Abstract

La présente invention concerne un cyclo-pousse apte à tourner de manière flexible au moyen d'un décalage de centre de gravité, comprenant un corps de cadre (1). Une roue avant (2) est reliée à une extrémité avant du corps de cadre (1). La roue avant (2) est reliée aux pédales (4) au moyen d'un mécanisme de transmission (5), et se déplace vers l'avant sous la force d'action des pédales (4). Un ensemble roue arrière (3) est relié mobile à une extrémité arrière du corps de cadre (1). L'ensemble roue arrière (3) est entraîné, lorsque la force d'action change, de façon à osciller d'un côté à l'autre de manière à tourner. En modifiant la structure du cyclo-pousse, le cyclo-pousse peut tourner de manière flexible au moyen d'un décalage de centre de gravité.
