AI Technical Summary

Problems solved by technology

China is a major producer of bicycles, with hundreds of millions of bicycles. It is known as the kingdom of bicycles, and the export volume is more than tens of millions, which is quite impressive. With the development of social urbanization, traditional big-wheel bicycles have become clumsy, with storage space and weight. Especially the inability to carry it brings a lot of inconvenience to people. Bicycles are a cheap means of transportation. In order to alleviate the excessive congestion of public transport vehicles and the pollution of the exhaust gas emitted by internal combustion engine vehicles to the environment, it has become a major public nuisance in major cities. Research and development Ultraminiature portable bicycle is to solve the above-mentioned difficult problem, one of important ways, Germany, Japan and Taiwan etc. have obtained certain achievements in relevant technology, but all do not have the recent development of breakthrough.

[0003] At present, several kinds of foldable bicycles have been put on the market at home and abroad. After folding, the minimum size length is 800mm, and the maximum length is greater than 1200mm. There are still some problems that are too large and inconvenient to carry, and then shrink down.
