    摘要： A three-wheeled vehicle having a front body member carrying the front wheel and seat, pivotally connected to a rear body member carrying the rear wheels and handlebar. The pivotal connection is designed to pivot the front body member around a pivotal axis that is projected upwardly and rearwardly at a location rearward of the front wheel whereby pivoting produces sideward and rearward tilting of the front wheel and opposite turning of the rear wheels. Steering is achieved by such pivoting of the front body member which in turn is achieved by a sideward swinging of the seat that is positioned between the two pivotal connections. The rear wheels are preferably canted to provide increased stability for the vehicle as it is maneuvered through a turn.

    摘要： A hand-powered vehicle with a device for positioning the crank arms so that the rider can easily adjust them for both vertical and horizontal movement and placement. A device for supporting the rider's legs and feet that combines both a leg support and footrest that can be adjusted forward and rearward relative to the front wheel to accommodate different rider leg lengths. A device for triangulating the frame behind the seat in order to increase frame rigidity between the crank arms and the seat back. A self tightening seat with fabric attached in such a manner that the rider's weight holds the seat frame attached to the frame of the cycle. A device for quickly removing and replacing the rear axle while maintaining proper toe in and toe out of the rear wheels. A device for lowering the structure of the frame below the axis of the front wheel for the purpose of lowering the center of gravity of the bike and rider.

    摘要： A three-wheel vehicle having front and rear frame sections supporting a single front wheel and a pair of rear wheels respectively. The frame sections are pivotally interconnected about an inclined axis defined by a front lower and rear upper pivotal connection. The upper pivotal connection is provided on a swivel bar which is pivotally connected to the rear frame section for swivel pivoting of the pivotal connection defining the inclined axis. A seat on the front frame section positioned substantially above the swiveled pivotal connection is shifted from side-to-side with the pivoting of the swivel bar and inclined axis. A handle from the swivel bar enables a rider to control the swivel bar for shifting of the rider's weight and increased or decreased articulation of the vehicle frame and thus turning of the vehicle to thereby increase or decrease the turning that is induced by pivoting of the front frame section about the inclined axis.

    摘要： An apparatus permitting a user to perform a simulated bicycling exercise is provided. The design includes a frame having a head tube, a first upper rear mounting point and a second lower front mounting point configured to maintain the frame, a seat connected to said frame and configured to support the user in a forward facing orientation, a wheel positioned in association with said frame and pedals configured to interact with said wheel, and a stem connected to a handlebar arrangement, the stem passing through the headset collar and connected to a base by a connection arrangement comprising an arm. The frame is configured to pivot about the first upper rear mounting point and second lower front mounting point in response to leaning by the user, causing rotation of the stem within the head tube by movement of the connection arrangement comprising the arm.
