Abstract

L'invention concerne un véhicule à pédales à faible centre de gravité comprenant au moins une roue entraînée (44). Le véhicule comprend une structure (12), un premier et un second mécanisme d'entraînement (26, 34) fixés à la structure (12) et connectés par entraînement, et un mécanisme (52) de transfert d'entraînement connectant le second mécanisme d'entraînement (34) à au moins une roue entraînée (44) de façon à transmettre une force d'entraînement. Le premier et le second mécanisme d'entraînement sont pourvus de bras de manivelle (30, 32, 40, 42). Le véhicule comprend également une paire de plates-formes d'entraînement (54, 56), chacune d'elles étant connectée au premier et au second mécanisme d'entraînement (26, 34) de façon à obtenir un entraînement synchrone. Les plates-formes d'entraînement (54, 56) sont suffisamment grandes pour recevoir les pieds d'une personne et sont connectées à chacun des bras de manivelle (30, 32, 40, 42) du premier et du second mécanisme d'entraînement (26, 34) par l'intermédiaire de supports de montage (68, 77, 58, 67).
