The bicycle transmission system, with pedals, a chain and sprockets, has the pedals (2) pushed in a reverse direction to propel the bicycle forwards. The effort of the pedals is transmitted through cranks to a pair of meshing gears (1,5). The clockwise rotation of the first gear, (1) when viewed from the left-hand side of the bicycle, causes the second gear (5) to rotate in an anti-clockwise direction. This second gear carries a sprocket (9) which is connected by a chain (6) to a driven sprocket (7) on the rear wheel. The gear and sprocket sizes are selected according to the gear ratio required.
