise control over the settings (including the customisable speed limit) and real-time access to your performance data. This system guarantees smooth, continuous assistance for a powerful, tailor-made ride.
Assembly
Assembly of the SpeedBox 1.3 B.Tuning has been designed to be accessible to everyone, without the need for complicated tools or advanced technical knowledge. The kit is designed to connect directly to the original connectors on your EAB, making installation almost foolproof. It usually 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.
