Using the Topeak Baby Seat II is easy. First, attach the heavy - duty disc mount rack to your 700c or 29A bike. You can do this without any tools thanks to the innovative BabySeat™ attachment. Then, place your baby in the seat and adjust the shoulder harness to the right height for a snug fit. Make sure the adjustable footrests and straps are set to keep your baby's feet away from the wheels. When you're done with the ride, you can quickly remove the seat from the rack without tools. Remember, the maximum weight capacity for the baby seat is 22 kg and 27 kg for the rack, so don't exceed these limits. Also, always check the seat and rack for any signs of wear before each use. To maintain the seat, clean it regularly with a mild soap and water. For the rack, wipe it down to prevent rust. Store the seat and rack in a dry place when not in use.
