Your child should have an inseam of 45 cm or more to adequately touch the ground with a slight bend in the knees for optimum sizing. Your child can learn to push, balance, and coast in the Non-Powered mode. Graduate them to the powered mode (the holy grail of fun) as they show proficient use and understanding of the brake and the ability to coast and brake while standing.
