A heavy-duty high carbon steel frame is the backbone of this 16 inch kids bike, and the quick release lever makes handlebar and saddle adjustment fast and secure. The dual brake system combines a hand brake with a rear coaster brake, and two removable training wheels help children learn to ride and keep their balance. Shock absorbing, anti-puncture wheels stay steady on lawns, cement floors, boardwalks and asphalt roads, while anti-slip handlebars and pedals improve control. A fully enclosed chain guard covers the chain, tools are included for assembly, and the bike is ASTM compliant and CPSIA approved.
