Badass eBikes proudly presents: the brand new badassBox 4 Panasonic

The badassBox 4 is the result of more than a year's development. We have completely re-designed the casing, with patented snap-lock fastening and a unique shape. The new snap-lock fastening means you can attach and remove your badassBox with just one hand in seconds.

We use a single 1.5 V AAA battery. Replacement for the supplied battery can be purchased cheaply and literally on every street corner. Tool-free battery change can be carried out quickly and easily while you're on the road.We recommend replacing the battery at least once a year at the start of the season. Due to our specially patented field enhancement technology FEET (Field Enhancement & Elimination Technology) you get very far with one battery. 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 – e'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 1 month money-back guarantee.

In a nutshell

The badassBox is attached to the speed sensor of the e-bike and overrides the 25 km/h speed limit. Remove it and your e-bike is restored to its original state.

Installation

The badassBox 4 Panasonic is fitted over the Panasonic speed sensor next to the rear wheel. When the snap-lock clicks into position, the badassBox is fitted securely to the sensor.­

When the badassBox is first fitted, the spoke magnet that comes with it must be mounted in place of the original magnet. Without the badassBox, our spoke magnet functions identically to the original magnet, but when the badassBox is fitted, the spoke magnet is necessary for our patented field enhancement technology to work properly. 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.

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.).
