The Boston brings back the basics as the first single speed folding bike with standard 700c wheels. The flip-flop hub allows the rear wheel to operate as either a free-wheel or fixed-gear setup with both cogs included. The Boston is quick and lightweight for the rider who wants simplicity and excellent performance. The patented folding system converts this bike from full-size to trunk-size in less than 20 seconds.
