The best balance bikes can give a child a significant jump-start on their way to mastering cycling. As opposed to tricycles and training wheels that emphasize the pedaling action, a balance bike shows a child how to balance on two wheels while in motion.
Children come in all sizes, just like the bikes they use. There are bigger kids, smaller kids, kids who need more stability, and kids who need a strong frame. Ergo, the best kids bikes are really the bikes that best suit your kid, and your budget.
