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.
