Embodiment Construction

[0049] In order to solve the foregoing various problems, the present invention provides a thin motor for an electric bicycle. The thin motor is coupled to the wheel and has a main shaft whose axis is aligned with the wheel. For example, the axle center is set on the disc brake rotor fixed on the hub. The torque generated by the motor turns the wheels directly, without the need for a transmission. In this way, the thin motor does not take up extra space on the bike. Since the thin motor is not disposed in the hub, there is no need to remove and reinstall the spokes of the wheel from the hub. When the bicycle has a quick release device and disc brake rotor, the thin motor of the present invention can be quickly and conveniently installed on the bicycle to reduce the cost and time for assembly.

[0050] Figure 2a and Figure 2b A thin motor 50 of the present invention is depicted. Because the thin motor 50 has an axial flux, the thin motor 50 has a larger magnetic flux are...

Abstract

An electric bicycle includes a frame having at least one supporting member, at least one wheel having a shaft fixed to the supporting member and a hub rotatable about the shaft, and at least one slim motor having a rotor coupled to the hub and rotating about an axis aligned with the shaft, wherein the slim motor drives the hub to rotate about the shaft.

Description

technical field [0001] The invention relates to an electric bicycle, in particular to an electric bicycle actuated by a thin motor. Background technique [0002] For existing e-bikes retrofitted from traditional bikes, the motor is mounted inside the hub, usually the rear hub, to spin the wheel. However, the spokes of a conventional bicycle must be removed before the motor is mounted on the hub. Therefore, when the motor is reassembled, the spokes are also refastened one by one, which requires a lot of time for assembly. In addition, since the wheels of different brands of bicycles have different specifications, it is necessary to adjust the motor design for each different bicycle brand, thereby increasing the production cost. [0003] There is another existing electric bicycle structure, in which the motor is arranged on the frame of the bicycle, and a chain, a belt or a gear coupled to the motor are used to drive the wheels to rotate. Mounting the motor on the bicycle f...
