It simply works!

The badassBox makes your e-bike much quicker in no time at all, mounted in just moments. Back on public roads, the badassBox can be removed in seconds. Your e-bike is once again legally in compliance with the regular speed limits.

You read ‘25’ – and drive 50!

Don’t be surprised at your speedometer: When your e-bike is travelling at 50 km/h with a mounted badassBox, the speed displayed is only 25 km/h. Find out below why that is the case.

This is how the badassBox works:

The badassBox reduces the speed of the motor system by half from a speed of approx. 18km/h (depending on the circumference of the wheel). It makes no difference to the motor whether it performs at full power in the lowest or highest gear. The badassBox does not affect the maximum performance. The drive limit for Pedelecs is moved to over 50km/h.

The badassBox is powered by photo battery cells (type CR2) enabling it to perform over approx. 6000 km or one year (discharged battery) thanks to low power technology. As the signal transmission takes place without an electrical contact (contactless chip tuning) electrical damage is physically impossible. A microprocessor switches on and off automatically. The battery is replaced simply by opening the base of the housing.

Sound and reliable

The badassBox Type3.4 is the fourth generation since the successful introduction of the Type3 in 2013 - and it has been continually improved since then: The housing has been strengthened, the electronics enhanced and the firmware has been adapted to the current motors of a variety of manufacturers. The current badassBox Type3.4 is now also splash proof and less sensitive to vibrations and bumps. These are only a few of many improvements that make the badassBox very reliable.

The badassBox is a quality product - every single device is inspected many times during production. Attention: The badassBox is only guaranteed to be genuine only with the seal on the base of the housing!

Unfortunately, firmware updates/upgrades are at the same time also a gateway for their unwanted features, which take away the choice of tuning or limit it.

We therefore recommend our customers not to carry out any upgrades/updates of the motor firmware or have them carried out at present in order to retain the option of selecting the tuning/original state. This applies in particular in connection with workshop work on your e-bike.


  • The badassBox is not to be used in normal road traffic or in areas regulated by the Road Traffic Act!

  • Mounting the badassBox may lead to a loss of the bicycle warranty.
