Abstract:
A collapsible two wheeled vehicle comprising:a substantially rigid unitary main structural component defining a head section for supporting a steerable front wheel, a saddle pillar mount and a bottom bracket rotatably supporting a pedal-shaft;a rear wheel sub-frame pivoted to the main structural component about the axis of rotation of the pedal-shaft and rotatably supporting a rear wheel, the sub-frame being arranged for movement between a folded position where the rear wheel lies within the main structural component, between the head section and the saddle pillar mount, and an active position where the sub-frame projects rearwardly beyond the main structural component;a first drive wheel carried by the pedal-shaft, a second drive wheel connected to the rear wheel, and an endless flexible tension member passing directly round the first drive wheel and the second drive wheel whereby rotation of the pedal-shaft drives the rear wheel;a front wheel carrier journalled to the head section of the main structural component and having an arm rotatably supporting a front wheel, the arm being pivoted to the carrier for movement between a folded position where the front wheel lies adjacent but in substantially the same plane as the rear wheel when the sub-frame is in its folded position, and an active position where the arm projects generally downwardly from the carrier; andthe main structural component carrying paneling comprising two opposed side panels, the paneling being dimensioned so that the folded rear wheel sub-frame, rear wheel, front wheel carrier, folded arm, front wheel and first drive wheel all lie substantially wholly within the confines of the side panels, the rear and front wheels lying outside the confines of the side panels when the sub-frame and arm are in their respective active positions.
