The motor is the centerpiece of an e-bike. The belt drive from Brose Antriebstechnik features an extremely quiet, robust and low-maintenance design and makes for a feeling of natural riding. The belt is installed in a protective housing. For reliable proof of the most recent maintenance, Schreiner ProTech developed a tamper-evident label with first-opening indication for Brose Antriebstechnik modified to suit the customer’s needs and the application.
