Problems solved by technology

[0002] At present, although electric bicycles at home and abroad are pursuing miniaturization, the traditional frame and electric hub manufacturing technology limits the development of miniaturization. The motor and battery are reduced to the limit, and the body is still large and heavy, which is difficult to carry around.

Description

Technical field [0001] The invention relates to a miniature electric bicycle that can be folded and carried in a backpack. Background technique [0002] At present, although electric bicycles at home and abroad are pursuing miniaturization, the traditional frame and electric hub manufacturing technology has limited the development of miniaturization. The motor and battery have been reduced to the limit, and the body is still large and cumbersome, making it difficult to carry around. Contents of the invention [0003] In order to overcome the shortcomings of the existing electric bicycles that are bulky and bulky, the present invention provides a portable mini electric bicycle, which uses innovative frame and electric hub technology, is compact in folding, light and energy-saving, and can be carried in a backpack or a suitcase. [0004] The technical solution adopted by the present invention to solve its technical problems is: the portable mini electric bicycle is composed ...
