  • Patent number: 6773022
    Abstract: A bicycle for providing stair-stepping exercise motion, recreation, and mode of transport comprising a frame that includes a unique triangular rear portion, a pair of wheels, one for the front, one for the back, a chain driven, teardrop-shaped propulsion system, left and right pedals having multiple positions between a horizontal and angular vertical upon which the operator rides, adjustable handle bars for steering, and a safety housing for covering the propulsion and wheel sprockets, chain, braking mechanism, and bike stand. In an alternate embodiment the pedals on each side may be made of telescopic members to provide reciprocal motion so that the forward end of the pedal does not move reciprocally. Also a terrain engaging frame extension is provided below the middle portion of the frame for engaging terrain objects to prevent the pedals from engaging the terrain during activation.
