Wheel for foldable bicycle

Abstract

The invention relates to a foldable bicycle, in particular to a wheel for a foldable bicycle. The foldable bicycle comprises a foldable bicycle and a universal wheel and is characterized in that a telescopic rod, below which the universal wheel is arranged, is fixedly connected below a middle support of foldable bicycle. The outside diameter of the telescopic rod is smaller than the distance between two foot pedals. Upper sides of inner and outer sleeves of the telescopic rod are provided with through holes which have the same dimensions. The length of the telescopic rod is fixed by a positioning element. The upper side of the universal wheel is provided with a brake device of which the diameter is equal to the outside diameter of the telescopic rod. The sum of the diameter of the universal wheel and the length of the telescopic rod is less than the radius of a rear wheel of the bicycle. The outside diameter of the positioning element is matched with the inside diameter of the through. The invention is simple in structure, low in manufacture cost and convenient in use.

Description

technical field [0001] The invention relates to a foldable bicycle, in particular to a wheel for the foldable bicycle. Background technique [0002] In the prior art, after the foldable bicycle is folded in half, the front wheel and the rear wheel are in the same orientation, and the center of gravity is between the person and the bicycle, which makes it difficult to walk, especially when entering the subway. You can still keep walking while walking for a short distance, but it is too tiring to carry it for a long distance, and it is difficult to control when dragging. Contents of the invention [0003] In order to overcome the defects in the prior art, the present invention provides a folding bicycle that can not only fix the center of gravity when it is dragged, but also brake the universal wheels when it is not dragged. Wheels for folding bicycles. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] A wheel fo...
