The ratchet and pawl mechanism, a small device inside the wheel hub with slanted teeth and spring-loaded pawls, allows bicycles to coast by enabling the wheel to turn freely while the pedals remain stationary; when pedaling forward, the pawls lock to drive the wheel, but when stopping, they slide over the slanted teeth, creating the characteristic clicking sound that enables coasting.
