AI Technical Summary
Replacing traditional bicycle spokes is complex and has limited shock resistance, making it impossible to replace them without disassembling the wheels, tires, and other components.
The spokes feature a twisted spoke assembly structure, with the spoke body composed of carbon fiber and aluminum alloy layers. Combined with multiple connecting blocks and threaded heads, this design achieves both detachability and connection stability of the spokes.
It improves the tensile strength and compressive strength of the spokes, enhances their aesthetics, and allows for quick and easy replacement when spokes are bent, deformed, or broken, while ensuring connection stability during use.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of bicycle spoke technology, specifically a twisted spoke assembly structure. Background Technology
[0002] Bicycle spokes are many rods, bars, or straight lines that extend outward from a central point or pivot on the same plane. They are the straight rods or steel bars that connect the hub and rim of the wheel. The tension, bending, deformation, or breakage of the bicycle spokes directly affect whether the bicycle wheel rotates on the same plane, and thus whether the bicycle can be ridden stably.
[0003] When bicycle spokes become bent, deformed, or broken, they need to be replaced promptly. Traditionally, because the spoke length and the distance between the rim and hub remain relatively constant, the spokes cannot be directly connected to the rim. Therefore, the wheel and tire must be disassembled before the spokes can be replaced, making the process complex. Furthermore, existing spokes are mostly vertical cylinders with limited tensile and shock resistance. Therefore, we propose a twisted spoke assembly structure. Utility Model Content
