Badass eBikes is proud to present: the improved badassBox 4 Bafang

The badassBox 4 Bafang is the result of a great deal of development work and is conceptually different from our other badassBoxes. The Bafang badassBox is mounted on the chainstay using cable ties, and the e-bike speed sensor is unscrewed and positioned in the box.

The badassBox is powered by an AAA battery. Replacements for the included battery can be found inexpensively and literally on every corner. You can replace it yourself on-site without tools and in the shortest possible time. We recommend replacing the battery at least once a year at the start of the season. To protect the electronics from moisture and mechanical loads from the wheel, the electronics are bonded to the housing with a special sealing compound and completely sealed.

We develop and manufacture the badassBox entirely in-house. Before and after casting, we verify that each individual badassBox functions correctly. Customer satisfaction and quality are our top priorities. We are happy to answer any questions, usually on the same business day. Due to the high quality and our focus on customer satisfaction, we also offer a 1-month money-back guarantee.

In a nutshell

The Bafang badassBox is mounted on the chainstay and the e-bike speed sensor is positioned in the box, raising the 25 km/h limit. The e-bike is restored to its original state in just a few simple steps.
