Child trailers are specialized attachments designed to be pulled behind bicycles, allowing parents to transport their children safely while riding. These trailers typically feature a sturdy frame, weather-resistant cover, and safety harnesses to secure the child. They come in various sizes, accommodating one or two children, and often include storage space for gear. Many child trailers are equipped with features like adjustable seats, suspension systems for a smoother ride, and reflective materials for visibility. They provide a fun and safe way for families to enjoy outdoor activities together, promoting physical fitness and bonding time.
