Abstract

L'invention concerne une bicyclette à moteur à entraînement à pédale à mouvement alternatif, qui comporte un cadre, un mécanisme de freinage, une roue arrière motrice et un essieu de roue arrière, des pneus, des pédales qui sont fixées à des manivelles et des engrènements moteurs à secteur, des volants à action unique qui s'engrènent avec lesdits engrènements et qui ont des dents en prise. Chaque côté du cadre comporte une manivelle et sa pédale, un engrènement moteur à secteur et un volant à action unique. La pédale est reliée à l'extrémité avant de la manivelle, et l'engrènement moteur à secteur à l'extrémité arrière de ladite manivelle. Un orifice est percé à travers la manivelle entre les deux extrémités. Un tenon est relié au cadre. La manivelle est articulée au cadre par le biais de l'orifice et du tenon. L'engrènement moteur à secteur comporte un anneau denté intérieurement ou une structure de chaînes intérieurement en arceau. Le volant à action unique est doté de dents ou de chaînes dans la voie de roulement externe. La manivelle est reliée à la surface d'extrémité ou à la voie de roulement externe de l'engrènement moteur à secteur. Un crochet latéral est installé sur un côté de la pédale. L'objet de l'invention présente de nombreux avantages tels que sa simplicité, son aspect pratique, compact et confortable ; en outre son efficacité d'entraînement est élevée ; il présente également des fonctions anti-cliquetis et anti-explosion.
