Abstract

본 발명은 2인승 자전거에 관한 것으로서, 2인의 탑승자가 자전거의 전진방향을 향해 각각 앉도록 한 쌍의 안장을 메인 프레임에 배치하고, 뒷바퀴 축과 보조 페달에 의해 회전하는 보조 피동 스프로켓 사이에 뒷바퀴 축의 회전력이 보조 피동 스프로켓으로 전달되지 않도록 단속하는 일방향 클러치가 마련되어 있는 것을 특징으로 한다. 이에 의하여, 2인의 탑승자가 자전거의 전진방향을 향하며 자전거의 전후에 위치한 한 쌍의 안장에 각각 앉은 상태에서, 각각 페달의 구동을 독립적으로 자유롭게 제어할 수 있고, 자전거의 주행 중 페달을 놓치더라도 다칠 것을 우려해 양발을 벌릴 필요가 없고, 안전하게 탑승할 수 있다.
