ABSTRACT:
A folding bicycle comprises a frame, a front wheel and handlebars at the front end of the frame, a chain-driven rear wheel at the rear end of the frame, and a saddle carried at an intermediate part of the frame. The frame comprises a base formed as generally-aligned end-to-end tie members pivotally connected at their adjacent ends to a bearing unit, an apex joint bracket which is connected to the remote ends of the tie members by pivotal front strut members and a rigid rear strut member, and a support member which extends from the bearing unit and through the apex joint bracket and carries said saddle. The frame is collapsible on raising the support member to move the bearing unit towards the apex joint bracket and so swing the front and rear wheels downwardly into positions alongside one another.
