The tuning tool can be activated or deactivated at any time by plugging or unplugging the box and moving the spoke magnet. Installation and use are simple.
In contrast to the previous version, the new Badass Box 4 numerous optimizations:
- The box's housing is now significantly slimmer; there can no longer be any tight installation situations.
- The O-ring of the previous version has been replaced by a patented snap closure. Thanks to the new snap closure, the Badass Box 4 can now be attached or removed in no time with just one hand. At the customer's special request, an additional optional fastening system using cable ties on the snap closure was also included.

Badass Box 4 for Brose - How it works
Once the box is attached and the spoke magnet is moved, the box transmits a modified signal to the motor, thereby removing the speed limit. This process occurs contactlessly, i.e., without a direct electrical connection to the motor, thus eliminating any potential damage.
Important note: Due to functional limitations, your e-bike display will no longer show the correct speed when tuning is active (this also applies to values derived from it). Tip: Simply use GPS-based additional devices (smartphones, bike computers, etc.) to determine the actual speed.
Badass Box 4 for Brose – Installation & activation
Since the engine does not have to be opened for installation, the installation of the Badass Box 4 is quite simple. You have to Badass Box 4 just over the Brose Slide the speed sensor onto the rear wheel. Once the snap lock clicks into place, the box is securely attached to the sensor. Optionally, you can further secure the box with a cable tie.
We recommend replacing the original spoke magnet screw with the included lobe screw during initial installation. This has the advantage that no tools are required to reposition the magnet in the future. After installing the Badass Box To access the sensor, the spoke magnet must be moved toward the housing edge, toward the snap lock. This removes the 25 km/h speed limit, allowing you to ride much faster with full motor support.
If you are the Badass Box to cancel the tuning, you must also reset the spoke magnet to its original position. Then your Brose E-bike returns to its original riding characteristics and the speedometer shows the correct speed again.
To install an E-Bike tuning chip in your E-Bike it is sometimes special tools necessary. Please check previously whether you have to open the engine compartment to access the motor connectors. This is especially true for products from the Modules, Kit, Dongle and Sensor.
Normally (but not always) opening the engine compartment requires loosening the crank. To do this, you will need a Crank puller. Some engines also have a Spider Tool This is important for opening the lock ring on the chainring - because the chainring must be loosened here so that the motor cover can be removed to access the inside of the motor. If you want to replace the chainring (wear, change the gear ratio), you often need a Spider Tool. The necessary special tools can also be found in our shop. To remove the engine cover, you usually need a Torx or Allen key. For installing the modules, appropriate Pliers from the electronics sector.

Important information on tuning measures for e-bikes and e-scooters
We expressly point out that any modification to e-bikes and e-scooters – whether through hardware tuning (e.g. tuning chips, dongles, sensor adapters) or software tuning (e.g. apps, programs or USB tools) – can have consequences.
Tuning measures on e-bikes and e-scooters mean that they are no longer permitted for use on public roads as defined by the StVZO (Road Traffic Licensing Regulations). Legal use is therefore only possible on private property or - if permitted - in competitions. Riding an e-bike or e-scooter modified by tuning measures on public roads can lead to criminal liability for driving without a license (Section 21 of the Road Traffic Act) and driving without insurance (Section 6 of the PflVG). Tuning measures on e-bikes can lead to the loss of warranty rights and manufacturer guarantees. Furthermore, tuning measures can lead to the loss of insurance coverage and benefits from accident victim assistance in the event of an accident. The e-bike (or e-scooter) modified by tuning measures is subject to additional stress due to the higher speed, which can lead to safety risks.
