Did anyone see "The great biker build off" programs?
One of the builders has a couple of bikes with "hubless" rear wheels. Although they are not true hubless designs (they are massive swingarms with the wheel centres milled out), I think they look fantastic.
You can see them on this site -

I'm not really one for choppers, but this detail really stood out and got me thinking. What would it look like on a sportsbike and how much would it cost??!!
