Children's bicycles are not considered a means of transportation for cycling on highways, therefore they must be used under adult supervision. In addition, when choosing and using children's bicycles, parents also need to pay attention to checking the quality and safety of key components, such as brakes, tires, screws, etc., and repairing or replacing problematic parts in a timely manner.

Children's bicycles are designed and manufactured with great emphasis on safety. For example, a chain guard is an essential component to prevent children's fingers from reaching between the chain and sprocket, causing injury. In addition, children's bicycles also need to comply with relevant safety standards, such as the National Toy Safety Technical Specification, to ensure the safety of children while riding.

There are two options for children's bicycles: rubber inflatable tires and rubber solid tires. Rubber inflatable tires have the characteristics of good elasticity, high comfort, and superior shock absorption performance, while rubber solid tires have the characteristics of explosion-proof, non inflation, and durability. There are mainly two types of braking methods: V-brake and disc brake, and the choice can be determined based on the child's age and riding habits.

Children's bicycles are usually made of materials such as high carbon steel, aluminum alloy, or carbon fiber, which have the characteristics of high strength, corrosion resistance, and lightweight, making them very suitable for children's cycling. At the same time, the design of children's bicycles also emphasizes safety, such as being equipped with protective wheels (balance wheels) to help children maintain balance, as well as a frame and seat design that conforms to children's ergonomics.
