A unicycle is a one-wheeled human powered vehicle. Unicycles are similar to, but less complex than, bicycles.
Construction
Unicycles are composed of a few key parts: the wheel, which includes the tire, tube, rim, spokes, hub and axle; the cranks and pedals; the frame; the seatpost; and the saddle. The wheel is the main part of the unicycle; it is usually a bicycle wheel rim and spokes with a special hub that doesn't freewheel, which means the axle can't turn independently of the hub. This makes it so the rotation of the cranks directly control the rotation of the wheel. This is called direct drive. The frame sits on top of the axle, and cranks attach to the ends of the axle. The seatpost links the frame to the saddle.
Some modern unicycles use gears in the hub to increase riding distance, but the basic construction remains the same; the seat is located on the frame and the frame sits above the wheel.
