Rough Bike / Frame Size Guide

Which Size Bike Does My Child Require?
Children's bikes are generally measured by wheel size, rather than by frame size. Remember children do grow very quickly and you need to take this into consideration when buying a kids bike, However, if you buy a bike that is simply too big for your child, you will compromise your child's safety, and ultimately discourage your child from cycling.

3 to 5 Years 14 inches
