The current document is directed to a two-wheeled unicycle that features bicycle-like pedals and a freewheeling mechanism to allow a rider to coast while the unicycle moves forward. In one implementation, he pedals are affixed to a horizontal drive shaft that rotates with respect to the wheels of the two-wheeled unicycle via two ball bearings. The horizontal drive shaft transfers rotational force through a ratchet-based, freewheeling mechanism to a larger-diameter cylindrical shaft to which the two wheels are affixed. The freewheeling mechanism transfers forward pedaling motion to the wheels. However, the wheels can rotate freely in a forward direction even when the pedals are maintained in a fixed orientation with respect to the surface on which the unicycle is traveling or another fixed reference point.
