Where is your sensor?
The speed sensor and its positioning are decisive for which badass box you need.
We distinguish between the classic mounting on the chain stay and the integrated mounting in the area of the dropout.
Brose Sensor
If this sensor of your Brose motor - as shown in the picture below - is located on the chain stay of your bike, then the badassBox4 Brose is exactly what you need.

Badass eBikes proudly presents: the new improved badassBox 4 Brose
The badassBox 4 is the result of more than a year's development. We have completely re-designed the casing, made it more streamline and replaced the o-ring of the previous version with our patented snap-lock fastening. Making it more streamline makes it even easier to fit. The new snap-lock fastening means you can attach and remove your badassBox with just one hand in seconds. At customer's request, we have additionally added an optional securing feature on the snap lock using a cable tie.
The CR2 battery has been replaced with a AAA battery, so you can pick up replacement batteries much cheaper on just about any street corner. Tool-free battery change can be carried out quickly and easily while you're on the road. We recommend replacing the battery at least once a year at the start of the season. Due to our specially patented field enhancement technology FEET (Field Enhancement & Elimination Technology) you get very far with one battery. To protect against moisture and mechanical stress, the electronics are glued into the casing and completely sealed with a special casting compound.
The badassBox is developed and manufactured exclusively by us in-house. Before and after casting we check each badassBox individually. Customer satisfaction and quality are our top priorities. If you have any questions, don't hesitate to ask – we'll get back to you with an answer straightaway, mostly on the same working day. Due to the high quality and our focus on customer satisfaction, we additionally offer a 1 month money-back guarantee.

Installation
The badassBox 4 Brose is fitted over the Brose speed sensor next to the rear wheel. When the snap-lock clicks into position, the badassBox is fitted securely to the sensor. For extra secure fitting, the badassBox can also be fastened with a zip tie.
Once the badassBox has been fitted onto the sensor, the spoke magnet must be offset to the casing edge in the direction of the snap-lock clasp. It's now ready for use.
Following removal of the badassBox, the spoke magnet must be returned to its original position.

How it works
The contactless and wireless badassBox transmits a modified signal in order to override the speed limit of your e-bike – without interfering with the motor's electronic circuitry or software. There's no need to open the motor and there is no risk of damaging it. The badassBox can be fitted in seconds – and just as quickly removed, restoring your e-bike to its former road-legal condition.
For all these advantages, a wrong speed, and values derived from it, are displayed. We recommend the use of GPS-related accessories for a more precise data acquisition of driving data (smartphone, bike computer, etc.).

Spoke Magnet with Thumb Screw
With the badassBox 4 Brose CS set you not only get all the necessary parts to tune your e-bike in one 'click', but you also save money.
Installation
The pin-shaped CS sensor is located in the area of the dropout.
To get to the sensor you have to remove the rear wheel.
Unscrew the screws of the bracket that secures the sensor to the dropout.
Separate the sensor from the bracket.
Insert the pin-shaped sensor into the adapter so that the flat side of the sensor is aligned with the corresponding
recess in the adapter.
The sensor must be inserted completely into the adapter,
so that only the cable protrudes and the
snap closes flush with the surface of the adapter.
(In the photo, the sensor is not yet completely inserted).
Attach the adapter to the frame of your bike with the supplied cable ties.
Reinstall the rear wheel.
Slide the badassBox onto the adapter until it clicks into place.
Mount the spoke magnet and align it with the edge of the badassBox housing.
That's it. Have fun with your faster e-bike!
