Recumbent cycle (12) is supported by a pair of forward steerable wheels (16) and a single rear drivewheel (18) mounted on rear end portion of a frame structure (14) by a hub assembly (50) having an integral transmission and brake. A pair of side-mounted gimbal assemblies (170L, 170R) may be conveniently tilted laterally to steer wheels (16) in the same corresponding direction. The gimbal assemblies (170L, 170R) may be individually or in unison tilted in the forward direction to actuate the brake...

A bicycle operated by a rider in a reclining position. The frame of the bicycle is constructed of a forward section, a middle section and a rear section. The rear section supports the rear wheel and the back of the seat. An X member behind the seat connected to the rear section provides further support for the back of the seat. The forward section is reinforced by a pair of more or less parallel crank assembly braces extending from the rear of the middle section to a crank assembly positioned at...

An amusement tricycle wherein the operator is transported in an inclining position on a hammock cradle. the cradle is carried by a front wheel which does not pivot relative to the cradle. The cradle and wheel rotate about a downwardly sloping axis to turn. The cradle is supported to the rear by a two wheel buggy. The cradle is mounted on the buggy by a pivot. The pivot rotates about the axis. The buggy in turn, is stabilized by pivotal attachment to the cradle.

An improved recumbent bicycle having a carriage unit comprising an improved seat assembly and handle bars. The carriage unit is adjustably mounted on the frame of the bicycle so that it is movable toward and away from the foot pedals in order to accommodate different sized riders.

A rear steered vehicle with improved handling and stability described by having a single front driven wheel and a pair of steered rear wheels. Cornering ability is improved while maintaining a narrow overall width by allowing the rider, front wheel, and frame to lean "into" turns thereby shifting the vehicle's center of gravity to the inside of a turn. Stability at all speeds is improved over other rear steered vehicles by the steering design which rotates the two rear wheels on separate steerin...

A recumbent vehicle comprising a single, bowed tubular member forming a main frame having a front end and a rear end. A rear wheel fork assembly is mounted toward the rear end of the main frame with a rear wheel rotatably mounted in the rear wheel fork assembly. A crank assembly, including crank pedals, is mounted to the front end of the main frame. The crank assembly is adjustable to alter the distance of the crank pedals from the front end. A pair of front steering wheels is rotatably mounted ...

A bicycle having a frame with a single steering arm rotatably mounted in the frame and extending downwardly away from the frame. A wheel support is provided at the end of the arm and a front wheel is rotatably mounted on the wheel support with a single bearing. The bicycle can have a pair of frame arms extending down from the frame with the steering arm between the frame arms and adjacent one of the arms so the front wheel is located between the arms. The frame arms carry pedal means with the ax...

A recumbent vehicle having a frame which includes an elongate tubular support adapted to substantially entirely enclose within its interior the vehicle's primary drive mechanism thereby eliminating risk of rider entanglement. Other features of recumbent vehicles according to the invention include a steering assembly including handlebars selectively positionable along the frame and diametrically interconnected by steering cable means to a front fork selectively positionable along the frame and ro...

A recumbent bicycle includes a seat with a back rest and pedals forwardly of the seat so that reaction from the pedals can be communicated by the rider into the back rest of the seat. A pair of levers immediately in front of the seat can be operated in reciprocal movement to add to the propulsion effort of the pedals with the levers communicating to the chain wheel of the pedals through connecting levers and a further chain wheel. Steering movement is obtained by a common pivotal movement of the...

A recumbent tricycle including a frame, twin rear wheels pivotally mounted to the frame and steerable by a pair of levers pivotally mounted to the frame on either side of a passenger seat. The rear wheels are oriented substantially vertically and are attached to hubs inclined inwardly toward the frame to create a cambered effect which maintains the rear wheels in a forward-facing position as the tricycle moves in a rectilinear path. The single front wheel is preferably driven by a pedal crank as...
