ABSTRACT:
The hand and foot powered bicycle has an elongated frame supported by a front and rear wheel. A handle bar lever is mounted to the frame adjacent to the steering column such that the handle bar lever may be raised and lowered by moving the attached handle bar up and forward and down and rearward. The handle bar lever is connected to a front sprocket wheel by lever arm linkage attached to sprocket wheel crank arms. This front sprocket wheel is linked to the rear wheel gears by two chain loops and a mid sprocket wheel assembly. With this linkage, as the handle bar is raised and lowered, this motion is translated to rotate the rear wheels. The hand and foot powered bicycle is steered by the handle bar connected to the front wheel forks through a pair of steering cables which are crossed between their abutments to give a correct turn for a turn of the handle bar. Pedals with cranks may be attached to the sprocket wheels as in the conventional manner to provide the combination of hand and foot power for the bicycle.
