The new product seems to rely only on axle clamping friction to react the reverse torque of the stator gear, which is a technique known in engineering as "winging it"

At 3:36 in the video you can see that the through-axle has a long splined section, which looks like it might engage with splines in the dropout and the planetary gear system (visible at 4:06 and 8:15), locking them together.

So you also need a proprietary frame 🙂

Yeah, I couldn't work that out. I know nothing about through-axle frames, but that one appears to have an insert on the NDS that forms the dropout. Is that not normal?
