ABSTRACT:
A bicycle frame has front and rear frame portions interconnected at their top by a flexible spring connection, that allows relative vertical flexing of the frame portions, and by a tension cable and compression spring between a forward portion of the front frame portion and a lower portion of the rear frame portion. Integral stiffening means included with the vertical center post member of the rear frame portion and with the horizontal crossbar assembly of the front frame portion are provided to minimize the tendency of the front portion of the frame to yaw laterally from side to side relative to the rear frame.
