E-bike tuning - short and sweet

Tuning your e-bike does not mean making the motor stronger. The power remains at 250 watts, but you get motor support beyond the 25 km/h limit. If the 250 W support normally stops abruptly at 25 km/h, the pedalling power required to maintain the speed is not pleasant for many and is perceived as "riding into a wall". This can be prevented by tuning. The motor support is there for longer and only when the combined motor and human power can no longer stand up to physics (air and rolling resistance, slope downforce, etc.) is further propulsion slowed down slowly and homogeneously. Typical speeds that can then be ridden in the long term are around 35 to 40 km/h with tuning. Beyond that, much more physical power is needed, usually too much for mere mortals and non-professional cyclists. For this reason, and because of the increasing efforts of engine manufacturers to prevent tuning, we have set a default speed of 40 km/h. However, you can change this value between 25 km/h and 50 km/h. 

Our badassBox is a non-invasive tuning, i.e. it does not require any intervention in the engine system, no engine has to be removed or any cable solutions installed in the frame. Instead, we just slide our box over the speed sensor and that's it. With some sensor types, the sensor also has to be mounted on the box, with integrated sensors, these have to be relocated once. But all in all, this is no big deal and can be done in a few simple steps. This makes it possible to switch quickly between legal and tuned operation. This is a great advantage, especially when the next visit to the bike dealer is imminent. The disadvantage of this method, however, is that your display "only" shows you the manipulated speed. And this is no longer done by halving the real speed as it used to be, but in a non-linear way and therefore more difficult to estimate. If you want to keep an eye on your real speed or if you want to record your tour in real distances, we recommend using an ordinary speedometer or your mobile phone.

firmware-upgrade warning!

Unfortunately, firmware updates/upgrades are at the same time also a gateway for their unwanted features, which take away the choice of tuning or limit it.

We therefore recommend our customers not to carry out any upgrades/updates of the motor firmware or have them carried out at present in order to retain the option of selecting the tuning/original state. This applies in particular in connection with workshop work on your e-bike.

please note
