Badass Box 4 for TQ

Badass Box 4 for TQ

Put an end to the 25 km/h speed limit! The tried and tested Badass Box is now also available in an optimised version 4 especially for e-bikes with TQ mid-mounted motors (not compatible with Haibike Flyon). This tuning tool can be installed without much effort and removes the speed limit completely. This allows the TQ drive to develop its full power and you can ride much faster with full motor support.

A real advantage of this tuning tool is that the original legal condition of the e-bike can be restored within seconds. All you have to do is move the spoke magnet to its original position and pull off the Badass Box - thanks to a patented snap lock and a supplied lobe screw, this is now easier than ever. You don't even need any tools.

Developed and manufactured in Germany.

How it works

After attaching the Badass Box 4, it transmits a modified signal so that the preset 25 km/h speed limit can be exceeded. This is done without direct intervention in the motor electronics or software (contactless e-bike tuning).

Important note: Due to the special mode of operation of the Badass Box 4, the display of your e-bike will no longer show the correct speed when the box is plugged in (= tuning active). This also applies to values derived from it.

We therefore recommend GPS-capable additional devices such as smartphones or bike computers to display the real speed on the road.

Advantages compared to previous versions

Compared to the previous versions, the Badass Box 4 has been optimised in many ways - here are the most important innovations at a glance:

The housing of the Badass Box 4 has been completely redesigned, and the O-ring of the previous version has been replaced by a patented snap lock. This makes attaching and detaching the box easier and faster than ever before.

New battery: The CR2 battery has been replaced by a more powerful AAA battery. This only needs to be replaced about once a year or after about 7,000 km. Changing the battery is very easy and suitable replacement batteries can be found practically on every corner. The high range of up to 7,000 km is made possible by the self-developed, patented field enhancement technology FEET ("Field Enhancement & Elimination Technology").

The Badass Box 4 has a much slimmer design, so that installation situations that are too tight are completely a thing of the past.

At the customer's request, an additional, optional fastening security by means of cable ties on the snap lock is now possible.

Robust and resistant

To ensure that the electronics of the Badass Box are optimally protected against moisture and mechanical stress, they are glued into the housing using a special potting compound and completely sealed (the potting compound even originates from the automotive industry). Before and after potting, each individual box is checked to ensure that it functions correctly.

Badass Box 4 for TQ - Installation

Compared to other e-bike tuning tools, the Badass Box 4 can be easily installed and also uninstalled again. It is not necessary to open the engine.

In principle, the Badass Box only needs to be placed on the speed sensor of the e-bike. As soon as the snap lock engages, you know that the box is securely fastened. Optionally, an additional fastening with cable ties is possible.

Note on initial installation: For the very first installation, you should replace the screw of the spoke magnet with the supplied lug screw. This has the advantage that the spoke magnet can be moved in the future without any tools. After placing the Badass Box on the sensor, the spoke magnet must be moved towards the edge of the housing in the direction of the snap lock. When the magnet touches the Badass Box, it must be placed as close as possible to the box and turned 90 degrees. This completes the installation and the Badass Box is active - your e-bike is tuned and you can take off!

If you want to cancel the tuning and return the bike to its original legal condition, simply remove the Badass Box and return the spoke magnet to its original position. Thanks to the supplied lug screw, this can be done in a few seconds.
