Bike Size Chart for Kids

Kids Bike Size Guide Choose the right size kids bike.

As a child develops, so too does the kind of bicycle model and features that will best suit them. Below you will find a kid's bike size chart that highlights the best options for children according to their age group and their measured inseam.

One vital difference between size charts for children and adults is the fact that the former is measured using wheel size as a metric, whilst the latter uses frame size.
