Abstract

La présente invention se rapporte à une bicyclette repliable. Un organe de maintien de la selle est solidaire du tube principal du cadre de la bicyclette, et adapté, lors du dépliage de la bicyclette, pour venir se placer sur une entretoise inférieure du cadre de la bicyclette afin de porter un tube de selle de la bicyclette, la résistance du cadre dans les sens longitudinal et dans le sens latéral étant ainsi améliorée, et un tirant pouvant ainsi être éliminé du cadre de la bicyclette. Par conséquent, le cadre repliable de la bicyclette peut être renforcé et simplifié. Selon l'invention, le tube principal du cadre est également pourvu d'une potence arrière solidaire dudit tube et reliée à pivotement à l'extrémité supérieure d'une fourche arrière du cadre et à l'extrémité inférieure du tube de selle. Grâce à cette structure, on peut appliquer au cadre de bicyclette soit une fourche traditionnelle sans le mécanisme amortisseur soit une fourche équipée d'un mécanisme amortisseur, ce qui permet d'améliorer la souplesse structurelle de la bicyclette.
