ABSTRACT:
An upright in-line cycle having a frame, front steerable wheel, drivable rear wheel, drive sprocket, driven sprocket, oscillatory steering levers, a fork assembly, a drive crank assembly, and drive with connecting rods operably connected such that the oscillatory levers are pivotally mounted on the fork joumaled to connecting rods such that the oscillatory levers are substantially perpendicular to the connecting rods and the connecting rods are substantially parallel to the plane of the ground. The oscillatory levers and connecting rods are operably connected so that the alternate pushing or pulling on the oscillatory levers drives the cycle forward, convening upper body energy into rotational energy. The manner in which the oscillatory levers are journaled to the forward end of the connecting rods, by tie rod ends or two-way joints, permits the levers to pivot in a lateral left or right direction thereby permitting steering of the front wheel. The front and rearward ends of the connecting rods are provided may be removed either through an open ended shape or with a quick release to allow the connecting rods to be disconnected and removed. The oscillatory levers can then be clasped together with a ridged member so that levers no longer oscillate and the bike may be ridden as a lower body powered cycle, as in a conventional cycle.
