Abstract
A self-propelled exercise device such as a bicycle includes a frame having a drive wheel rotatably supported thereupon. The bicycle includes a first and a second foot link which are powered by the user. A coupler assembly directs the first end of each foot link in an arcuate path of travel, and a foot link guide directs the second end of each foot link in a reciprocating path of travel. A power transfer linkage is in mechanical communication with the coupler assembly and with the drive wheel. When the device is in use, a user's foot disposed upon the foot link travels in an elliptical path of travel and provides power to the foot link. This power is transferred to the drive wheel by the power transfer linkage so as to propel the bicycle.
