Description

Technical Field

[0001] The utility model relates to the field of electric bicycles, in particular to a new type of two-wheel electric bicycle with a front bucket. Background Art

[0002] The front-bucket electric bicycle is a favorite means of transportation for Europeans. Children can be seated in the front bucket, or items can be placed in it. It is a green way to travel, convenient and practical. The biggest difference between the front-bucket electric bicycle and an ordinary bicycle is that the handlebar is not directly connected to the front wheel for steering. Instead, a front bucket is arranged between them. This requires a new steering mechanism to achieve the steering of the front-bucket electric bicycle.

[0003] Our company has newly designed a three-wheel front-bucket bicycle with a patent application number of 2024220320976. Since the three wheels take up a relatively large space, it is a bit inconvenient for people who like lightness, and some potential buyers may be lost.

[0004] On this basis, our company has newly designed a new type of two-wheel electric bicycle with a front bucket to overcome the above-mentioned defects. Make the products more refined and rich, and the commodities for consumers to choose from are more diverse, meeting the needs of different people. The richer the commodities, the more developed the economy, and the more prosperous the society. Content of the Utility Model
