The SpeedBox 1.3 is the perfect ally for cyclists who want to exploit every watt of their Bosch motor. It opens the door to higher speeds, ideal for private terrain or where regulations allow. Designed for seamless integration, it maintains the original aesthetics of your EAB while giving it increased capacity. If you’re looking for an uncomplicated way to boost the performance of your Bosch EAB, this is the choice for you.
Compatibility
- Designed for EABs equipped with Bosch Gen4 motors and the Smart System, specifically those with a Bosch Rim Magnet and the latest version of Bosch software.
- Compatible with 4th generation engines: Performance Line CX, Performance Line CX Race and Performance Line Speed.
- Warning: Not compatible with standard magnets, ABS systems, 5th generation motors (BDU384Y) or Performance Line SX.
Features
- SpeedBox 1.3 removes the speed limit for electric assistance. Although it can be used at very high speeds, a limit of 35 km/h is recommended.
- Your EAB display will not show the actual speed, but the distance travelled will be correctly indicated after a brief countdown.
- Tuning is simply activated or deactivated using your VAE’s WALK assist function or specific button combinations.
Installation and maintenance
- Installation is simplified by using your EAB’s original connectors, making the process straightforward and reducing the risk of error.
- Detailed instructions and videos are available to guide you step by step.
- The module is easy to disassemble if necessary.
- Crucial advice: It is recommended that you ride at least 10 km with a new EAB before activating tuning. To avoid detection, it is advisable not to update the firmware of your EAB.
How it works
SpeedBox 1.3 intervenes by modifying the speed information transmitted by your EAB’s sensor to the motor. It acts as a “translator”, making your bike believe that you are travelling slower than you really are. For example, even if you’re going 40 km/h, the EAB’s internal system might “think” you’re going 20 km/h, which keeps the electric assistance active well beyond its usual limit. This process ensures continuous, smooth assistance, allowing you to take full advantage of your motor’s capabilities.
Assembly
The SpeedBox 1.3 can be fitted by anyone, without the need for complicated tools or advanced technical skills. The kit is designed to fit perfectly into 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 support you every step of the way, ensuring that installation is quick and safe. You’ll be able to explore new speeds with your EAB in no time.
