Adjustable bicycle

Abstract

The invention relates to an adjustable bicycle comprising a bicycle transverse frame assembly, a front vertical rod assembly and a saddle vertical rod assembly. The bicycle transverse frame assembly is internally provided with a pneumatic supporting rod capable of adjusting the extending and contracting length of a bicycle body. Both the front vertical rod assembly and the saddle vertical rod assembly can rise and fall freely through a quickly-dismounted seat clamp, and thus the bicycle can be suitable for being ridden by people of various ages and heights, and in addition, the bicycle can becontracted to the minimum size to be placed in a car trunk so as to serve as a tool for riding instead of walk or a driving tool. The stroke between an inclined lump assembly and a limiting block is decreased when a first hanging-fastening screw of the front vertical rod assembly rotates in the clockwise direction, the inclined lump assembly is lifted up to be tightly supported through outer teethand the inner wall of a steering pipe so as to lock a front fork, and in this way, a first reset spring in the upper portion of a vertical rod outer pipe can achieve the damping function. A second hanging-fastening screw and an adjusting nut of the saddle vertical rod assembly are used for adjusting the spring stress stroke to be applicable to vehicle-mounted main bodies of different weights, anda second reset spring achieves the damping function.

Description

technical field [0001] The invention relates to a bicycle, in particular to a telescoping, adjustable and shock-absorbing small-diameter bicycle or an electric bicycle. Background technique [0002] At present, with the continuous development of social economy, people's awareness of environmental protection is getting stronger and stronger, so more and more people choose to ride bicycles when they go out, so smart bicycles are currently popular products, but there are no products on the market Grasp the most objective demand point in terms of function. The addition of some sports data and riding data monitoring to some products has indeed helped the product to some extent, but the most important riding experience of the bicycle has not been effectively improved. The seat post of the bicycle saddle only plays the effect of connecting and fastening the saddle functionally at present. However, when people are riding a bicycle, due to the different timing of pedaling on the le...

Problems solved by technology

Similarly, the design of the handlebar of a bicycle does not take into account the torsional movement produced by the human body during riding. Long-distance riding will make the rider feel tired and numb in the contact parts of the body and the bicycle.

[0003] In addition, although the current bicycle has an easy-to-carry folding bicycle design, it has never considered the rider's height and shape for the bicycle size adaptation requirements from the bicycle itself. People of different ages and heights need different sizes of bicycles. The best comfort can be obtained by adapting the bicycle, but the adaptability and economy of changing bicycles of different sizes are too poor
