    1888 Geared Facile Bicycle in the Coventry Transport Museum A chain-drive and rear gear hub A bicycle gearbox with chain tensioner A penny-farthing with direct-drive. A cyclist's legs produce power optimally within a narrow pedalling speed range. Gearing is optimized to use this narrow range as best as possible.

    Chain tensioner on a single-speed bicycle Belt tensioner on a belt-drive bicycle Hydraulic bolt tensioner Hydraulic Puller-tensioner . A tensioner is a device that applies a force to create or maintain tension. The force may be applied parallel to, as in the case of a hydraulic bolt tensioner, or perpendicular to, as in the case of a spring ...

  5. Derailleur - Wikipedia

    en.wikipedia.org/wiki/Derailleur

    Sometimes the rear derailleurs are re-purposed as chain tensioners for single-speed bicycles that cannot adjust chain tension by a different method. Although variations exist, most rear derailleurs have several components in common. They have a cage that holds two pulleys that guide the chain in an S-shaped pattern.

    en.wikipedia.org/wiki/Single-speed_bicycle

    The Flying Pigeon PA-02, a single-speed utility bicycle, is the most produced bicycle model in history. A single-speed bicycle is a type of bicycle with a single gear ratio. These bicycles are without derailleur gears, hub gearing or other methods for varying the gear ratio of the bicycle.
