Abstract:
An aqua bicycle for submergence into a swimming pool, comprising:a frame; a seat; a pedal mechanism mounted to said frame for rotatable motion; a seat post mounted for height-adjustable slidable motion relative to the frame whereby an adjustable mechanism is provided to vary the distance between the seat and the pedal mechanism to accommodate a length of a user's legs; a leg positioned below a center of gravity of said pedal mechanism and configured to rest on the bottom of the swimming pool, the leg supporting the aqua bicycle away from the bottom of the swimming pool; a rear shaft; a set of blades mounted for rotation about the rear shaft; and a cascade of co-linear pinions positioned between said pedal mechanism and said rear shaft to inter-engage each other and drive said set of blades into rotation in response to rotation of said pedal mechanism and without the use of a belt, a screw jack for adjusting the height of the frame, the screw jack being operatively connected as a second adjustable mechanism to adjust the frame relative to the leg and thereby to vary the position of the seat relative to the water level of the swimming pool and permit a user to breath while in a seated position on the aqua bicycle, wherein said frame is adjustable to support the aqua bicycle such that said set of blades is submerged in the swimming pool.
