Abstract

The utility model provides a folding bicycle for leisure, which belongs to the technical field of a bicycle. The structure of the utility model is composed of bicycle handles, outer connecting pipes of the bicycle handles, a goods seat, two front wheels, single back wheel and connection controlling components between the front wheels and the back wheel. The telescoping, rotation and folding of the bicycle can be realized by structural components, such as quickly opening components. When the bicycle is used, the bicycle is returned to a natural state and the bicycle can be safely used at that time. When the bicycle is not used, the volume of the bicycle can be changed into a small volume as much as possible through the folding methods, such as retraction, rotation, etc., so as to achieve the aim of portability. Therefore, the technology has great popularizing and using value.

Description
