Abstract

A folding bicycle has a frame (10) comprising a base (19) formed by tie members (20, 21) pivotally connected at their adjacent ends to a crank bracket and at their other ends to a head tube (36) and rear wheel mounting brackets (39) respectively, a joint bracket (25) which is pivotally connected to front strut members (26, 27) pivoted to the head tube (36) and which is fixed to a rigid rear strut member (28) and a support member (18) which extends from the crank bracket and through the joint bracket (25) and carries a saddle (17). The frame is foldable by raising the support member (18) to move the crank bracket towards the joint bracket and so swing the front and rear wheels downwardly into positions alongside one another, Figure 2e. The support member (18) is hinged so that the saddle (17) can be swung downwardly to lie adjacent the wheels in the folded state. Prior to folding the frame the front wheel assembly (11,37) is turned through 180 DEG and handlebars (12) are swung towards one another. The cycle may alternatively have three or four wheels. <IMAGE>
