Technical Field

[0001] This utility model relates to the field of electric bicycle technology, specifically to an electric bicycle with an assembly spare box. Background Technology

[0002] With the popularization of the concept of environmentally friendly travel and the growth of short-distance transportation demand, electric bicycles have become an important means of transportation for urban and rural residents' daily commuting, shopping and outdoor leisure due to their advantages of convenience, economy and low energy consumption. In actual use, users often need to carry personal items, travel necessities, maintenance tools, etc., so the storage function of electric bicycles has become one of the key factors affecting the user experience.

[0003] The storage structures of existing electric bicycles mainly include three forms: front basket, rear spare box, and small storage box built into the body. However, the rear spare boxes of existing electric bicycles mostly use bolt rigid connection, which is inconvenient to assemble and disassemble, and has poor versatility.

[0004] Therefore, we provide an electric bicycle with an assembly spare box. Utility Model Content
