The seat on this 16-in kids bike is rated to 145 lbs, well past what most kids bikes carry, which is why the frame survives being handed down from one sibling to the next. Heavy-duty high carbon steel takes the curb hops and dropped landings that come with learning. Riders 41.3 to 51.2 in tall sit in range with the saddle set anywhere from 21.5 to 25 in. Anti-slip grips and pedals hold on through a sweaty afternoon and shock-absorbing anti-puncture wheels keep the ride steady. A fully enclosed chain guard plus a handbrake and rear coaster brake handle the stops. ASTM compliant and CPSIA approved.
