portable bicycle

Abstract

The invention relates to a portable bicycle of which a steering handle is folded to be one half so as to be convenient for transportation and storage and the front wheel is enabled to be moved to the rear wheel so as to enable the length of the bicycle to be minimized. The portable bicycle provided by the invention comprises a main frame (1), a horizontal rack (2), and a handle (3), wherein a slide block (5) and a saddle (7) are coupled with the upper part of the main frame (1), a rear wheel (10) is coupled with the rear end of the lower part of the main frame (1), and a pedal crank arm (8) and drive parts (B1 and B2) are mounted at the front end of the lower part of the main frame (1); the horizontal rack (2) is coupled with the main frame (1) and slides in the forward and rearward direction, the length of the horizontal rack (1) can be adjusted through a length adjusting device (6), and the horizontal rack (2) is fixed on the front fork (12) of a front wheel (11); and the handle (3) is mounted at the upper end of the front fork (12) of the front wheel (11), comprises first and second bicycle handlebars (31 and 32), and is provided with a folding device (4) capable of folding or unfolding the first and the second bicycle handlebars (31 and 32).

Description

technical field [0001] The present invention relates to a portable bicycle, and more particularly, to a portable bicycle that can fold a steering handle in half and move a front wheel to a rear wheel to minimize the length so that the bicycle can be easily carried or stored. Background technique [0002] Generally, in modern life, a bicycle not only plays a role as a healthy exercise equipment, but also is a very useful tool as a means of short-distance mobility. However, due to the current road conditions, it is common to move to a bicycle lane where bicycles can be safely ridden or to ride a bicycle in a park in order to ride a bicycle. [0003] However, in order to ride a bicycle, the bicycle must be carried in the compartment of a car or moved by public transportation, which is not realistic. [0004] Therefore, by folding the bicycle, the volume is reduced and the bicycle is installed in a compartment, or a bicycle with a reduced volume is manufactured by shrinking the...

Problems solved by technology

[0005] In this way, in the case of only reducing the wheel diameter or reducing the size of the body, even if the protruding object is very small while the bicycle is running, the rider will receive a large impact, the moving speed is slow, and it is inconvenient to drive due to the small size

[0006] Also, a folding bicycle that folds the length of the bicycle in half by installing hinge pins is very bulky after being folded in half, and cannot be moved by rolling the wheels of the bicycle, so it is inconvenient to lift and move when moving.

[0007] Therefore, there is a problem that the bicycle cannot be easily moved by public transportation
