Problems solved by technology

[0003] However, due to the use of the traditional chain transmission structure, the chain will often drop and unlink, especially the folding bicycles are mostly affected by the traditional chain transmission structure, so that the structure cannot be made very small
Despite the reduction in length, there is no reduction in volume, and it is still inconvenient to carry in terms of appearance and structure
Since the outline size is still large after folding, there are many parts and branches that are still not conducive to placement

The first drive device on the frame has input end fitting the pedal mechanism, and the foldable second drive device on the frame is connected to the back wheel and has input end capable of being fitted to the output end of the first drive device and output end fitted to the back wheel. The folding bicycle has no chain falling during folding and small size after being folded for easy carrying.

Description

【Technical field】 [0001] The invention relates to a foldable bicycle, in particular to a multifunctional miniature foldable bicycle. 【Background technique】 [0002] With the development of urban transportation modernization, modern transportation has become an indispensable and important part of people's life. But due to the shortage of energy, people are more and more beginning to favor the original means of transportation---bicycles. The main reason why people start to pay attention to bicycles is because the society advocates taking public transportation in order to save energy and reduce pollution. When people change to different means of transport or commute to and from get off work, bicycles play an irreplaceable role in other means of transport. In order to adapt to this need, various businesses have designed and produced various small bicycles and folding bicycles, so that people can carry them with them and use them. [0003] But owing to adopting traditional cha...
