Without pedals or a chain, this 12 inch balance bike lets toddlers push, glide and learn to steer at their own pace. The magnesium alloy frame keeps total weight to about 8 pounds so children can pick the bike up themselves, and anti-puncture pneumatic rubber tires roll smoothly indoors and out. The seat height adjusts and locks in place to follow growth, the handlebar rotates a full 360 degrees for free steering, and anti-slip grips help small hands hold on. An ergonomic seat and a footrest add comfort, and the bike is 90 percent pre-assembled and ASTM and CPSIA compliant.
