Abstract

La présente invention concerne un dispositif de propulsion de bicyclette pour propulser des roues de bicyclette par la force des mains et des bras indépendamment de la force des pieds et des jambes, qui appuient sur les pédales. Le dispositif de propulsion de bicyclette de la présente invention comprend : un dispositif de levier ; une corde tirée par le dispositif de levier ; et une roue libre pour transmettre de l'énergie aux roues dans une seule direction de rotation en fonction de la traction de la corde, le dispositif de levier comportant un corps rotatif disposé de façon rotative au niveau d'une poignée de bicyclette et tirant la corde en fonction de la rotation, et/ou un levier d'actionnement de propulsion couplé par charnière à la poignée de bicyclette de façon à actionner celui-ci en tirant la corde. La présente invention peut obtenir une puissance pour propulser les roues de bicyclette par la force des mains et des bras séparément d'un processus de transmission de la puissance à une roue arrière par pédalage de la bicyclette avec les pieds et les jambes, de façon à surmonter la limitation de génération d'énergie additionnelle et augmenter l'efficacité de la propulsion par l'intermédiaire d'une structure simple.
