Abstract
A quick-mount crank-pedal mechanism for a children bicycle is provided. The quick-mount crank-pedal mechanism is composed of the following two parts including a crank rod and a crank bearing. The crank rod and the crank bearing are fitted with each other. With the mechanism, a pedal is enabled to be in a usable state quickly without using any tools, and a tip of the crank is effectively protected from puncturing through a carton, thereby reducing potential safety hazards.
