A recumbent electrically power-assisted bicycle which permits a shortened wheelbase by positioning the rider in an adjustable seat above the rear wheel. The battery, motor, and controller comprising the power assist system are mounted at the front of the bicycle's frame so as to provide stability, and also provide power assist to the bicycle under startup and high pedalling load conditions.

The present invention relates to a recumbent exercise apparatus that provides elliptical foot exercise with arm exercise. More particularly, the present invention relates to an exercise machine having separately supported pedals for the feet and arm exercise coordinated with the motion of the feet. The pedals articulate to provide lower leg exercise with the heel and toe remaining in contact with the pedal while the pedals move along an adjustable inclined elliptical pedal curve. Arm exercise is...

A recumbent cycling apparatus includes a foot support which moves through a substantially elliptical path of motion relative to a frame. A seat is movably mounted on the frame to facilitate adjustment of the seat relative to the foot support.

A two wheel semi-recumbent bicycle provided in several embodiments on which the rider sits elevated above the rear wheel on a high-back bucket style seat supported by an angled top tube. The position of the pedal crank assembly is forward and upward of the pedal crank position of conventional bicycles and downward and rearward of that normally associated with fully recumbent bicycles relative to the seat. The rider steers by way of long upwardly curved handlebars affixed to an elongated steering...

A recumbent exercise cycle comprises a pair of pedals and a seat which are each individually adjustable relative to a crankshaft that is rotatably mounted on the frame of the exercise cycle. In combination, each pedal is connected by an extension arm to a point on a crank arm for movement of the pedal along a circular path about the point on the crank arm, and the crank arm is connected to the crankshaft for movement of the point along a circular path about the crankshaft.

A tilt steering mechanism facilitating a large degree of rider position adjustment is provided for use in connection with a short wheel base recumbent bicycle. Bicycle comprises a front steerable wheel, and a foot pedal driving mechanism rotatably mounted to a frame such that the axis of the foot pedal driving mechanism is located forward of the rear most point of the front steerable wheel. A tilt steering mechanism rotatably mounted to a frame and located rearward of the axis of a foot pedal dr...

A recumbent vehicle including parallel paired recumbent bicycles operatively and reversibly joined by a bracing assembly having less than four brace members, is provided. The parallel paired recumbent bicycles are easily separable, without the need for tools, for individual riding. A conversion kit for reversibly uniting a pair of recumbent bicycles so as to form a recumbent quad is similarly provided. The kit generally includes a bracing assembly including a pair of braces, and brackets adapted...

A recumbent bicycle, the manufacture thereof, and apparatus for forming same, is provided. The recumbent bicycle generally includes a frame having joined forward and rearward frame portions. The forward frame portion is a sit-up bicycle frame adpated to support a steerable front ground engaging wheel. The rearward frame portion is adapted to support a suspension assembly and substantially bear a rider thereon. Preferably, the sit-up bicycle frame includes a head tube, down tube, bottom bracket, ...

A recumbent cycle with improved steering and drive assemblies is provided. The recumbent cycle is of the tricycle type having two rear wheels spaced-apart and rotatably supported on an axle and a single front wheel. A frame assembly, including a seat disposed in a recumbent position and fixed to a tubular frame, is pivotally attached to the axle, and includes a forward mount for rotatably supporting the front wheel. A pedal/crank drive is included for rotating the front wheel and, therefore, pro...
