Find the correct size in the table above:
Children’s bikes are sized by the diameter of the bikes’ wheels. Wheel sizes typically range from 12 inches up to 26 inches. While age can give a rough idea of what might fit, a child’s height (and even leg length) are far more reliable for choosing the correct size.
Parents are often tempted to size up in the hopes that their child will be able to ride their bike for longer, but children feel safer when their feet are able to touch the ground. That’s where a bike subscription is so helpful… there is no need to size up… you can simply choose a size that works for your child and swap it as and when they grow.
