We love the idea of running bikes because they teach kids to balance their bikes without having to worry about the pedals and they can start early. You don't even need training wheels. As soon as a child can walk he can start using a running bike. For most people, the Strider is a good enough running bike, and we love them. But if you have deep pockets consider Mores Design's Petitpierre carbon fibre running bike. It has adjustable fit, ergonomic grips and brake levers, shock absorbing saddle, LED lights on the grips and saddle, and more. The bike is essentially designed with the child's safety and comfort in mind.
