The BadassBox 4 Bafang is fitted over the speed sensor next to the rear wheel. When the snap-lock clicks into position, the BadassBox is fitted securely to the sensor. For extra secure fitting, the BadassBox can also be fastened with a zip tie.
Once the badassBox has been fitted onto the sensor, the spoke magnet must be offset to the casing edge in the direction of the snap-lock clasp. It's now ready for use.
Following removal of the BadassBox, the spoke magnet must be returned to its original position.
How it works
The contactless and wireless badassBox transmits a modified signal in order to override the speed limit of your e-bike – without interfering with the motor's electronic circuitry or software. There's no need to open the motor and there is no risk of damaging it. The badassBox can be fitted in seconds – and just as quickly removed, restoring your e-bike to its former road-legal condition.
For all these advantages, a wrong speed, and values derived from it, are displayed. We recommend the use of GPS-related accessories for a more precise data acquisition of driving data (smartphone, bike computer, etc.).
