[0008] In the above novel hub structure for electric vehicles and motorcycles, the mounting disc is provided with a fixed flange, and the fixed flange is fixedly welded to the mounting disc and the intermediate disc respectively.

[0009] In the above novel hub structure for electric vehicles and motorcycles, the intermediate disc is provided with a fixed flange, and the fixed flange is fixedly welded to the mounting disc.

[0010] In the above novel hub structure for electric vehicles and motorcycles, reinforcing ribs are extendedly arranged at the connection of the intermediate disc and the spokes.

[0011] In the above-mentioned novel hub structure for electric vehicles and motorcycles, the connecting end of the spoke and the rim is designed in a curved arc shape.

[0012] Adopting the above technical solutions, the present utility model has the following beneficial effects:

[0013] The present utility model changes the previous spoke design and adopts a redesigned intermediate hub frame. The intermediate hub frame consists of two parts: a spoke and an intermediate disc. Due to the design of the intermediate disc, the mounting disc can be connected and fixed to the intermediate disc in various ways and can be selected according to market needs, thus facilitating the overall production and processing of the hub.
