Badass eBikes proudly presents: the new and improved badassBox 4 for Bosch

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

The CR2 battery has been replaced by an AAA battery, so you can get replacement batteries much cheaper at practically any corner. 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 Elimination and Enhancement Technology), you can go very far on a single battery. To protect them against moisture and mechanical stress, the electronic components are bonded to the housing and fully sealed with a special potting compound.

The badassBox is developed and manufactured exclusively by us in-house. Before and after casting, we check every single 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 is attached to the e-bike's speed sensor and overrides the 25 km/h speed limit. Remove it and your e-bike will return to its original state.
