Product description

The badassBox 4 is the result of over a year of development work. We have completely redesigned the case, made it slimmer, and replaced the O-ring of the previous versions with our patented snap closure. Slimmer means there are no longer too tight fitting situations. The sensor application is only a minimum of 3 mm - less is hardly possible. With the new snap closure, you can put the badassBox on and take off in no time at all with just one hand. On customer request, we also provided an optional attachment lock by means of cable ties on the snap closure. We replaced the CR2 with one AAA battery. Replacement for the included battery is available at every corner. You can change the replacement once a year on site without tools in no time. You only have to do this once a year or after over 7000 km, because we have increased the range of the badassBox again. This was possible thanks to our own developed and patented FEET field reinforcement technology (Field Enhancement & Elimination Technology). To protect against moisture and the mechanical stress on the wheel, the electronics are glued into the housing with a special casting compound and completely sealed. We develop and manufacture the badassBox completely ourselves. Before and after casting, we check each individual BadassBox for correct function. Customer satisfaction and quality are our top priority. We are happy to answer any question โ€“ usually the same working day. Due to the high quality and our focus on customer satisfaction, we also offer a 1 month money back guarantee. Short and crisp: the badassBox is attached to the speed sensor of the e-bike and lifts the 25 km/h limit. The e-bike is set back to its original condition. Contactless e-bike tuning. Slim, taste-protected housing. Patented snap closure. Security option on the housing. AAA battery for over 7000 km range. Potting compound from the automotive industry. Double quality control. Made in Germany. Replaces badassBox 4 Shimano and badassBox 4 Shimano Freeze. Compatible and tested up to included. Firmware 4.8.0 compatible with electronic circuits (Di2) mounting. The badassBox 4 Shimano 2019 is mounted via the Shimano speed sensor next to the rear wheel. When the snap lock locks into place, the badassBox is securely attached to the sensor. Optionally, the badassBox can be additionally secured by means of a cable tie. For initial installation, the supplied spoke magnet must be mounted instead of the original magnet. Our spoke magnet works without badassBox identical to the original magnet, but is necessary for the function with our patented field reinforcement. 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 closure. And you're done! After removing the badassBox, the spoke magnet must be reset to the original position. How it works: the badassBox transmits a modified signal without contacting, without electrical connection to the motor, without interference with the motor electronics or software to exceed the speed limit. It is not necessary to open the engine elaborately. There is no risk of damage. The badassBox can be put on and taken off in seconds and the e-bike is thus returned to its previous, legal state. With all the advantages, incorrect speed, as well as derived values are displayed. We recommend the use of GPS related additional devices (mobile phone, bicycle computer, etc.). Technical data: dimensions 61 x 40 x 15 mm, weight badassBox 27 g with battery 37 g, battery 1.5 V AAA battery (IEC R03)

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days โ€” so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
