New description: [New technical field] This creation is related to bicycles. In more detail, it is about bicycles whose frame can be geometrically changed to facilitate folding. [Prior Art] With the reduction of the global capital, 'energy conservation has reduced the pleadings of riding, so it has driven the market to demand no pollution or low pollution. In response to this-trend, the development of bicycle technology has also received much attention. In addition, there is a need for the use of bicycles and mass transit tools. In the various technical fields related to bicycles, how to facilitate the carrying and storage of bicycles is the most important issue. At present, there are various schemes for folding bicycles in the related technical field. However, in general, the design of the previous case focuses on the provision of a pivoting mechanism in the center of the frame, so that the frame is received in an axially folded manner. This design has a detrimental effect on the frame strength after assembly because it has to destroy the integrity of the frame spindle and thus poses a threat to the safety of the user riding. As far as the long-term use is concerned, it will also result in a shortened service life of the frame. It is obvious that the conventional folding scheme still needs to be improved by us. ® [New Content] In view of the lack of the folding bicycle in the previous case, the present invention provides a bicycle with a dynamic geometric frame system, which has a frame system that can be changed in geometric form, so that a user can easily assemble the bicycle. It can be used for riding or folding the bicycle for portable storage. In order to achieve the above objectives, the bicycle frame system with dynamic geometric frame system mainly includes a frame spindle, a rod and a movable link. The frame main shaft is detachably attached to the seat post, and the two ends of the movable link are respectively connected to the seat post and the main frame of the frame by rotating joints.
