Badass eBikes proudly presents: the new improved badassBox 4 Giant 2020

The badassBox 4 is the result of over a year of development work. We've completely redesigned the case, made it slimmer made - which means that there are no longer any installation situations that are too tight.

The badassBox runs on one AAA battery (included). Replacement for the supplied battery you get cheap and proverbial on every corner. You can replace it yourself anywhere without tools in no time. We recommend to replace the battery at least once a year at the start of the season. Through our specially developed and patented FEET (Field Enhancement & Elimination Technology), you will get very far with one battery. To protect from moisture and the mechanical 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 casting we check each badassBox individually. Customer satisfaction and quality are our top priorities. If you have any questions, don't hesitate to ask – we'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 mounted with the speed sensor on the chainstay of the e-bike and ensures, that the motor supports you beyond the 25 km/h limit. Remove it and your e-bike is then again in the untuned and thus legal state.

Installation

The integrated Giant sensor is located in the area of the dropout.
To get to the sensor you need to remove the rear wheel.
Find the position of the integrated sensor in the dropout of your e-Bike and loosen the screws that secure the sensor.

Place the sensor in the designated recess on the badassBox.

The badassBox Giant 2020 is mounted with the sensor by using cable ties (included) on the chainstay.

For the first assembly, the supplied spoke magnet must be mounted instead of the original magnet. Our spoke magnet works without badassBox identically to the original magnet, but with badassBox mounted, it is necessary for the function of our patented field amplification.

The spoke magnet must be aligned next to the badassBox. To check the position of the magnet on the bike when stationary, lift the rear, spin the rear wheel (not the cranks!) and let it spin. Check the speedometer or app of your bike. The indicated speed should be even and slowly decrease while the rear wheel coasts down.
If the spoke magnet touches the badassBox, the spoke magnet must be placed as close as possible to the badassBox and turned 90°. Done!

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. If the badassBox is removed and the Giant sensor is mounted on the chain stay, or the original mounting situation in the dropout and the spoke magnet is aligned with it, then the e-bike is restored to the untuned and therefore legal state.

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.).
