Abstract

L'invention concerne une transmission (30) pour bicyclette à plusieurs vitesses, dans laquelle le changement de vitesse se fait par détection automatique du couple de puissance de sortie, conversion automatique du couple de puissance détecté en un déplacement de changement de vitesse et changement automatique de la vitesse de la transmission (30) sous l'effet dudit déplacement. Une transmission de puissance d'entraînement, destinée à une bicyclette (10) à plusieurs vitesses, comprend un élément de changement de vitesse (47, 49), un capteur (51) de couple de puissance de sortie et un convertisseur (1, 2, 3), qui transforme le couple de puissance de sortie en déplacement de changement de vitesse, dans lequel l'entrée du couple de puissance de sortie est couplée audit capteur (51) et qui comporte une sortie de déplacement de changement de vitesse. L'élément de changement de vitesse (47, 49) est couplé à la sortie de déplacement de changement de vitesse du convertisseur.
