Abstract: A quick-mount crank-pedal mechanism for a children bicycle is provided. The quick-mount crank-pedal mechanism is composed of a crank rod, a crank bearing and a pedal. The crank rod and the crank bearing are fitted with each other, and the pedal is coupled to the crank bearing. With the mechanism, the 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.
