The SpeedBox 3.1 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 with a 4-pin connector.
- Compatible with the SpeedBox application.
- Warning: Not compatible with screens using UART connectors and the Bafang Max Drive M500 motor.
Features
- Unlimited unbridling: This module removes the speed limit on electric assistance, giving you unlimited maximum speed.
- Bluetooth connectivity and mobile application: Connect your VAE to your smartphone (Bluetooth 4.0 or higher) via the SpeedBox application. This 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.
- Real-time data display: Your EAB’s display shows precise, real-time data such as maximum and average speed, daily mileage and remaining range. The mobile application also displays the actual values.
- Setting the speed limit: You can set your own speed limit.
- Activation/Deactivation: Tuning can be activated or deactivated via the mobile application, the LIGHT button on your EAB, or the + – + – button combination. When tuning is activated, the display will show 99 km/h (62 mph); to deactivate it, use the LIGHT button or the + – + – combination again, and the speed limit will return to 25 km/h.
Installation and maintenance
- Installation is disconcertingly simple, thanks to coloured connectors (4 pins) that cannot be misplaced.
- Detailed instructions and videos are provided to guide you step by step.
- The module is easy to disassemble if necessary.
How it works
SpeedBox 3.1 B.Tuning ingeniously interposes itself into the system of your EAB to modify the speed sensor signal before it reaches the motor. 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. 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 3.1 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.
