The core of the power assisting system of the electric bicycle is a motor, a control system and a battery. The control system and the battery of the existing electric bicycle are two independent units which are respectively arranged on the lower pipe, the battery is only used as a power supply unit, and the two units are required to be respectively fixed and connected in a beam mode during loading. Meanwhile, the control system is also required to be connected with peripheral electronic components through a wire harness, so that the whole assembly is complex, and the wire harness is difficult to simplify. Because the frame is different, causes control system mounted position and space difference, leads to down the many types of tubular appearance structure various, simultaneously because control system mounted position is comparatively hidden, hardly installs and dismantles, in case break down, often need demolish peripheral pencil totally, leads to the trouble maintenance very difficult.

In addition, the bottom of the lower pipe of the existing electric bicycle is generally provided with an independent wire cavity, and a wire harness connected with a bicycle tap needs to pass through the wire cavity of the lower pipe and be led out from the tail end when the bicycle is loaded, and finally is connected to a control system. Because the wire cavity length is longer, the wire harness is very time-consuming and labor-consuming when the wire cavity is penetrated into the wire harness and is loaded and maintained.

Because the battery technology and the control system technology belong to different fields, the battery as a whole is always limited to power supply of the whole vehicle. The battery is more upgraded and developed in terms of structure, material, capacity and the like, and the control system and the battery have different technical requirements, and meanwhile, the technology integration of multiple systems is involved, so that the control system applied to the field of electric power assisted vehicles and the battery integration product are in a blank state at present. Therefore, the integrated design of the battery and the control system reduces the part assembly of the electric bicycle, reduces the wiring harness of the whole bicycle, and effectively improves the production efficiency of the electric bicycle.
