Using the Dash RM MIK HD child bike seat is easy. First, attach it to your MIK HD rear bike rack without any tools. Place your child in the seat and adjust the 5 - Point harness to fit snugly but not too tight. Make sure the adjustable footrest is at a comfortable position for your child and fasten the safety strap. When it's time to clean, simply remove the seat pad and hand - wash it. As for maintenance, regularly check the MIK HD connection for any signs of wear and tear. Ensure the reflector is clean and visible. Remember, the weight limit is 40 lbs, so don't exceed this to keep your child safe.
