Abstract

La présente invention se rapporte à une bicyclette à direction par roue arrière dans laquelle une roue arrière tourne pour commander la direction d'avancement de la bicyclette. La présente invention se rapporte plus particulièrement à une bicyclette à direction par roue arrière dans laquelle des galets pivotants (230) de roue arrière sont conçus pour commander la direction de la roue arrière de façon à diriger la bicyclette, et espacés d'un arbre rotatif de roulement de sorte que les galets pivotants de roue arrière puissent tourner vers la gauche et vers la droite. La bicyclette à direction par roue arrière de la présente invention est entraînée par la propulsion obtenue par la rotation des galets pivotants (230) de roue arrière vers la gauche et vers la droite. La bicyclette à direction par roue arrière (1) de la présente invention comprend : un support de roue avant (100), à une première extrémité duquel une roue avant (110) est accouplée rotative et à l'autre extrémité duquel est accouplée une selle (120), une pédale (130) étant reliée à la roue avant (110) de manière à faire tourner la roue avant (110) ; et un support de roue arrière (200) comportant une partie raccord rotatif (210) formée au niveau d'une première extrémité de celui-ci et accouplée rotative au support de roue avant (100), des poignées gauche et droit (220) montées sur les surfaces latérales arrière de la partie raccord rotative (210), et une paire de galets pivotants (230) de roue arrière gauche et droit agencés à l'autre extrémité de celui-ci. Chacun des galets pivotants (230) de roue arrière comporte un rouleau (231), et les galets pivotants (230) de roue arrière peuvent tourner vers la gauche et vers la droite par la rotation des poignées (220).
