Badass Box 4 for Bafang
This is a simple but highly effective tuning solution for E-Bikes with Bafang mid-mounted engines. The Badass Box 4 removes the 25 km/h speed limit of the drive system completely, allowing you to finally use the full potential of your Bafang engine. Thus the annoying speed limit will be a thing of the past - ride much faster with full engine support!
Attaching the Badass Box 4 is very easy - in contrast to many other E-Bike tuning tools, the engine does NOT have to be opened for initial assembly.
Legal within seconds
A big advantage of this tuning tool is that you can attach or detach the Badass Box in seconds if you want to restore the (legal) original condition of your E-Bike. Thanks to a patented snap lock, this can now be done even faster than ever before.
This tuning tool works battery powered. For the new Badass Box 4, the previous CR2 battery has been replaced by a more effective AAA battery (included). If the battery is empty, you can replace it with a new battery at any time, without any tools. Suitable replacement batteries are available practically everywhere in the shops. It is likely that the battery will need to be replaced once a year.
Thanks to the specially developed FEET field enhancement technology, the battery has a very high range ("Field Enhancement & Elimination Technology").
Robust and durable
The electronics of the Badass Box 4 are glued into the housing with a special casting compound and completely sealed, ensuring optimum protection against moisture and mechanical stress (the casting compound is also used in the automotive industry). Each box is tested for correct function before and after the sealing.
The Badass Box 4 is a quality product Made in Germany.
Contactless E-Bike tuning
After the Badass Box is attached, it transmits a modified signal, so that the speed limit can be exceeded. There is no direct electrical connection to the engine, and there is no interference with the engine electronics or software. Therefore unintentional damage to the motor is impossible.
Please note: Due to the special way the Badass Box works, the E-Bike display will show a wrong speed - this also applies to values derived from it.
Tip: Use GPS-based accessories such as smartphones or bicycle computers to get the correct speed displayed.
Badass Box 4 for Bafang – Installation
Attaching the tuning tool is easy. The Badass Box 4 has a slim, design-protected housing and has to be mounted to the chainstay with cable ties. Then the speed sensor of the E-Bike must be unscrewed and placed on the box.
During the first installation, the original magnet of the E-Bike must be replaced with the supplied spoke magnet. This spoke magnet works in the same way as the original magnet, but the Badass Box spoke magnet is required so that the patented field amplification works when the Box is attached.
After the sensor has been placed on the Badass Box, 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 box, simply place the spoke magnet as close as possible to the Badass Box and turn it by 90° - that's it, the installation is finished and you can start!
