The chain cover of childrens bicycles is essential. Childrens bicycles with a saddle height equal to or greater than 560mm should be equipped with a disc chain cover or other protective devices to cover the outer surface of the meshing parts on the chain and sprocket. When the chain is fully engaged on the sprocket, the disc chain cover should extend beyond the outer side of the chain in the diameter direction, and other protective devices should be used instead of disc chain covers, The covering range should be extended to at least 25mm along the chain from the point where the sprocket teeth initially enter the two sides of the chain. A childrens bicycle with a saddle height lower than 560mm should be equipped with a chain cover, which should cover the outer surface and edges of the chain, sprocket, and flywheel, as well as the inner surface of the sprocket and the engagement between the chain and sprocket, to prevent childrens fingers from getting hurt when inserted into it. Because childrens bicycles are not intended for riding on the road, they must be used under adult supervision and must not be ridden on the road.
