The US manufacturer Specialized uses motors from the German manufacturer Brose for its e-bike drive systems. However, Specialized provides the Brose motors with its own software in order to match e-bike and drive as perfectly as possible. In fact, many riders of Specialized e-bikes report a very harmonious support behaviour and a natural riding experience. Another special feature of these drives is the decoupling of the crank and motor shaft. As a result, there is no pedalling resistance when you ride faster than the maximum supported 25 km/h (without tuning).
Meanwhile, there are already several generations of Specialized drive units that have been continuously optimised by the manufacturer. The company's most important drives currently include the Specialized 1.2 E (50 Nm), which has been optimised for particularly low energy consumption, and the more powerful Specialized 1.3 with powerful 90 Nm. A real power pack is the extremely light Specialized 2.1 motor, which is completely designed for use on e-mountain bikes. It also has 90 Nm and can boost the rider's pedalling power by up to 410%. The Brose Drive S Mag motor serves as the basis, but it has also been equipped with its own software. All Specialized Turbo Levo FSR models have been equipped with this drive since the model year 2019.
Tuning solutions from different manufacturers are available for Brose Specialized motors, e.g. from PearTune, Badass Box, SpeedBox, and the Sx2 Dongle. You can order the most recommended tuning tools for Specialized e-bikes here.
