Abstract:
1. A vehicle configured for conversion between expanded and folded arrangements, comprising: a front wheel having a circumference defining a front vertical longitudinal plane and an axle defining a front vertical transverse plane orthogonal to the front vertical longitudinal plane; a rear wheel assembly including a rear wheel having a circumference defining a rear vertical longitudinal plane and an axle defining a rear vertical transverse plane orthogonal to the rear vertical longitudinal plane; a main frame member having forward and rearward portions extending between the front wheel and the rear wheel and including, for receiving a steering tube, a head tube formed at a distal end of the forward portion and, for receiving a seat post, a seat tube formed at a distal end of the rearward portion; a hinge coupling enabling relative pivoting of the forward and rearward portions about a main frame pivot axis extending at an acute angle relative to the rear vertical transverse plane and at an acute angle relative to a horizontal plane orthogonal to both the rear vertical longitudinal and rear vertical transverse planes; and a rear wheel assembly hinge configured to allow the rear wheel assembly to pivot relative to the main frame member within a vertical plane coincident with the rear vertical longitudinal plane; wherein the front vertical longitudinal plane and the rear vertical longitudinal plane are spaced apart and approximately parallel, in the folded arrangement.
