Get rid of those troublesome hubs!

[Woosh]

I wonder what sort of ride you get from it. I notice in the videos that the riders don't seem to want to put their bum on the saddle. It reminds me of the Mercedes Smart bike, which wasn't too bad apart from comfort. It was just too stiff, so you felt every bump. This one must be even stiffer because there are no spokes and a very short rigid fork. Also, the riding position looks a bit hunched. I can't see any provision for adjusting anything other than seat height.

There is no lateral support to the rims, no load distribution.
I would also like to see what will happen to the wheels if that guy hits a kerb or a pothole.

They'll disappear as soon as the warranty claims start coming in.

I will stick to my trouble free (except for the odd maintenance every 3 - 4 k + miles, reliable, lighter and easy to diagnose faults and likely at a much cheaper price.

There will be quite a ew places you can't take it without the wheel breaking up, first jump or down a rough D/H track and it will be a pile of scrap.

Like on any road for a few miles.....

That's a good point. The spokes resist any forces that try to bend the rim inwards. I can't see how those spokeless rims could be stiff enough without being too heavy.
