Abstract
A transmission for a bicycle having a driver assembly with a torque band, the driver assembly being pivotable about a first axis. A driven assembly rotatable about a second axis, the second axis spaced a distance from the first axis. The torque band is rotatable about the second axis. An input source engaged with the driver assembly such that the input source causes the torque band to rotate about the second axis. The driver assembly principally engages said driven assembly along an engagement path at a first distance from the first axis and at a second distance from the second axis whereby the driven assembly is caused to rotate about the second axis, the second distance being infinitely adjustable throughout a gear ratio range. A rotatable output member is engaged with the driven member wherein rotation of the driven member causes the output member to rotate.
