ABSTRACT:
An oscillating pedal type bicycle is provided with a pedal lever having a front pedal supporting portion and a rear power transmitting portion which are rigidly connected together and which make an oblique angle with respect to one another, with the apex of the oblique angle pointing downwardly and to the rear in the intermediate position of the pedal levers. The two pedal levers each have an intermediate pivot point which is generally under the seat of the bicycle, with the rear end of the pedal lever near the driving hub of the bike and the front end of the pedal lever supporting pedals and being located close to the position of the pedals in a conventional bike during the power stroke. The front portion of the pedal lever between the pivot point and the pedal may be bent to increase the length of the stroke. The power ratio of the bike may be varied by varying the position of the driving chain, belt or other flexible member connected to the bicycle hub, along the length of the rearwardly extending portion of each of the pedal levers. A chain positioning slider on each of the rearwardly extending portions of each pedal lever may be unlocked and moved along the length of the pedal lever by remote control operated from the handle bars or front portion of the frame of the bicycle. Each pedal lever is coupled to the driving hub of the bicycle by separate clutches for independent pedal operation.
