L'invention concerne un minivéhicule à pédalier comprenant un châssis, deux roues avant et deux roues arrière, un organe d'entraînement, un organe de rotation, un engrenage et un organe de freinage. L'invention est caractérisée en ce que l'organe d'entraînement renferme deux pignons de réduction dont la bague interne est reliée à l'arbre de commande ainsi que deux pédaliers, un à droite un à gauche, qui sont respectivement en prise avec les leviers fixés sur les bagues externes des deux pédaliers. L'invention tire profit de l'organe d'entraînement qui impartit un mouvement alternatif aux pédaliers, d'un volant qui dirige ce véhicule et d'un accélérateur. Les atouts sont : simplicité du véhicule, petite surface, multiples fonctions, facilité de pilotage, sécurité et adaptation au trafic urbain.
