<p>A bicycle (10) is constructed to facilitate selective configuration in a plurality of positions between a fully standing or safety bicycle configuration (Fig. 2), and a horizontal or recumbent position (Fig. 1). A rider may dismount, remove retaining pins (83), reconfigure the bicycle into a different position, replace the retaining pins, and resume riding. A pivotable pedal assembly (71) and a shiftable seat assembly (11) are used to facilitate the selective reconfiguration.</p> |
