Patent ID: 7938419

Claim:
A standard-sized bicycle comprising: a main frame; a seat attached to the main frame for supporting a rider of the bicycle; a front wheel steerably mounted to the main frame; a rear drive wheel rotatably mounted to the main frame; and a rowing mechanism coupled to the main frame about a fulcrum, said fulcrum allowing said rowing mechanism to oscillate forward in response to a pushing force and backward in response to a pulling force, the rowing mechanism comprising: a power lever with a handle on one end and having a second end; and a pair of drive levers extending from the second end of the power lever, each of said pair of drive levers being in mechanical communication with the rear drive wheel such that both a forward oscillation of the rowing mechanism and a backward oscillation of the rowing mechanism drive the rear drive wheel in a same direction of rotation to propel the bicycle forward, wherein said pair of drive levers comprises: a pull-motion lever extending in a forward direction from the second end of the power lever; and a push-motion lever extending in a backward direction from the second end of the power lever.
