Abstract
A velocipede comprising a rigid frame with front and rear wheels and a crank operably connected to the rear wheels. A first member has its front end portion pivotably connected to the frame front end such that the first member is movable between upper and lower positions above and below a horizontal line passing through the pivot. A second member has a first end pivotably connected to the first member rear end portion and a second end pivotably connected to the crank such that reciprocating movement of the first member rear end portion causes the second member to rotate the crank. A third member includes a pivot disposed at its intermediate portion and has its front and rear ends movable between upper and lower positions. A pair of pedals are pivotably secured to the third member front end and movable therewith between the upper and lower positions. A fourth member has one end pivotably connected to the first member rear end portion and a second end pivotably connected to the third member rear end such that when the first member is in the lower position, the pedals are at their upper position and when the first member is in the upper position, the pedals are in their lower position. A seat is disposed intermediate the first member front and rear ends and substantially directly above the third member pivot such that when the pedals are at their upper position, the pedals are slightly forward of the seat.
