Bosch Gen2 & Gen3

Here you will find an overview of e-bike tuning products for Bosch Active Line and Performance Line motors (Gen2, year of manufacture from 2014), Performance Line CX (Gen2, year of manufacture from 2015 and from 2017) and Bosch Active Line Plus (Gen3, year of manufacture from 2017).
