BadassBox 4 Shimano eBikes
The badassBox is attached to the speed sensor of the e-bike and overrides the 25km/h speed limit. Remove it and your e-bike is restored to its original state. Please note, this device will result in the wrong speed being displayed.

The badassBox 4 Shimano 2019 is fitted over the Shimano 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 cable binder.
When the badassBox is first fitted, the spoke magnet that comes with it must be mounted in place of the original magnet. Without the badassBox, our spoke magnet functions identically to the original magnet, but when the badassBox is fitted, the spoke magnet is necessary for our patented field enhancement technology to work properly. 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.).
