>Interesting. But not my style of bike - and I see they are (at least currently) only intended for this compact type. Also looks like they may be quite heavy compared to carbon fibre (or traditional spoke wheels).

With larger diameter wheels (i.e. 700c) I'd be concerned about lateral stiffness, too. Also since the ends of each loop are offset horizontally I wonder if there would be any weird handling effects. Not to mention aerodynamics - these days aero rims with low spoke count/bladed spokes are pretty hard to beat. Sure there's no suspension but people riding those wheelsets are willing to suffer a bit for speed :)

The Loopwheels do look interesting for the folding/commuter bike market. Still, I wonder how much improvement the rider sees over, say, a suspension seatpost.
