A monowheel is one big wheel with the rider and engine inside the circumference. It differs from a unicycle which has the rider above the wheel. The first known patent was issued to Allen Greene and Elisha Dyer of Providence, Rhode Island in 1869. The idea of a single wheeled motorcycle has captured the imagination of designers for nearly 150 years, and while many have experimented with the format, the idea has remained a novelty. Before you is a Mclean wheel. Kerry Mclean began experimenting with single wheeled motorcycles in the mid-1970s and has spent over 30 years perfecting his monowheel. The monowheel depends on a gyroscopic effect to keep it upright. Much like a bicycle, the wheel is unstable at slow speeds. At 15 mph, you can put your feet on the footpegs. Turning is accomplished by leaning. Learning to ride takes patience and practice.
