A vehicle configured for conversion between expanded and folded arrangements, comprising: a front wheel (111) 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 (109) 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 (102) having forward and rearward portions extending between the front wheel (111) and the rear wheel (109) and including a head tube (104) formed at a distal end of the forward portion and a seat tube (105) formed at a distal end of the rearward portion; and a hinge coupling (103) 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. |
