The present invention relates to a bicycle frame which is manufactured in an injection molding method. The present invention exerts the following effects. That is, by a structure which can be easily injection-molded and assembled, an inner density is minimized so that a bicycle is ultra-lightened. In addition, a load is efficiently dispersed so that durability is very excellent. To this end, a left frame and a right frame are respectively injection-molded to be assembled. In an assembled state, a vacant space is formed, and a plurality of ribs protruding from an inner surface of the frame are formed.
본 발명은 사출성형 방식으로 제작되는 자전거 프레임에 관한 것이다. 본 발명은 다음과 같은 효과를 발휘한다. 즉, 사출성형 및 조립이 용이한 구조로써 내부 밀도를 최소화하여 자전거를 초경량화 하면서도 하중을 효율적으로 분산시켜 내구성이 매우 뛰어난 장점이 있다.
