Abstract: A collapsible cycle for use by a rider over a terrain surface comprises a frame having front and rear portions and a seat attached to the frame. A front wheel is rotatably attached to a steering member, the front wheel rotatable in a first plane about a primary axis, and the steering member being pivotally attached to the front frame portion for rotation about a secondary axis orthogonal to the primary axis. A user-operable steering mechanism is coupled to the steering member. A rear wheel is rotatably attached to the rear frame portion and rotatable in a third plane about a tertiary axis. A drive mechanism is operatively coupled to the front and/or rear wheel. The cycle is collapsible from an erect riding configuration to a collapsed configuration by repositioning the front and rear wheels into mutually closer proximity.

Abstract: A cycle (1) for use by a rider (11) over a terrain surface (36). The cycle (1) includes a frame (2) having front (3) and rear (4) portions; a seat (13); a front wheel (5) rotatable about a primary axis (17) and attached to a steering member (7); a steering mechanism (8) coupled to the steering member (7); a rear wheel (6), rotatably attached to the rear frame portion (4); a drive mechanism (21 or 88) operatively coupled to the front (5) and/or rear (6) wheel; at least one footrest (12, 92) on the front wheel (5). The steering member (7) is pivotally attached to the front frame portion (3) for rotation about a secondary axis (15) orthogonal to the primary axis (17). The cycle (1) is configured such that a rider (11) can be seated on the seat (13) in operative contact with the steering mechanism (7) when the cycle (1) is in motion, while permitting both feet of the seated rider (11) to reach the terrain surface (36) when the cycle (1) is stationary.
