Abstract

The invention discloses an adjustable portable bicycle. The adjustable portable bicycle comprises a main sprocket, a saddle, a front fork support for fixing a front wheel and a back fork support for fixing a back wheel; a central rotating shaft of the front fork support sleeves in a front fork shaft sleeve. The adjustable portable bicycle is characterized in that the bicycle is provided with a main shaft for connecting the front fork support with the back fork support; the main sprocket is arranged at the bottom of a sprocket supporting rod; the top and the bottom of the sprocket supporting rod are provided with sprocket supporting rod pipe clamps. The adjustable portable bicycle has the characteristics of portability, easiness for detachment, adjustability and the like. When the bicycle is used by different crowds, the sprocket supporting rod pipe clamps, a back fork pipe clamp and a saddle pipe clamp can be horizontally moved forwards or backwards along the direction of the main shaft by rotating adjusting bolts on clamp plates according to requirements of users, so as to shorten or lengthen distances between the main sprocket, the saddle, the front wheel and the back wheel; therefore the bicycle can provide convenience for different crowds.

Description

technical field [0001] The invention relates to a bicycle, in particular to an adjustable portable bicycle. Background technique [0002] In daily life, bicycle is widely used by various groups of people as an indispensable means of transportation in human life. But the main sprocket wheel of the bicycle sold on the market, the vehicle seat, the front and rear wheel distances are all fixed. Can not adjust the bicycle main sprocket, vehicle seat, front and rear wheelbase according to the rider's own characteristics when riding. And the above-mentioned bicycle cannot be disassembled smaller, so it is also inconvenient to carry. Contents of the invention [0003] The invention provides an adjustable portable bicycle to overcome the technical problems of the existing bicycles such as the inability to adjust the main sprocket wheel, the seat, the front and rear wheel distances, poor adaptability, and inconvenient carrying. [0004] In order to solve the above-mentioned techn...
