Kids Mountain Bike Size Guide

Welcome to the kids mountain bike sizing guide! This is where things start to become a little more specialist – so if your child is below the age of 5, we recommend looking at the “standard” kids bike sizing guide instead. We carefully select a small range of proper kids mountain bikes every year to ensure that it isn’t just the adults who have all the fun.

We have separate guides for men's mountain bike sizing and for women.

We hope the guide is helpful, and if you’d like to talk to one of our friendly team for advice then please don’t hesitate to contact us.
