badassBox 4 Bafang
Badass eBikes proudly presents: the further improved badassBox 4 Bafang
The badassBox 4 Bafang is the result of a great deal of development work and is conceptually different from our other badassBoxes. The badassBox Bafang is mounted on the chain stay using cable ties and the e-bike's speed sensor is unscrewed and placed on the box.
We have replaced the CR2- with an AAA battery. Replacement for the included battery can be obtained cheaply and literally at every corner. You can replace it yourself once a year on site without tools in the shortest possible time. To protect the electronics from moisture and the mechanical stresses on the wheel, the electronics are bonded into the housing with a special sealing compound and completely sealed.
We develop and manufacture the badassBox completely in-house. Before and after casting we check each individual badassBox for correct function. Customer satisfaction and quality are our top priorities. We are happy to answer any question – usually on the same working day. Because of the high quality and our focus on customer satisfaction, we also offer a 1 month money-back guarantee.
In a nutshell
The badassBox Bafang is mounted on the chainstay and the e-bike's speed sensor is placed on the box, lifting the 25 km/h limit. The e-bike is restored to its original condition in just a few simple steps.
- Contactless E-Bike Tuning
- Patented snap lock
- Safety option on the housing

The badassBox Bafang is mounted on the chain stay using cable ties and the e-bike's speed sensor is unscrewed and placed on the box.
For the first installation, the supplied spoke magnet must be fitted instead of the original magnet. Our spoke magnet functions identically to the original magnet without the badassBox, but is necessary for the function with our patented field reinforcement when the badassBox is fitted. After placing the sensor on the badassBox, the spoke magnet must be moved towards the edge of the housing in the direction of the snap lock. If the spoke magnet touches the badassBox, the spoke magnet must be placed as close as possible to the badassBox and turned by 90°. Ready!
How it works
The badassBox transmits a modified signal to exceed the speed limit without contact, without electrical connection to the motor, without intervention in the motor electronics or software. It is not necessary to open the motor at great expense. There is no risk of damage. The badassBox can be put on and taken off again in seconds, thus returning the e-bike to its previous, legal status.
With all the advantages, a wrong speed and values derived from it are displayed. We recommend the use of GPS-related additional devices (mobile phone, bicycle computer, etc.) for a more accurate recording of the journey data anyway.
