Description

Technical Field

[0001] The utility model relates to the technical field of electric bicycles, in particular to a handlebar mounting structure of an electric bicycle. Background Art

[0002] The stem mounting structure of an e-bike is a key component connecting the handlebars and front fork, significantly impacting riding control, stability, and safety. The handlebar clamp typically consists of a clamping block and bolts. The clamping block is typically made of metal and may have a rubber or plastic gasket on the surface to increase friction and prevent scratches on the handlebars. Bolts are used to tighten the clamping block, securing the handlebars securely to the stem. For example, some e-bikes use M6 handlebar clamping bolts. Tightening the bolts secures the clamping block to the handlebars, preventing them from shaking during riding.

[0003] However, the existing connection method generally requires the use of tools such as hexagonal wrenches for auxiliary disassembly during assembly and disassembly, and uses a large number of bolts, which makes assembly and disassembly more laborious. At the same time, the handlebars are fixed by clamping, which is prone to displacement under force, and resetting requires specific tools for disassembly, which is inconvenient to use.
