This article is incorrect. Brose Mag S on Levo puts out 565 watts peak mechanical watts (actually is upto around 750 watts electrical power).Let's have a look at the performance charts. Both motors nominally require 250 watts of continuous power - that is the legal regulation. Does that also mean that the motors are all the same? No. You have to know: a pedelec motor is not regulated in terms of its peak performance. So north the 2020 Bosch CX with approx. 550 watts peak power on paper more power than the Brose DriveS with its just over 500 watts. In practice, these numbers can also be "eaten" by the tires. The wrong air pressure in the tire alone can make a difference of up to 40 watts. A small victory in the quartet for eMTBers is achieved with the Brose in terms of torque: there it is 90Nm to 85Nm for the Bosch CX Generation 4. But: what are these numbers in practice?

Shimano is 500 watts peak confirmed by Shimano engineers to me in person.
