Great condition Norco girl's bike. If i measure the wheel, its 24" diameter. If i measure the tube from the center of the sprocket to the top of the tube to where the seat slides in its 13". I was confused on how you measure kid's bikes. No issues, just too small for our daughter. She outgrew it once she was over 5' I'd say. Firm on the price. It's a good bike, doesn't need anything.
