Using the Ampd Bros Ace - X Kids Joey Seat is a breeze. First, attach the seat cushion to the frame of your ACE - X step - over model. Make sure it's clipped on securely. Then, mount the footrests to the bottle cage brackets. You can adjust them for the best fit for your child. Attach the handlebar extension to give your child something to hold onto. When using the seat, always check that all parts are tightly secured before each ride. Keep an eye on your child to ensure they're comfortable and safe. To maintain the seat, clean the cushion with a mild soap and water. Avoid using harsh chemicals that could damage the materials. Store the seat in a dry place when not in use to prevent rusting of the metal parts.
