Abstract

Provided is a conventional riding and inclined-laying dual-purpose bicycle. On the basis of a conventional bicycle, the bicycle provided arranges an adjusting disc at the lower end of the vertical rod of a bicycle handle to enable the bicycle handle to rotate back and forth in the vertical surface by taking the adjusting disc as a circle center, the lower end of a seat rod is provided with a rotatable fulcrum to enable the seat rod to rotate back and forth by taking the fulcrum at a circle center; moreover, the middle lower part of the seat rod is provided with a bar-shaped hole to allow the seat rod to be fixed on a bicycle frame; the support rod of a carriage is telescopic so that the carriage can rotate by taking a front end fulcrum at a circle center, and the rear end of the carriage is provided with a small backrest which is capable of standing upright and leaning backwards. Accordingly, a conventional bicycle can be easily converted into an inclined-laying one, and riding in the inclined-laying manner exerts the strength of legs and reduces the pressure at buttocks and lumbar diseases.

Description

Tradition is ridden and is reclined and ride dual-purpose bicycle

Technical field

The utility model relates to a kind of dual-purpose bicycle that utilizes mechanics and body-care to learn, and especially two kinds of functions can be changed easily.

Background technology

At present, known when riding ordinary bicycle, the maximum of shank firmly will be subjected to the restriction of self body weight; Vehicle seat bears most of gravity of health, and is of long duration, can make people's buttocks and the small of the back uncomfortable.

Summary of the invention

The deficiency that exists in order to overcome ordinary bicycle, the utility model provide a kind of tradition to ride and recline and ride dual-purpose bicycle, and better usefulness is more comfortable.

The technical scheme that its technical matters that solves the utility model adopts is: establish rotatable and can a fix adjustment disk in handlebar montant lower end, make the handlebar can be upright, also can swing back; The fulcrum of seat rod lower end is arranged to S. A., and vehicle seat can rotate take fulcrum as the center of circle, can be upright, can swing back, and vehicle frame can be fixed in the middle and lower part of seat rod; The front end of shelf arranges S. A., and shelf can rotate as the center of circle take front end, and the strut bar of shelf is scalable, and the little backrest of shelf rear end is arranged to the device that can uprightly can swing back.

The beneficial effects of the utility model are, allow people can select different by bike modes, and are easy and simple to handle, practical healthy.
