[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on June 30, 2023, with application number 2023107986699 and invention name "Drainage Type Vehicle Pipe and Electric Bicycle", the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of electric bicycles, and more specifically, to a drainage-type vehicle pipe and an electric bicycle. Background Art

[0004] Traditionally, electric bicycles have been equipped with an electric motor as an auxiliary power source, significantly simplifying the mechanical components while improving the motor's transport capacity. However, existing electric bicycles have batteries built into the frame, which often have several openings in the tubes. Riders inevitably encounter rain or other inclement weather, and if rainwater or washing fluid enters the tubes during riding, they can be unable to drain out, potentially causing irreversible damage to the battery.

[0005] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present application, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.
