ABSTRACT:
A collapsible bicycle includes a rigid main frame and a collapsible rear frame movable between riding and storage positions. The rigid main frame supports the front wheel, pedals, handlebars, and seat, and the rear frame supports the rear wheel. The rear frame includes a first pair of struts which are pivotally connected to the main frame at the lower rear portion thereof and a second pair of struts which are pivotally connected to the first pair of struts. When the rear frame is in the riding position, the first pair of struts extends rearwardly from the main frame, and the second pair of struts extends upwardly and forwardly from the rear ends of the struts of the first pair to a connector on the upper rear portion of the main frame which connects the second pair of struts to the rear of the main frame. When the bicycle is to be stored, the struts of the second pair are disconnected from the connector at the rear of the main frame, the two pairs of struts are pivoted forwardly about the pivot connection between the main frame and the first pair of struts, and the struts of the second pair are connected to a second connector on the upper front portion of the main frame.
