Four wheel sizes share the same kids bicycle design, and this 16-inch version matches an adjustable handlebar with a 22.5-24-in saddle height so young riders can reach the pedals as they grow. The 44.5 x 21.5 x 30.5 in frame uses metal, rubber, PP, TRP and PVC components, and the seat is rated to 145 lbs to support kids within the 41.3-51.2 in height and 21.5-23.5 in inseam ranges. Dual hand and coaster brakes give children two ways to slow or stop, while crack-resistant, wear-resistant tires maintain contact with the ground. Two detachable training wheels help beginners keep balance, then can be removed as confidence improves. A front and rear reflector, bell and anti-slip pedals all contribute to a controlled, engaging ride for kids aged 4-7 years old.
