The invention discloses a carbon fiber bicycle, and belongs to the field of carbon fiber bicycle structures, the carbon fiber bicycle comprises a frame, the frame comprises a front tube, an upper tube, a sleeve and a lower tube which are connected in sequence; the bottom of the front pipe is provided with a front fork, and the rear part of the sleeve is provided with a rear fork; the front fork comprises two front fork pipes, and the rear fork comprises two upper fork pipes and two lower fork pipes; the bottom of the seat tube column is positioned in the sleeve; a carbon plate is arranged at one end of the metal barrel shaft, and the surface of the carbon plate is flush with the surfaces of the front fork pipe and the lower fork pipe respectively; one end of the brake cable and one end of the speed change cable penetrate out of the interior of the vehicle head, and the other end of the brake cable penetrates out of the interior of the vehicle frame. According to the carbon fiber bicycle disclosed by the invention, one end of the metal barrel shaft is hidden in the lower fork pipe, and the end part is sealed through the carbon plate, so that the situation that scratches are generated between the metal barrel shaft and the surface of the carbon fiber bicycle frame, and the flatness and attractiveness of the surface of the carbon fiber bicycle frame are affected is avoided.

    本发明公开了一种碳纤维自行车,属于碳纤维自行车结构领域,包括车架,车架包括依次连接的前管、上管、套管以及下管;前管上部安装车头,前管底部安装前叉,套管后部安装后叉;前叉包括两根前叉管,后叉包括两根上叉管和两根下叉管;还包括座管柱,座管柱的底部位于套管内;还包括金属筒轴,金属筒轴的一端设置碳片,碳片表面分别与前叉管和下叉管的表面平齐;还包括刹车装置、变速线与刹车线,刹车线与变速线的一端经由车头内部穿出,刹车线的另一端经过车架内部后穿出。本发明公开的碳纤维自行车,将金属筒轴的一端隐藏于下叉管内,端部通过碳片进行封闭,避免金属筒轴与碳纤维车架表面之间产生划痕,影响碳纤维车架表面平整美观。
