Abstract

The invention provides a bicycle wheel. A locating body, an inner gear ring, a driving gear and the like are added to a hub of a driving wheel of a bicycle, and great difference exists between the driving method of the bicycle and an existing transmission method. According to the existing driving method, a chain only drives a fly wheel and the wheels to rotate to enable the bicycle to advance, after the parts are arranged, except that the chain drives a chain wheel namely the fly wheel and the wheels rotate to enable the bicycle to advance, forward inclining force is produced by the wheels, and a labor-saving effect is achieved.

Description

technical field [0001] The invention relates to a bicycle wheel, which is more suitable for bicycle wheels, and its structure is also suitable for motorcycle wheels, electric wheels and the like. Background technique [0002] Bicycles are the most economical, most environmentally friendly and lightest means of transportation, but riding for a long time will make people feel strenuous. New ways to save effort on your bike. Contents of the invention [0003] The solution of the present invention is a bicycle wheel, which is characterized in that: a bearing is installed in the hub, a positioning body is installed in the bearing, and the positioning body is cylindrical and can be hollow. The positioning body middle part is equipped with axle shaft, and bearing is arranged between positioning body and axle shaft, also can have no bearing, but will rotate flexibly. The axial centerline of the positioning body coincides with or is parallel to the axial centerline of the axle. ...
