According to the law of our country, students must be over 12 years old to ride bicycles on the road. Article 72 of the Regulations on the Implementation of Road Traffic Safety in People's Republic of China (PRC) stipulates that driving bicycles, tricycles, electric bicycles and motorized wheelchairs for the disabled on the road shall comply with the corresponding regulations, so driving bicycles and tricycles must be at least 12 years old.

However, for safety reasons, it needs to be decided according to the specific situation of children to ensure their own safety.
