Abstract

La présente invention concerne une bicyclette pliante, et plus particulièrement une bicyclette pliante qui peut être facilement transportée grâce la réduction de la taille globale et du volume global de celle-ci, par la mise en œuvre d'une action de pliage simple et un aspect externe simple. La bicyclette pliante de l'invention comprend : un cadre de support qui est doté d'une roue avant tournante dirigée par l'utilisation de poignées sur un côté vers l'avant, et qui est doté d'une selle sur laquelle peut s'asseoir un utilisateur sur un côté dans une partie supérieure ; un cadre pliant qui est doté d'une roue arrière accouplée rotative à un côté, et qui est accouplé pliant, par le biais d'une partie charnière, au côté sur une partie inférieure du cadre de support ; et une partie charnière permettant d'accoupler le cadre de support et le cadre pliant tout en générant au même moment une force motrice pendant la rotation de pédales situées sur les deux côtés et, lorsque le cadre pliant est plié, le cadre pliant s'éloigne selon un intervalle prédéfini du cadre de support par l'action rotative de la partie charnière, ce qui aligne la roue avant et la roue arrière.
