ABSTRACT:
The invention relates to an improved pedal drive mechanism for a bicycle. The mechanism provides a vertically oval pedal path which provides an improvement in the thrust imparted to the driving wheel during the downward movement of the pedal. These paths are defined by two sets of sprockets disposed in parallel planes connected by a set of double strand chains. This mechanism is connected to the drive wheel by a conventional sprocket-chain linkage.
