$300 · Large Single Speed/Fixed Gear: Redline 925

59cm frame suitable for someone around 6 feet tall, this bike has a flip-flop rear hub that can be converted between a single speed freewheel or a fixed gear. It's got a chain guard, fenders and rear rack if you want to use it as a commuter. Last fall it was completely rebuilt with a new bottom bracket, pedals, handlebar tape, brake cables, chain and seat, so it should require very little maintenance for years to come. It's a fast ride with super comfortable bull horn handlebars.
