Badass eBikes proudly presents: the new improved badassBox 4 Bosch
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 – but should only be necessary once a year, or every 7000km. This was made possible by our in-house developed and patented field amplification technology FEET (Field Enhancement & Elimination Technology). 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 3-month money-back guarantee.

The badassBox 4 Bosch is fitted over the Bosch 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. If the spoke magnet touches the badassBox, it must be repositioned as near as possible next to the badassBox and turned through ninety degrees. 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.).

After installation of the badassBox the magnet must be offset. The video shows this easy operation. ATTENTION: First time use, please exchange the Phillips screw of the magnet against the badassBox provided toolfree screw. Then the displacement of the magnet is possible without requiring any tools.
