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. 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.
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. This also means that the box cannot break anything in the engine. 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. If you have any questions, whether general or about a specific problem, feel free to contact us.
