It makes claims that can't possibly be true, such as "weighs no more than a conventional wheel". I'm not thrilled that there's a gear around the inside perimeter of the wheel either. Seems like debris would constantly be crunched in there.
The Edison in-wheel suspension was not a good idea. It adds to unsprung weight needlessly and compromises the length of travel. Conventional suspension is pretty good. It didn't really solve any problems.
That's the whole thing, a new product must solve a problem better than any other existing products.
