The present invention relates to a structure and a function of a front wheel of a bicycle. An objective of the present invention is to resolve a tilt of a conventional bicycle to a side when moving the bicycle on the ground as the bicycle only has one front wheel. The present invention installs two supports on which auxiliary wheels are mounted to rotate on a left and a right of the front wheel of the bicycle. When the front wheel is folded to a rear, the auxiliary wheels contact the ground to make a three-wheel bicycle to prevent falling, and a user is able to stand in front of the bicycle and push the bicycle in an opposite direction to move the bicycle in a proper posture. According to the present invention, the two auxiliary wheels of the bicycle stably support the bicycle to allow the user to conveniently move the bicycle on the ground in a proper posture. When the front wheel is folded, a length of the bicycle becomes shorter to facilitate transport and storage; thereby not requiring an additional folding device to be installed.

    1. 기술분야 자전거 앞바퀴의 구조와 기능 2. 해결하려는 과제 일반적인 자전거의 앞바퀴는 하나로 구성되어 자전거를 견인할 때 옆으로 기울어져 매우 불편함. 3. 과제의 해결 수단 본 발명은 자전거 앞바퀴 좌우에 회전되는 보조바퀴를 장착한 2개의 지지대를 설치하고 본 바퀴를 뒤로 접으면 보조바퀴가 지면에 닿아 3륜 자전거가 되어 넘어지지 않으며 자전거 앞에 서서 반대로 밀면 바른자세로 자전거를 견인할 수 있다. 4. 효과 본 발명의 자전거는 견인할 때 2개의 보조바퀴가 자전거를 안정적으로 받쳐주어 바른자세로 편안하게 자전거를 견인하며 앞바퀴를 접으면 자전거의 길이가 짧아져 운송이나 보관이 용이하여 별도의 접는 장치를 설치할 필요가 없는 양방향 자전거.
