Abstract
A folding bicycle with a hinged frame comprising a front portion and a rear portion. The front and rear frame portions are connected by a hinge structure which permits the front frame portion to be rotated about the vertical axis of the hinge structure to a position against the rear frame portion for easy carrying or for insertion into a carrying bag. The folding bicycle is provided with a folding handlebar assembly which can be quickly adjusted from a standard ten speed driving configuration to a more relaxed touring handlebar configuration, or to a fully collapsed compact carrying position. The folding bicycle is provided with an adjustable soft ride seat, and with pedals which are reversible to reduce the overall width of the collapsed bicycle.
