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?

source but in German 🤗

This article is incorrect. Brose Mag S on Levo puts out 565 watts peak mechanical watts (actually is upto around 750 watts electrical power).

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

Yup don't confuse electrical input power to mechanical power output on the power train, heat and friction are a huge user of your battery without any gain to your actual on the ground cycling fun.

Hi Rob, yes fortunately only the Android App is cactus, I borrowed a friends iphone and back in business but yeah Android App is a basketcase.
Such a shame this whole launch has gone so wrong. It does make me question my choice of shimano motor, but I expect all the manufacturers are the same in reality.

Thats part of adopting a relatively new technology I guess!

where is the problem? so far the engine is not in series production and by then shimano will very likely have fixed the rattle.

Despite the construction problem, Brose delivered the S Mag and to this day the motors continue to poop. I really hope that the Levo 3 will come without Brose.

Well, I would say that that pulling the product after (the already delayed) launch isn't ideal and demonstrates a lack of testing / proving of the product, and updating an app which has issues including rendering bikes (albeit reversable) non functional isnt how to cover yourself in glory!

Yes, I agree. Shimano has set himself the Release date of September 1st. It would have been better to wait another 2-3 months. However, there is so much pressure in the market and it is actually quite normal for a new product to be further improved after its launch. It is best to buy a product 2-3 years after its introduction. I just hope that the EP8 doesn't experience such an embarrassing disaster as the Brose S Mag. It remains exciting ...

So I tested a few days after Rob, I rode a few bikes, they all rattled a lot, like a large very loose cable in the frame. Was very annoying. Shimano said they would fix it and listened to our feedback...
