ABSTRACT:
A two wheeled human powered vehicle, having a frame with seating arrangement resembling a long wheelbase recumbent bicycle. The drive mechanism includes two parallel operating lever arms supporting a steering assembly on their upper end, fulcramed in the middle, and operably connected at their lower end to a linearly reciprocable footrest assembly. The operator forces the footrests forward directly with the legs while assisting with the arms by drawing the handlebar, thereby providing a rowing motion that utilizes arm and leg power independently. Linear motion is converted to rotational motion and power is transferred to the drive wheel via a jackshaft, including an overrunning clutch, along with a sprocket and an endless chain, operably connected to the drive wheel. Steering is accomplished through flexible sleeved cables, controllably connecting the handlebar to the front steering fork.
