Why not go with the Windsor Clockwork Plus over the Hour: Save Up To 60% Off Windsor Fixie Singlespeed Bikes - Clockwork

It's a little more than the Hour but still way less than most complete bikes, available in a lot more size and color options, comes with a slightly nicer looking crankset, and two decent brakes installed with hoods and levers. Personally I can't stand riding with drops on the street without hoods, so that's worth the extra $80 for sure.
