The purchase standard of the kids bike(2)

Drive chain or belt of the kids bike
The transmission chain or belt of a toy car should be protected so that it cannot be touched. If tools are not used, the protective cover should not be removed, such as the wheel disc and chain of a bicycle. Reporters often see children's bicycles that do not meet this requirement in some small commodity markets. Children are active and curious. Once they reach into the rotating wheel, the consequences are unimaginable.

Generally, when braking test is carried out, the moving distance of toys with braking device activated shall not be greater than 5cm; Riding toys of 30kg or more shall be equipped with brake locking device.（China kids bike)
