Technical Field

[0001] The present invention relates to the technical field of bicycles, and more particularly to a front-end mechanism of a bicycle that can quickly position and assemble the handlebar stem group, the headset group, and the front fork group of the bicycle. Background Art

[0002] The assembly process of a bicycle is quite complex and requires the use of a variety of professional tools. For non-professionals or those who are not skilled, this can be a time-consuming and laborious process. In addition, the assembly process of traditional bicycles requires the use of various professional tools, and correct assembly of a bicycle also requires multiple complex adjustment steps.

[0003] During the assembly process of traditional bicycles, when assembling components with guiding functions such as the handlebar stem group, the headset group, and the front fork of the front-end mechanism of the bicycle, professional tools are required, and calibration and adjustment work are carried out after assembly. The reason is that if the front-end mechanism of the bicycle is not properly adjusted, its functions may not operate properly, posing a potential danger to the rider. Moreover, if the front-end components of the bicycle are not properly installed, excessive wear or malfunction may occur due to the inability of the components to cooperate with each other. Summary of the Invention
