The brand new Brose DRIVE S has seen the German brand focus on what’s inside, fitting 16 new electronic parts and really getting a handle on the rest of the complex internal parts. It might seem minor but even swapping a steel screw for a stainless steel one on the circuit board has led to efficiency gains of 1.25% on the DRIVE S. Yet way more than just screws, Brose have fine-tuned the inside of the motor meticulously, resulting in a motor with 15% more power and a more economic ride manner. But going beyond purely technical aspects, Brose also turned their hand to improve its heat dissipation by adopting new seals, and looked for ways to improve the motor’s sensory system too.
