La roue repliable selon la présente invention comprend : une pluralité de roues unitaires formées par division de la roue ; un arbre de support principal composé d'un arbre interne et d'un arbre externe et fixé au niveau de roues unitaires sélectionnées respectives, l'arbre de support principal modifiant la forme de raccordement des roues unitaires au moyen d'un réglage de la longueur de ce dernier ; des éléments de raccordement reliant entre elles les roues unitaires ; des arbres de support auxiliaires qui ont chacun une extrémité qui est articulée sur la surface interne de la roue unitaire et l'autre extrémité qui est articulée sur l'arbre externe, l'arbre de support auxiliaire ayant une longueur qui peut être ajustée pour supporter le poids de la roue circulaire ; un fil raccordé aux roues unitaires au moyen de l'arbre de support principal de sorte à être tiré pour combiner les roues unitaires et à conserver la forme de la roue circulaire lors de la rentrée de l'arbre de support principal ; et un élément de fonctionnement qui tourne pour tirer davantage le fil après la rentrée de l'arbre de support principal de sorte à limiter le positionnement des roues unitaires de telle sorte que les roues unitaires ne puissent pas être séparées.
