Just how practical are the many variations of spoke-less wheels shown in various bicycle and motorcycle designs? They look great. Do they work well in practice?
Perhaps spokeless bicycles are safer, meaning that there is nothing that could get caught in there and get it stuck. I'm sure it's also light with fewer parts and no messy chain (but you get messy gears instead).
I repeat: There is more to designing than dreaming.
1) There is no stable arrangement of magnets to support a static object. Physicists prove these sorts of things to show off their stuff.
2) When that top part flips over and the magnets attract, and then get much closer together the occupant is going to end up as a red stripe around the perimeter of the room.
Unrelated blabbering: Wheels without spokes I can live with, but wheels with three or so spokes look quite dangerous. The nice things about spokes is one comes along to whack your body part out of the opening before you get so far in that physics takes the easy way out and chops off the body part instead.
