What are the main components of a bicycle's wheel assembly?

The main components of a bicycle's wheel assembly are the rim, spokes, hub, and tire. The rim is the outer circular part that holds the tire in place. Spokes are the thin rods that connect the rim to the hub at the center of the wheel. The hub is the central part of the wheel that houses the axle and allows the wheel to rotate. The tire is the rubber covering that provides traction and cushioning.
