Badass eBikes proudly presents: the new improved badassBox 4 Impulse

The badassBox 4 is the result of over a year of development work. We have completely redesigned the housing, made it thinner, and replaced the O-ring of the previous versions with our patented snap lock. Thinner means that there are no longer any installation situations that are too tight. The sensor application is only a minimal 3 mm - less is hardly possible. With the new snap lock, you can mount and dismount the badassBox with just one hand in no time at all. At the customer's request, we have also provided an optional fastening security device using cable ties on the snap closure.

We have replaced the CR2 battery with an AAA battery. Replacement for the supplied battery you get cheap and proverbial on every corner. You can do the exchange yourself on site without tools in no time. We recommend replacing the battery at least once a year at the start of the season. Through our specially developed and patented field enhancement technology FEET (Field Enhancement & Elimination Technology) you come with a battery very far. To protect against moisture and the mechanical stresses on the wheel, the electronics are glued into the housing with a special potting compound and completely sealed.

We develop and manufacture the badassBox completely ourselves. Before and after potting, we test every single badassBox for correct function. Customer satisfaction and quality are our top priorities. We are happy to answer any question - usually on the same working day. Because of the high quality and our focus on customer satisfaction, we also offer a 1 month money back guarantee.

Installation

You will find the speed sensor on the chainstay of your bike (as pictured). The badassBox 4 Impulse is mounted using the Impulse speed sensor next to the rear wheel. When the snap lock engages, the badassBox is securely attached to the sensor. Optionally, the badassBox can be additionally secured by means of a cable tie.

For initial installation, it is recommended to replace the screw of the spoke magnet with the supplied lobe screw for tool-free relocation. After placing the badassBox on the sensor, the spoke magnet must be moved to the edge of the housing in the direction of the snap lock. Done!

After removing the badassBox, the spoke magnet must be reset to the original position.

How it works

The badassBox transmits a modified signal contact-free, without electrical connection to the engine, without intervention in the engine electronics or software, in order to exceed the speed limit. It is not necessary to open the engine elaborately. There is no risk of damage. The badassBox is on and off in seconds, returning the e-bike to its previous, legal state.

With all the advantages, a wrong speed, as well as values derived from it, are displayed on principle. We recommend the use of GPS-related additional devices (cell phone, bike computer, etc.) for a more accurate driving data collection anyway.
