Abstract

L'invention concerne un système de propulsion à assistance proportionnelle comprenant un extensomètre destiné à détecter et mesurer la flexion du moyeu de la roue arrière d'une bicyclette, cet extensomètre étant disposé sur une surface verticale dudit moyeu, une unité d'amplification servant à amplifier un signal de mesure provenant de l'extensomètre, un filtre situé à l'entrée de cette unité d'amplification, un convertisseur analogique-numérique installé à la sortie de ladite unité d'amplification, ainsi qu'un circuit de traitement numérique permettant de numériser le signal au niveau de la sortie de l'unité d'amplification de manière à compenser toute déviation dudit signal et à calculer, en temps réel, l'effort produit par le cycliste sur les pignons dudit moyeu, ce qui permet de réguler l'effort d'assistance du moteur c.c. sur le moyeu de la roue arrière de la bicyclette en vue de fournir une assistance progressive au cycliste.
