Abstract

L'invention concerne une bicyclette ayant un cadre présentant une structure renforcée, la bicyclette comprenant : une roue avant (11), une roue arrière (12), un cadre (30), deux pédales (80), un mécanisme de frein (50), un amortisseur (40) et une partie de bicyclette avant (20). La partie de bicyclette avant (20) comprend un guidon supérieur (21), une fourche avant (22) reliée à une extrémité inférieure du guidon (21), et un tube de direction (23) recouvrant une extrémité supérieure de la fourche avant (22). Une partie inférieure de la fourche avant (22) est reliée à la roue avant (11). Le cadre (30) comprend un tube supérieur (31), un tube inférieur (32), un tube droit (33) et une fourche arrière (34). Une extrémité avant du tube supérieur (31) est reliée à une extrémité supérieure du tube de direction (23) et s'étend vers l'arrière depuis le tube de direction (23), et une extrémité arrière du tube supérieur (31) est reliée au tube droit (33). Le tube droit (33) présente une forme de "V" approximative, et une extrémité inférieure du tube droit (33) est reliée à la fourche arrière (34). La fourche arrière (34) s'étend vers l'arrière depuis l'extrémité inférieure du tube droit (33). Le tube inférieur (32) est situé en dessous du tube supérieur (31), et s'étend d'une position de courbure centrale du tube droit (33) à une extrémité inférieure du tube de direction (23), et relie le tube de direction (23) au tube droit (33). Deux côtés d'extrémités arrières de la fourche arrière (34) sont reliés à la roue arrière (12). Une partie renfoncée vers le bas en forme d'entonnoir (311) est formée à partir d'une partie centrale du tube supérieur (31). L'extrémité avant du tube supérieur (31) est pourvue d'une partie convexe supérieure (312). La partie convexe supérieure (312) s'étend vers l'arrière et se réduit progressivement en taille pour avoir une forme de barre allongée, et s'étend vers la partie renfoncée vers le bas (311), ce qui permet d'augmenter la résistance globale du cadre (30).
