The present invention relates to a bicycle transmission using a variable speed motor and a planetary gear mechanism, including: a first input rotation shaft connected to a main power source to rotate; a second input rotation shaft received rotatory force from the variable speed motor; a planetary gear mechanism receiving rotatory force from the first input rotation shaft and the second input rotation shaft; an output shaft receiving rotatory force from the planetary gear mechanism; and a control unit controlling the variable speed motor to control a rotatory direction and speed of the second input rotatory shaft, wherein the first input rotatory shaft is provided concentrically with the output shaft, thereby simply miniaturizing the transmission and being capable of performing a multi-stage shift.

    본 발명은 변속모터와 유성기어 메카니즘을 이용한 자전거용 변속장치에 관한 것으로서, 특히 메인동력원에 연결되어 회전하는 제1입력회전축과; 변속모터로부터 회전력을 제공받는 제2입력회전축과; 상기 제1입력회전축 및 제2입력회전축으로부터 회전력을 제공받는 유성기어 메카니즘과; 상기 유성기어 메카니즘으로부터 회전력을 제공받는 출력축과; 상기 변속모터를 제어하여 제2입력회전축의 회전방향과 속도를 제어하는 제어부;를 포함하되, 상기 제1입력회전축은 상기 출력축과 동심원상에 배치되어, 변속장치를 단순 소형화하고 다단변속이 가능하도록 할 수 있는 효과가 있다.
