Unicycles have a few key parts:

* The [[wheel]] (which includes the [[Bicycle tire|tire]], tube, rim, spokes, hub and axle)
* The [[Crankset|cranks]] (which attach the pedals to the wheel hub)
* The hub (connects the spokes to a central point and also transfers pedalling power to the wheel)
* [[Bicycle pedal|Pedals]]
* [[Bicycle fork|Fork]]-style frame
* [[Seatpost]]
* [[Bicycle saddle|Saddle]] (the seat of the unicycle)

The wheel is usually similar to a [[bicycle wheel]] with a special hub designed so the axle is a fixed part of the hub. This means the rotation of the cranks directly controls the rotation of the wheel (called [[direct-drive mechanism|direct-drive]]). The frame sits on top of the axle bearings, while the cranks attach to the ends of the axle, and the seatpost slides into the frame to allow the saddle to be height adjusted.
