The present invention relates to a dual battery pack apparatus for an electric bicycle, which mounts a first battery pack and a second battery pack on a frame of the electric bicycle, and when one of the two battery packs outputs a low-voltage signal, allows a user to convert and use the other, thereby increasing the driving distance of the electric bicycle and preventing an accident which may occur as a battery becomes discharged. More specifically, according to the present invention, the first battery pack is installed on the frame with a saddle, and the second battery pack is mounted on the frame connecting the saddle and a handle, thereby allowing a user to easily and conveniently charge, repair, replace, mount, separate, or use the saddle and any of the two battery packs. In addition, one side of the battery pack rotates on a place formed on the frame to put or take out the battery pack into or from the place such that power supply is connected by mounting the battery pack on the place so as to supply power and thus, a user can conveniently use the battery pack.

    전기 자전거의 프레임에 제1배터리 팩과 제2배터리 팩을 장착하고, 어느 하나가 저전압 신호가 출력하면 나머지 배터리 팩으로 전환하여 사용할 수 있게 구성하므로, 전기 자전거의 주행 거리를 늘리면서도 배터리가 방전함에 따라 발생할 수 있는 안전사고를 미리 방지할 수 있다. 특히, 제1배터리 팩을 안장을 장착한 프레임에 설치하고, 제2배터리 팩을 안정과 손잡이 사이를 연결하는 프레임에 장착하므로, 충전할 때나 수리나 교환 등을 할 때 쉽고 편리하게 장착하거나 분리하여 편리하게 사용할 수 있다. 또한, 배터리 팩의 한쪽을 프레임에 형성한 자리에 대고 회전시켜서 자리에 수납과 인출할 수 있게 구성하므로, 자리에 배터리 팩을 장착하면 전력을 공급할 수 있도록 전원연결이 이루어지게 하여 편리하게 사용할 수 있다.
