Abstract

The invention relates to transportation means, in particular to a shaft drive type foldable bicycle. The shaft drive type foldable bicycle aims to solve the problems that chain drive is adopted in most of existing foldable bicycles, only the middle portions of frames can be folded once, two wheels lose the rotating effect when combined together after folding and the bicycles are inconvenient to carry about and heavy. The shaft drive type foldable bicycle has the advantages that shaft drive decreases the failure rate of chain drive, and the rotating effect of the wheels is fully exerted by folding the bicycle twice; a user can pull the bicycle and will not feel that the bicycle is heavy when carrying the bicycle about, after being folded, the bicycle can be placed vertically and stably, only occupies a small space and can be conveniently taken into a public transportation means or a room, and the losing rate is effectively decreased; the bicycle has the functions of a luggage cart and a goods cart through slight change of the installation mode. The bicycle improves the use efficiency and brings convenience to green travel of people.

Description

technical field [0001] The invention relates to a vehicle, in particular to a shaft-driven foldable bicycle. Background technique [0002] Most of the existing folding bicycles are driven by chains, and can only be folded once in the middle of the vehicle frame; after folding, the two wheels are joined together, and the rotation function of the wheels is lost, so it is very inconvenient and heavy to carry. Contents of the invention [0003] The purpose of the present invention is to solve the problem that most of the existing folding bicycles are driven by chains and can only be folded once in the middle of the frame; after folding, the two wheels are joined together, and the rotation function of the wheels is lost, which is very inconvenient and heavy to carry around. The problem is to provide a shaft-driven foldable bicycle. The present invention includes a handlebar assembly 1, a rotating and fixing device 2, an outer circle and an inner square rotating tube 4, a front...
