It is also possible to implement.

상기의 컨트롤러(28)는 구동모터의 회전수를 제어하여 자전거의 주행속도를 조절하는 것으로, 상기 케이스의 외측 접속단자를 통해 전방의 핸들에 부착된 엑슬레이터와 연결되어 있어서, 탑승자에 의해 주행속도가 조절된다. 상기 배터리(26)의 잔량을 확인할 수 있게 전원표시구 및 전원부 등을 포함한다.The controller 28 adjusts the driving speed of the bicycle by controlling the rotation speed of the driving motor. The controller 28 is connected to an accelerator which is attached to the front steering wheel through the outer connection terminal of the case, so that the traveling speed is carried by the occupant. Is adjusted. It includes a power indicator and a power unit so as to check the remaining amount of the battery 26.

이처럼 본 발명은 자전거에 전동수단을 장착하면 전기에너지에 의해 용이하게 주행할 수 있음은 물론, 배터리를 충전중에나 인력 주행시에는 전동수단을 분리하여 자전거의 중량을 감소시킬 수 있게 된다. 그리고 간단한 구조로서 내구성이 우수하며 남녀노소 누구나 용이하게 사용할 수 있어 매우 실용적이다.As such, the present invention can be easily driven by the electric energy when the electric means are mounted on the bicycle, and the weight of the bicycle can be reduced by separating the electric means while the battery is being charged or when the manpower is being driven. And it is very practical because it is simple in structure and excellent in durability.

아울러 본 발명에 따른 자전거의 탈착식 전동장치는 자전거(1)의 앞바퀴를 지지하는 프레임의 서스펜션부에 발전기(미도시)를 부착하면, 앞바퀴의 회전력에 의해 상기의 발전기가 작동하게 되고 발생한 전기에너지를 배터리(26)에 충전되도록 구성하는 것이 바람직하다. 예컨대 내리막 길이나 평지에서처럼 인력으로 다소 편안하게 주행할 때 발전기를 작동시켜 배터리가 충전되도록 한다.
In addition, the removable transmission device of the bicycle according to the present invention, if a generator (not shown) is attached to the suspension portion of the frame supporting the front wheel of the bicycle (1), the generator is operated by the rotational force of the front wheel and the generated electrical energy It is preferable to configure the battery 26 to be charged. For example, when driving downhill with some comfort, such as on a downhill road or on a flat surface, you can run the generator to charge the battery.
