Bosch Motor Compatibility Overview
Our EBT Unlock Key is compatible with Bosch e-bike motors of all four generations. Find out below which tuning version suits your motor and get full access to the product collections for each generation.
Bosch Gen1 – Classic Line
The first generation Bosch Classic Line motors were used between 2011 and 2014 and are easily recognized by their bulky design and the large sprocket in the front.

Gen4 is not always compatible: BES2 vs. BES3 explained
Not all Bosch Gen4 motors are supported by the EBT Unlock Key. The key difference lies in the system type: BES2 (round charging port) or BES3 Smart System (square charging port). Only Gen4 motors with the BES2 system are currently compatible with browser-based software tuning.
On our dedicated comparison page, we show you exactly how to identify the correct system type — with clear photos, connector details, and practical tips.
