Adams' Runner Bike is a great way for children to learn basic bicycling skills. It lets them easily put their feet flat on the ground for confidence. And, by pushing off, coasting and running, they quickly get a feel for balancing and steering. The long seat, quick-release seatpost and adjustable handlebars provide a great fit for children from two to five years old. Plus, this sturdy steel bike boasts tough nylon wheels with flat-proof tires for outstanding durability.
