BadassBox 4 for Giant 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. 

Please note: This is only compatible with Giant eBikes with the pin shaped speed sensor shown below



  • Patented snap-lock fastening
  • Securing feature on the housing
  • AAA battery for range in excess of 7,000km
  • Made in Germany
  • 30 day returns/exchange


    The BadassBox 4 Giant 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.
