Using the Burley Dash Rack Mount Child Seat is easy. First, find a rear bike rack with tubing between 10 - 16mm. Then, use the tool - free connection to clamp the seat onto the rack. When placing your child in the seat, adjust the 5 - point harness according to their size, making sure it's snug but not too tight. The maximum weight limit for the child is 40 lbs. For longer rides, your child can rest their arms on the arm rests and adjust the footrests to one of the four positions, then secure them with the security straps. The rear storage compartment is great for keeping small necessities. After each use, check the harness for any signs of wear and tear. If the seat or harness padding gets dirty, simply remove it and wash it. The seat padding is water - resistant, but try to avoid prolonged exposure to heavy rain. Remember, this seat meets ASTM & EN regulatory standards, so you can have peace of mind knowing it's safe for your child. Always use the safety strap for an extra layer of security.
