Characteristics Of Children's Bicycle Products

The chain cover of children's bicycles is essential. Children's bicycles with a maximum saddle height of 560mm or more should be equipped with a disc chain cover or other protective devices to cover the outer surface of the meshing part of 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 the disc chain cover, 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. Children's bicycles with saddles with a maximum height of less than 560mm should be equipped with a chain cover that covers 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 children's fingers from getting hurt when inserted. Because children's bicycles are not intended for riding on highways, they must be used under adult supervision and must not be ridden on highways
