Abstract

L'invention concerne une bicyclette compacte, surbaissée, à conduite couchée, qui présente une configuration de cadre tubulaire courbée. Le cadre comprend un tube horizontal courbé qui présente une courte section avant s'étendant vers l'avant et le haut, à un angle relativement grand; et une longue section arrière droite s'étendant vers l'arrière et le haut, à un angle relativement petit. Un tube avant est fixé à l'extrémité avant du tube horizontal pour recevoir une fourche et un ensemble guidon porté par une roue avant. Un premier ensemble support tubulaire est fixé au tube avant et au tube horizontal pour recevoir un ensemble d'actionnement de la manivelle. Un second ensemble support tubulaire est fixé au premier ensemble support tubulaire et au tube horizontal pour être porté par une roue arrière. Le second ensemble support tubulaire comprend au moins un tube courbé présentant une configuration arquée. La configuration du cadre offre, de préférence, une position assise qui maintient l'usager dans un profil bas tout en facilitant la conduite de la bicyclette.
