Description

Technical Field

[0001] This utility model relates to the field of bicycle frame technology, and in particular to a power-assisted bicycle frame with an anti-collision structure. Background Technology

[0002] Electric bicycles have a long history of use as a common tool for commuting and short-distance travel, and are widely used in urban roads, rural paths and other scenarios.

[0003] The current bicycle frame has the following defects: First, the fork tube is prone to deformation when it is hit from the side. Due to the lack of a special protective structure for collision scenarios, it cannot effectively resist the damage to the fork tube caused by side impacts. Second, the connection of various components of the frame is not stable enough. After being hit by a collision, it is easy to loosen, which will affect the overall structural stability and pose a hidden danger to riding safety. Utility Model Content
