The wheels are apparently really really loud when they are mounted like this. You just can make good enough ball bearings of this size at any reasonable cost and weight

*The coolest looking concept bike ever created.

Lemmings: hold my beer while I list every complaint I can think of about this design

Yeah why do we need another bicycle?

Also how does peddling move the wheels...? Missing something.

You could also cover the spokes or use a spokeless single wall design. I do think a design like this would need to be cleaned a lot.

Ok, maybe with a magnetic linear drive?

Is this an AI bicycle or a Dyson bicycle?

Is there any regime where this is more efficient than spokes? I'd imagine that at high speed there's an aerodynamic advantage (possibly similar to a track/TT disk wheel?), but I can't imagine the bearings being better than current bikes. But bearing loss might (???) just scale linear with speed, so probably a win from aero in the end. But this isn't counting weight, which I imagine is worse (but doesn't matter much at high speed on flat ground).

Needs blue or orange neon lights

Nah; you just have to jam the stick through the tire itself so it gets caught at the part that is spinning the wheel.

The complexity of this design cannot be outspoken.
