Using this child bike seat is a breeze. First, find a bike with round or oval tube frames. Install the frame mount on the rear part of the bike following the simple instructions. Next, place your child in the seat and adjust the 5 - point harness system to fit them snugly, but make sure it's not too tight. Remember, the child should be at least 12 months old; if younger, check with a pediatrician. Also, the child must not exceed 40 lbs, regardless of age. When it comes to maintenance, the seat and harness padding are hand - washable and water - resistant. Simply take them off and give them a gentle wash. Store the seat in a dry place when not in use to keep it in good condition. This way, you can enjoy many bike rides with your little one for years to come.
