What do you get when you take the simplicity and novelty of a unicycle and throw a second wheel and set of handlebars on it? You get what you see in the images above, the Bicymple bike. In stripping the bike of a chain and putting the pedals directly on the rear wheel, much like a unicycle, and installing an overdrive hub system, the Bicymple essentially provides you with the fixed-gear experience, sans some complicated components, and allowing for an awesome degree of maneuverability.
