Definition

Noun: A coaster brake is a type of brake system for a bicycle. It is activated by applying backward pressure on the pedals, which causes the rear wheel hub to engage a braking mechanism, slowing or stopping the bicycle.

Usage

The term coaster brake is used to specifically describe this internal hub braking system, distinguishing it from hand-operated rim or disc brakes. * It is most commonly found on single-speed or cruiser-style bicycles. * The phrase is typically used in a technical or descriptive context when discussing bicycle components, maintenance, or features.
