Badass eBikes proudly presents: the new, improved badassBox 4 Brose

The badassBox 4 is the result of over a year of development. We completely redesigned the housing, made it slimmer, and replaced the O-ring from the previous version with our patented snap-lock. The slimmer design makes it even easier to attach. The new snap-lock means you can attach and remove your badassBox with one hand in seconds. By customer request, we have additionally added an optional safety feature on the snap-lock using a cable tie.

The CR2 battery has been replaced by an AAA battery, so you can find replacement batteries much cheaper at practically any store. The tool-free battery change can be done quickly and easily while you are on the go. We recommend replacing the battery at least once a year at the start of the season. Thanks to our specially patented field enhancement technology FEET (Field Enhancement & Elimination Technology), you can go very far with a single battery. To protect them against moisture and mechanical stress, the electronic components are bonded into the housing 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 every badassBox individually. Customer satisfaction and quality are our top priorities. If you have any questions, please do not hesitate to ask us; we will get back to you with an answer immediately, usually on the same business day.

In a nutshell

The badassBox attaches to the e-bike's speed sensor and overrides the 25 km/h speed limit. Remove it and your e-bike returns to its original state.
