1. A collapsible cycle for use by a rider over a terrain surface, said cycle including:
a frame having front and rear portions, said cycle frame including:
a longitudinal axis coincident with a second plane orientated substantially vertically, passing through a forward and rearward direction of cycle travel, anda lateral axis orthogonal to said longitudinal axis, and; a seat attached to the frame; a front wheel rotatably attached to a steering member, said front wheel rotatable in a first plane about a primary axis, said steering member being pivotally attached to the front frame portion for rotation about a secondary axis orthogonal to said primary axis; a user-operable steering mechanism coupled to said steering member; a rear wheel, rotatably attached to the rear frame portion and rotatable in a third plane about a tertiary axis; a drive mechanism operatively coupled to the front or rear wheel; said cycle defined volumetrically by mutually-orthogonal parallel-pairs of vertical and horizontal planes (when the cycle is positioned upright), demarcating opposed longitudinal, lateral and vertical boundary planes, respectively located at longitudinal, lateral and vertical extremities of both said cycle and front wheel, rear wheel and frame individually, said cycle collapsible from an erect riding configuration to a collapsed configuration by repositioning said front and rear wheels into mutually closer proximity, and characterized in that said steering mechanism includes a pair of handlebars displaced from the secondary axis by a stem, the stem extending from the steering member rearward and below the seat. |
