Detailed Description
The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
As shown in the figure, the motorcycle hub comprises a middle drum 1, spokes 2 and a rim 3, wherein the middle drum 1 and the rim 3 are concentrically arranged, 5 spokes 2 are connected between the middle drum 1 and the rim 3, each spoke 2 is obliquely arranged in the same direction, the oblique direction is opposite to the driving rotation direction of a wheel, the middle drum 1 is of a shell type structure, the middle of the middle drum is hollow, the spokes 2 are also of the shell type structure, the middle of the middle drum is hollow, the diameter of the middle drum 1 of a rear wheel is smaller than 125mm, when the middle drum is used as a front wheel, a brake connecting disc 4 is arranged on one side of the middle drum 1, six connecting supports which are uniformly distributed along the circumference are arranged on the brake connecting disc 4, and brake columns are respectively arranged on the connecting supports.
