The invention discloses a hub-free electric bicycle. The problems that an existing electric bicycle adopts a hub structure, foreign matter is twisted into the hub structure, use of the bicycle is affected, the hub structure collides with four limbs of a passenger, and potential safety hazards exist are solved. The bicycle comprises a frame, a front wheel and a rear wheel, the front wheel and the rear wheel are connected to the frame, the rear wheel is connected with the frame through a driving mechanism, each of the front wheel and the rear wheel comprises an inner ring and an outer ring which rotate relatively, the frame is fixed to the inner ring of the front wheel, a gear ring is fixed to one side of the outer ring of the rear wheel, the driving mechanism comprises a shell and a driving motor, and the shell is connected with the frame. The inner ring is fixed to the shell, and an output shaft of the driving motor is meshed with the gear ring through a gear. The hub-free wheel is achieved, the structural design is novel, and the modern sense is achieved. Manufacturing materials are reduced, the weight of the wheel is also reduced, and the situations that the electric bicycle cannot walk, passengers are injured and objects are damaged due to the fact that four limbs or foreign matters of the passengers are twisted into the wheel hubs are avoided.

    本发明公开了一种无轮毂电动自行车。解决现有电动自行车采用轮毂结构,存在绞入异物,影响自行车使用,以及会发生与乘客四肢发生碰撞,存在安全隐患的问题。自行车包括车架,连接在车架上的前轮和后轮,后轮通过驱动机构与车架连接,前轮和后轮均包括相对转动的内圈和外圈,车架与前轮内圈相固定,在后轮外圈一侧上固定有齿圈,驱动机构包括壳体和驱动电机,壳体与车架相连接,内圈与壳体相固定,驱动电机输出轴通过齿轮与齿圈相啮合。本发明实现了车轮无轮毂化,结构设计新颖,具有现代感。减少了制作材料,也减轻了车轮的重量,避免了乘客四肢或异物被绞入车轮轮毂,导致电动自行车无法行走,造成乘客受伤,物体损坏的情况。
