Sized for riders 41.3 in to 51.2 in tall, this 16-in kids bike carries a 4 to 7 year old through the years when they outgrow a 14-in frame. The saddle climbs from 22 in to 26.5 in and the handlebar rises with it. The seat is rated 99 to 110 lb, so it stays firm under a heavier rider. Reflectors at the front and rear return headlight beams. Rubber tires layer an outer tread over cord ply and an inner tube, and the 23-lb carbon steel frame stays light enough to lift onto a rack.
