Using the kit

The Badassbox Unclamping Kit collects your real speed thanks to the magnet on your bike. Then it transmits remotely, a signal to the Bosch motor of your bike. No electrical connection is necessary. The kit does not interfere with the electronic components of your engine as 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.

Detailed operation

The Bosch 4 Badassbox 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 beyond this speed. If you remove the Badassbox 4 kit, your bike will return to its original state.

The badassbox 4 is the latest version of the Badass kit for Bosch motor. The new, thinner housing is equipped with a snap closure which facilitates assembly and disassembly of the kit on your electric bike. The case is also very resistant since it closes via a clip system used by the automotive sector. The design of the badassbox 4 has been redesigned. The kit is powered by a AAA battery which gives him a long autonomy. The 4 Bosch badassbox is designed in Germany, "Deutch quality"!

Assembly tutorial

The 4 badassbox attaches to the speed sensor located at the rear wheel of your electric bike. Thanks to the snap closure, you will not risk getting the kit off the hook. Securely attached to the frame, you can use the supplied cable tie if you wish.

  1. For the kit to be operational, it is necessary to move the magnet placed on the radius of the rear wheel, towards the edge of the box (in the direction of closing of the kit).
  2. If your magnet touches the badassbox, then place the magnet as close as possible to the badassbox and turn it to 90 °.
  3. If you need to remove the badassbox from your electric bike, be sure to replace the magnet in its original position.

The innovations of the Bosch 4 badassbox

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 4 badassbox very quickly to 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 its proper functioning. This guarantees you to have a functional finished product. And because the zero risk does not exist, the badassbox benefits from a 3 month warranty.
