The feature of the kids bike

The chain cover of the children's bicycle is essential. The children's bicycle with the highest saddle height equal to or greater than 560mm shall be equipped with a disc chain cover or other protective devices to cover the outer surface of the meshing part on the chain and sprocket. When the chain is fully meshed on the sprocket, the disc chain cover shall exceed the outer side of the chain in the diameter direction, and other protective devices shall be used instead of the disc chain cover, The covering range shall be extended to at least 25mm along the chain from the point where the sprocket teeth initially enter the two sides of the chain. The children's bicycle with the highest height of saddle less than 560mm shall be equipped with a chain cover, which shall cover the outer surface and edge of the chain, sprocket and flywheel, as well as the inner surface of the sprocket and the meshing part of the chain and sprocket, so as to prevent children's fingers from being hurt. Because children's bicycles are not used for riding on the road, they must be used under the supervision of adults and must not be used on the road
