A human-powered recumbent tricycle with an articulated frame that permits leaning of the single-wheeled front sub-frame (10) during turns. While the seat (20) and pedal crank (18) move the driver's body with the leaning front sub-frame (10), the two-wheeled rear sub-frame (71) carries the handlebar (90) for optimum driver control of vehicular orientation. Steering of the front wheel (16) is accomplished by two cables (60L, 60R) within housings (61L, 61R) that provide immunity from distortions ca...

A recumbent apparatus for exercise and physical therapy providing a lower body workout, an upper body workout and cardiovascular conditioning, the apparatus comprising a frame having a forward end and a rearward end, the frame generally defining a longitudinal axis extending between the forward and rearward ends, a seat supported by the frame, a left leg assembly and a right leg assembly, the leg assemblies supported by the frame for pivoting movement about a pivot axis transverse to the longitu...

A recumbent exercise device which provides lower body, upper body and cardiovascular conditioning. The device includes a frame having a seat supported toward the rear thereof. A pair of leg assemblies and a pair of arm assemblies are pivotally supported by the frame for movement about a transverse pivot axis. The arm and leg assemblies are positioned generally toward the forward end of the frame and each includes an upward and forward extending lever with the leg assemblies terminating in pedals...

A recumbent bicycle designed to be flexible in its geometry, adjustable in wheel base, position of seat, position and angle of front fork steering head tube mechanism, lead of front wheel bearing position on front fork, and/or position of foot pedal crank mechanism, allowing ergometric optimization for riding ease, comfort, stability, safety, etc. The unique aspect of the present invention is that the relationship between the bicycle seat and the rear wheel can be ergonomically optimized, and th...

A dual recumbent vehicle is provided which includes a pair of recumbent bicycles interconnected in a side-by-side relationship. Each bicycle has an operator controlled steering assembly, an operator controlled drive assembly, and a recumbent seat operatively connected to a frame structure. Each of these bicycles is further connected by cross-braces for operatively connecting the bicycles in a side-by-side relationship, and a steering coupler for coupling the steering assemblies of each of the bi...

A recumbent tricycle which includes a propulsion system which includes a combination of foot and arm power for propulsion. Pedals are operated with the rider's legs. Handles are also connected to the drive mechanism, with the handles pulled back and pushed forward to add to propulsive power. The handles are also connected through a tie rod arrangement to the front wheels such that the wheels may be turned so that the vehicle can be steered by moving the handles toward one side or the other. Pref...

A linear drive recumbent cycle (10) having linearly reciprocating pedals (68a,b) located approximately above the front wheel (14) in order to achieve a short wheel base recumbent bicycle design with the crank (42) located low between the wheels and with the seat located near or behind the center of gravity of the bike. The top extremities of a pair of pedal sliders (32a,b) are journalled for independent pendulum-type oscillation in a pedal-slider bracket (28) which is connected to a frame (12) t...

A short wheel base, three wheel recumbent vehicle comprising a main frame including a plurality of tubular members assembled in truss like fashion. A single rear drive wheel driven by a multi-speed chain drive pedal crank assembly mounted on extended front frame to provide clearance for riders feet. Two front steerable wheels positioned with foreshortened wheel base are rotably mounted to the main frame and actuated by tie rods from a center pivot plate connected to a steering bar to provide sho...

A longitudinal frame supports a seat whose longitudinal position on the frame is adjustable. A pair of footbeams are mounted on either side of the forward end of the frame near the floor and extend generally upwardly. The footbeams independently pivot on the frame so that the user can operate them in an alternating reciprocating fashion. Pivotal movement of the footbeams by the user is resisted, thereby requiring the user to expend energy in operating the device. The footbeams are preferably int...

A recumbent bicycle frame having a frame tube with a first shoulder area formed on a side thereof. The shoulder area extends for at least a portion of the length of the frame tube. The frame tube has a generally flat exterior surface above the first shoulder area. The frame tube also has a second shoulder area formed on an opposite side of the frame tube from the first shoulder area. The frame tube has a bottom shoulder area formed on the side of the frame. A generally flat exterior surface exte...
