Brose S-Drive

With a whopping 90Nm of torque on tap it has the Brose S-Drive motor has a huge power advantage over its rivals.

The beating heart of this BULLS is the peerless BROSE S-Drive. For 2018 the Brose has new software giving more low-speed torque and smoother power delivery across all speed ranges. Its main ingredients are aluminum, magnesium, experience, enthusiasm and …helical epicyclic gears! All Brose motors are designed and manufactured in Germany.

Where other well known e-bike motors are built to a price point, the Brose S-Drive is designed and manufactured to a quality standard, incorporating precision engineered helical epicyclic gears. These are much more expensive to manufacture but offer dramatic performance and wear rate improvements over the cheaper spur gear tooth profiles that the competition use.

In the simplest terms spur gears transfer power from the driving gear to the driven gear via only one or two teeth at a time, whereas with helical gears power is transferred by three connecting teeth at a time. This results in less wear, less noise, less friction and a smaller and lighter drive unit.

Despite its small physical size the BROSE S-Drive produces a market leading 90 newton meters of torque. It does this quietly, reliably and without fuss. The company’s sensor concept is the only one of its kind on the market today: it measures rider pedal force no fewer than 420 times a second, delivering smooth, vibration free assistance. Production began in July 2014 and by August this year the Rotwild/Brose test team had covered 69’445 miles ofBrose e-bike motor shaftarduous Alpine trails.

Their annual turnover exceeds €5 billion. Last year Brosemanufactured 100 million electric motors. They know what they’re doing.

Decades of experience specialising in mechatronic systems for the automotive sector mean they’re perfectly placed to produce this innovative e-bike drive unit. Development and production of the Brose e-bike motor is carried out entirely in-house at their Berlin engine plant, where a dedicated team of engineers design, build and test the system at their purpose built e-bike center of excellence.
