Montague's Boston bike is unique because it's a full-sized bike that rolls on 700CC wheels. It comes with a flip-flop hub so you can make it into a single speed or fixie. Designed around a patented folding system, Montague touts that it's the strongest folding bike on the market. Definitely one of the coolest bikes on this list, it's a steal under the MSRP of $800.
