Badass Box 4 for Bosch E Bikes
The latest and so far best Badass Box especially for electric bikes with Bosch mid-mounted engines. This tuning tool completely removes the 25 km/h speed limitation which allows you to get the full power out of your Bosch drive system. Of course, the tuning can be cancelled at any time and the E Bike can be restored to its original condition without problems.
After installation, the Badass Box 4 transmits a modified signal to the engine so that the 25 km/h speed limit is completely lifted. That means you can achieve (theoretically) unlimited speed values. This is done without direct contact and without electrical connection to the motor, so damage to the drive system is absolutely impossible.
Important note: When the tuning is activated (=Box attached), the E Bike display will no longer show the correct speed (this also applies to derived values). To measure the real speed, we recommend using GPS-based devices, which are usually more accurate anyway (smartphones, bicycle computers, etc.).
The best Badass Box ever
One of the most important new features of the Badass Box V4 for Bosch is a new, slimmer housing with patented snap lock, which makes it much easier to attach and remove the box (the snap lock replaces the O-ring of the previous version). Thanks to the slimmer design, an installation situation that is too narrow is no longer possible. Now the Badass Box can easily be attached or removed with only one hand, so that you can switch the tuning on or off at any time. In addition, the range has been significantly increased (7,000 km) and the box is now even more robust thanks to special casting compound from the automotive industry. By the way, following customer requests, an optional securing device by means of cable ties on the snap lock was provided.
The previous CR2 battery was replaced by a new AAA battery, which only needs to be replaced every 7,000 km or after 1 year (due to battery discharge). The high range is made possible by an especially developed field enhancement technology called FEET ("Field Enhancement & Elimination Technology"). Of course, the battery can be changed at any time - corresponding AAA batteries can be bought practically everywhere at a reasonable price. You can easily exchange the battery yourself, you don´t even need tools.
Thanks to the special casting compound, the Badass Box 4 is now optimally protected against moisture and mechanical stress.
Every Badass Box 4 is double-checked for correct function during the production process.
This tuning tool is a quality product made in Germany.

Badass Box 4 for Bosch – Installation
The installation of the Badass Box 4 is simple and can easily be done by technical laymen at home - the engine does not have to be opened. The box simply has to be fitted over the Bosch speed sensor next to the rear wheel. As soon as the snap lock engages, the box is securely fastened. An additional (optional) securing via cable ties is possible, too.
We recommend replacing the spoke magnet screw with the supplied Toolfree screw during initial assembly. This makes future relocation of the screw possible without any tools whatsoever. This is important for the following reason: After the Badass Box has been placed on the sensor, the spoke magnet must be moved to the edge of the housing in the direction of the snap lock. If the spoke magnet touches the Badass Box, the spoke magnet must be placed as close as possible to the Badass Box and turned by 90° - that´s all, the installation is finished and the tuning activated!
To cancel the tuning, simply pull off the box and move the spoke magnet back to its original position - thanks to the Toolfree screw, this can be done within seconds, without any tools.
