materials and design engineering will continue to evolve and you backwater thinking haters will just have to watch.
The next question is does the rim moves or only the rubber tyre(i suppose) moves.If these questions cannot be answered it will be appropriate if the designer keep it as a drawing collection.I sort of agree with Mr. Richard wicks comments.
Otherwise we could all throw the whackiest crap out there and say hey give me kudo's. If this thing has been constructed and tested and does indeed work, well then I stand corrected and say "Rock on wit'yo bad selves!", but I've seen the hubless thing done on so many different sorts of vehichles and it always comes down to the same thing, does it work, is it practical?
This is awesome design! We need more of it!!
You have to design a bicycle and every parts have to be totally different than any well-evolutioned bicycle build tradition. move on!" :P
The whole idea of a hub and tensioned spokes is what makes a bicycle wheel strong. Force is applied perpendicular with the rim of the wheel, and distributed evenly along the entire circumference. Not so with this design.
One pothole or speedbump will ruin the rim.
