I broke sturmey with a 500W M600 a month ago. That hub is only rated for 80Nm of torque, with peak of 100Nm.
I also spoke with Enviolo - the new 380SE is rated for 100Nm but they dont support torque of the m600 and m620.
Some of you know that I used to race cars. So in regards to the Kindernay shifting, aside from upshifting on the right and downshifting on the left, I'd like to know if the upshift can be a pull (similar to the brake lever) and the downshift remaining a push (as in what most are already used to with the thumb shift).Good question. From what I see, it is just a standard hydraulic cable that you can swap and bleed again .
I’ll confirm with Kindernay though.
Right now both operations are via a "push" action. I am not sure if the newer single hand shifter will have dual action (push / pull).Some of you know that I used to race cars.

Sorry. Quirks of an old hobby being applied to a new passion.
1. This depends on gearing - if riding in the right gear, this will not be a problem (like the rohloff).
2. As is the case with most hubs, this is the max torque rating on the weakest gear.
If you are geared correctly, and are not sending 250Nm of torque via a throttle, you will be fine. We restrict throttle on our bikes to 60-70Nm (~500-600W power equivalent).
I'm still trying to figure out which configuration of this bike I want to purchase. I'd like the configuration with highest top speed that doesn't rip itself apart.
... but ugly ergonomics with the current dual shifters or 3rd-Part twist shifters. Still really loving the different hub options, but really want to see more of these built into a hub motor.When it comes to getting the highest top speed, playing it safe isn't the way... Ya gotta break some eggs to make an omelette and all that
Sounds like the Kindernay has more torque rating, better shifting under (light) load, way better shifting feel, solid compatibility with newer frames (thru-axle), and a great solution to multiple wheelsets.
