Description

Technical Field

[0001] The utility model relates to the field of bicycle shock absorbers, in particular to a waterproof electric bicycle shock absorber. Background Technique

[0002] Electric bicycles play an important role in modern means of transportation because they are not only environmentally friendly but also provide a flexible way to travel in the city. However, riding comfort and safety have always been one of the most concerned issues for electric bicycle manufacturers and users. The function of the shock absorber is to buffer the impact caused by road unevenness and ensure the smoothness of riding.

[0003] When installing the existing bicycle shock absorbers, most of them are directly fixed to the vehicle through multiple bolts. Since the vehicle is often used in different environments, the bolts are prone to rust and damage, thus affecting the user's disassembly of the shock absorber; therefore, we propose a waterproof electric bicycle shock absorber to solve this problem.
