What age is a balance bike for?

Most balance bikes target 18 months to 5 years. The smallest models (with minimum seat heights of roughly 11 inches) suit kids around 18-24 months, while 14-inch models like the Strider 14x are aimed at 3- to 6-year-olds. For 12-24 month olds, many parents start with a four-wheel pre-balance bike before moving to a true two-wheel balance bike.
