Pendix is a German company that launched their first engine in mid 2015. The Pendix eDrive system is a retrofit kit that can be used to upgrade conventional bicycles to real motorized e-bikes. The Pendix system has the advantage to be compatible with almost all bicycle frame types and circuit types. It can therefore be used with almost all bicycle models. There are now several versions of the Pendix eDrive kit such as the eDrive 150 (32Nm), eDrive 300 (50Nm), eDrive 500 y el eDrive 100 (65Nm). The latest Pendix generation is a gearless mid-engine. As for today, there is only one tuning available on the market to derestrict the Pendix engines with the old speed sensor shape. For this purpose, the Caja badass Es una caja de ajuste sin contacto que se desliza sobre el sensor de velocidad y se instala y desinstala con solo unos clics. Solo es compatible si el imán está ubicado en el radio de la rueda.
