Children of different ages and heights need bicycles of different sizes. Generally speaking, the size of children's bicycles can be selected based on their height. When choosing, make sure that the child's feet are flat on the ground so that they can ride steadily. The safety of children's bicycles is crucial. When choosing, check whether the brake system is sensitive and reliable, and whether the chains and tires are intact and undamaged. In addition, some high-end children's bicycles are also equipped with anti fall designs, such as auxiliary wheels and anti slip pedals, to ensure the safety of children during riding.

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.
