BadassBox

Contactless e-bike tuning directly from the manufacturer

If 25 km/h is not fast enough for you

Our popular and tried-and-tested tuning solution to remove the 25 km/h limit for e-bikes with motors from

Bafang, Bosch, Brose, Fazua, Giant, Impulse, Panasonic, Pendix, Polini, Shimano, Specialized, TQ, Yamaha

The performance of the motor remains untouched. But the speed limit is gone. Your legs and physics are the limit.

Slide the badassBox onto the speed sensor, move the spoke magnet. Tuned in no time - and back to original condition just as quickly.

There is no electrical contact with the motor, battery or display - everything remains as it is.

We know our business. We are reachable. We never leave our customers out in the cold.

We are developing and manufacturing the badassBox in Germany since 2013.
