Abstract

See full text

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.
