The performance of the motor remains untouched. But the speed limit is gone. Your legs and physics are the limit.
Slide the badassBox onto the speed sensor, move the spoke magnet. Tuned in no time - and back to original condition just as quickly.
There is no electrical contact with the motor, battery or display - everything remains as it is.
We know our business. We are reachable. We never leave our customers out in the cold.
We are developing and manufacturing the badassBox in Germany since 2013.
Your new badassBox 5 is compatible with every adapter we offer to support multiple drive systems. Now and in the future.
We developed a dedicated App for your smartphone in which you are able to adjust tuning settings, see your actual speed and much more! Available for iOS and Android.
The badassBox 5 was designed from the ground up to match the new modular philosophy we developed. It is now smaller and equipped with a water and dust resistant seal.
It is now possible for you to update the firmware of the badassBox 5 yourself. Thanks to its Bluetooth functionality it is always up-to-date and we are able to ship new features directly to you.
The badassBox may not be operated in road traffic or within the scope of the German StVO. Use is only permitted on private property. Before using the badassBox, check whether and how its use is permitted in your area.
Fitting the badassBox may invalidate the bike's warranty. Use of the badassBox is at your own risk and peril.
We, the manufacturer, accept no liability for damage to objects and/or persons caused by improper use of the badassBox and/or accessories.
Despite all the claims by manufacturers and workshops, firmware updates and upgrades for e-bikes are also gateways to features that could take away or restrict your choice of tuning.
We therefore recommend that you do not carry out any updates or upgrades to the motor firmware or have them carried out, for example by a bike service center, in order to retain the option of tuning.
An e-bike that works probably does not need an update.
