The present invention relates to a high-efficiency electric bicycle. In particular, in a high-efficiency electric bicycle using multiple driving motors, a plurality of driving motors are directly connected to a wheel to be mounted, such that an overload and heating of the driving motors may be reduced and the driving motors may be efficiently used. In addition, a plurality of driving gears which are rotated in accordance with the operation of the driving motors come in contact along the circumference of a differential gear mounted on a main shaft of the wheel, such that the rotation of the plurality of driving motors may be efficiently delivered to the wheel. Furthermore, a rotation blocking member is inserted between the driving gears and the driving motors to enable unidirectional rotation of the driving gears with respect to the driving motors. Therefore, a braking phenomenon in accordance with the rotation of the driving motors can be prevented on a downward slope, and electricity does not have to be supplied to the driving motors.

    본 발명은 고효율 전기바이크에 관한 것으로, 더욱 상세하게는 바퀴에 복수의 구동모터를 직접 연결하여 장착하도록 함으로써, 구동모터에 대한 부하 및 발열을 줄이고 효율적인 구동모터의 사용이 가능하도록 하며, 구동모터의 작동에 따라 회전하는 구동기어가 바퀴의 메인샤프트에 장착된 차동기어의 둘레를 따라 복수개 접촉되어 형성되도록 함으로써, 복수의 구동모터에 의한 회전이 바퀴에 효율적으로 전달되도록 하고, 구동기어와 구동모터의 사이에 구동모터에 대한 구동기어의 일 방향 회전만이 가능하도록 하는 회전차단부재가 삽입되도록 하여, 내리막길 등에서 구동모터의 회전에 따른 브레이킹 현상을 방지하고 구동모터에 전기의 공급이 필요없도록 하는 다수의 구동모터를 이용한 고효율 전기바이크에 관한 것이다.
