Abstract: The present invention relates to a movable and height-extensible automated bicycle storage facility of which the height is simply increased by separately manufacturing a section exceeding a height limit under the Road Traffic Act, transporting and assembling the section at a desired place to use the automated bicycle storage facility manufactured in a container shape at the place. The present invention is characterized by ensuring a sufficient height by coupling a height extension cover to the top of the bicycle deck to prevent a bicycle from hitting against the top of the bicycle deck when the bicycle is loaded at an angle in the bicycle deck in the front-rear direction and then lifted and loaded onto the second floor, and by temporarily reducing the height by separating the height extension cover in order not to violate the Road Traffic Act when moving the bicycle deck to another place.
