Using the kit

The unlock kit Badassbox collects your real speed thanks to the magnet on your bike. Then it transmits from a distance, a signal to the Bosch motor of your bicycle. No electrical connection is necessary. The kit does not interfere with the electronic components of your engine since it is not directly connected to the engine. So there is no risk that you damage your engine. Its installation is very simple and does not require any special tools.

If you use the Badassbox 4, the data displayed on your dashboard will be false. Starting from 18 km / h, your data will be divided by 2 automatically. As a result, your average speed, distance traveled, etc. will no longer be correct either. To compensate for this you can always use a GPS.

La badassbox 4 Bosch attaches to the speed sensor of the electric bike. Once installed your bike is no longer bridled at 25 km / h. Your Bosch engine will continue to assist you above this speed. If you remove the kit Badassbox 4, your bike returns to its original state.

La badassbox 4 is the latest version of the Badass kit for Bosch motors. The all-new thinner housing is equipped with a snap closure which facilitates assembly and disassembly of the kit on your electric bike.

The innovations of the badassbox 4 Bosch

It took 1 an R & D to design this new model of debridement kit. Compared to the previous 3.4 model, this one is thinner. With the previous version an adapter was sometimes necessary depending on your bike, with this new version it is no longer necessary. Also, the O-ring (circle-shaped) has been replaced by a patented snap closure system (or spring). So you can attach or detach the badassbox 4 very quickly with one hand. In addition, you can secure the closure using a cable tie provided with the kit.

The AAA battery now replaces the CR2 battery. It is therefore very easy to change the battery since this model is widely sold in many stores. The battery change is done quickly done well without any tools. The battery life of an AAA battery is about 1 an or 7000 km traveled. To increase the autonomy of the Badass unbridging kit FEET patent (Field Enhancement & Elimination Technology). The badass box 4 is well hermetic because the electronic components are glued in the case with a special sealing sealant and completely vitrified intractable with the slightest drop of water.

Each Badassbox is screened to verify that it is working properly. This guarantees you to have a functional finished product. And because zero risk does not exist, the badassbox enjoys a 3 month warranty.

According to article L317-5 of the Highway Code of December 24, 2019, the sale of objects making it possible to exceed the regulatory limits set with regard to the speed of a moped, a motorcycle, a personal transport vehicle motorized, motorized quadricycle or assisted pedaling cycle (electrically assisted bicycle / ebike) is prohibited in France.

We are therefore forced to no longer send to France and the French overseas territories. We thank you for your understanding,
