BadassBox 4 for Giant eBikes with Integrated Speed Sensor

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. 

IMPORTANT: This version is only compatible with Giant eBikes equipped with the integrated speed sensor on the chain stay (see below)


  • Contactless e-bike tuning
  • Streamlined, registered design for casing
  • Fastening by cable ties
  • Patented field enhancement technology
  • Auto industry potting compound
  • Doubled quality control
  • AAA battery for range in excess of 7,000km
  • Made in Germany
  • 30 day returns/exchange


    The BadassBox 4 Giant is fitted over the chain stay 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 aligned to the BadassBox. It's now ready for use.
