Using the Topeak Child Seat is a breeze. First, attach the seat to the heavy - duty rack using the BabySeat™ attachment without any tools. Then, place your child in the seat and adjust the shoulder harness to a comfortable height. Make sure to secure the child's feet on the adjustable footrests. When cycling, the suspension system will absorb shocks, and the roll bar will protect your child's head. As for maintenance, regularly check the harness, footrests, and attachment points for any signs of wear. Clean the seat with a mild soap and water. When not in use, store it in a dry place. Always follow the safety standards and keep an eye on your child during the ride.
