Wonder how this works, how you change a tire, how the rim stays true without spokes, and how much heavier it is than normal. Also, I wonder if unis will ever go “hubless” one day. 
And here’s a bike prototype. Seems to me that if the wheel got tweaked or even slightly out of true, it wouldn’t spin very well.
I saw a motorcycle like this mentioned in this thread about spokeless bicycles.
It seems to me that this would work a lot like the monocycle does.
I just did a search on “how monowheel works” and came up with this and this.
It’s pretty interesting. It seems like the inside rolls along a track that’s on the outer wheel (If you accelerate/decelerate to fast, you rotate/tip forwards/bckwards). A hubless might work like that except that the inside is held down more rigidly.
It’s probably more accurate to say that the whole wheel is one large hub.
Yes, but then it would be broken. A spokeless rim does not function like a spoked rim in that it is not treated as an elastic form under tension. The rim itself is instead a rigid mass, just like a frame. Bend it and it’s bent.
artsy, not pragmatic
I am seeing a huge bearing, with a huge seal, that would screw up fast in the real world, being a hugely expensive POS to repair.
Normal center of the hub bearings are cheap. I think it is only artsy designers that like the rim bearings. Not cheap, also, huge seals, and roller speeds (inside the bearing, because they are at the high speed outer part of the rim).
These things can be made to work, but they are like designer handbags. The only thing they are better at is showing other riders they can’t afford to piss money on flash like you can.
They have a place on “show not go” choppers, but physics argues against the idea for any practical purpose.
