Abstract

The bicycle transmission reduces the driving force without affecting that applied to the wheel. It has a primary lever (1) to which the effort is applied, and whose length is four times that of normal pedal cranks, and equipped with a pedal (11). This transmits the power to a secondary lever in the form of a calliper-type knuckle joint (4, 4'). The primary lever can be attached to a bracket (2) on the chassis, and there can be an eccentric roller (3) connected to the lever and to the knuckle joint, and forced by a guide to turn as the result of the knuckle joint arms moving apart.
