Abstract

Bicyclette pliable servant également de chariot, pouvant être pliée en deux en un point de flexion (1) situé dans la partie centrale du cadre de la bicyclette, et pourvue de roues auxiliaires mobiles verticalement (5, 6), d'un mécanisme neutre servant à débrayer la force d'entraînement, et d'une unité de couplage reliant entre elles la roue avant et la roue arrière (2), (3). On appuie les roues auxiliaires sur le sol, et une unité d'entraînement est mise au point mort, la roue avant et la roue arrière étant reliées latéralement entre elles, afin de convertir la bicyclette en un chariot. Pour retransformer le chariot en une bicyclette, on exécute ces opérations dans un ordre inversé.
