  • Gearing mechanism for high speed bicycles
    Patent number: 5285701
    Abstract: A bicycle is provided that has a frame with a seat tube and a down tube aligned in the same plane, a chain stay rail, a free wheel mechanism and a crank hub. The bicycle is improved by having an enlarged crank sprocket rotatable in a plane substantially parallel to bike frame and able to provide a gear ratio of at least 4.5 to 1 with respect to the free wheel mechanism. The crank sprocket is stabilized to prevent it from wobbling and to maintain its rotation in a parallel plane. The crank sprocket is also extended away from the hub to allow the crank sprocket to rotate without coming in contact with the chain stay rail. Preferably, the crank sprocket can provide a gear ratio of 6.5 to 1 with respect to the free wheel mechanism and has a plane of rotation located at about the center of the axial width of the free wheel mechanism.
