it certainly looks weird and I can totally see why anyone would question it. I’ve watched it several times and feel that just before he unclips the wheel ought to be all but stationary as it’s dragging on the floor. At best it ought to be travelling at crash speed which I’d not expect to generate the kind of radial acceleration seen.
What could be the reason it looks so unnatural is the orientation of the whole bike. @ 7 seconds you can clearly see that the whole bike seems to be supported on both front and rear wheels rather than the handlebar, pedal and rear wheel you’d normally expect. I’m wondering if this combination and the slope combines to give it a weird look.
