What else should I consider?

Standover height and saddle height should also be factored into finding the right size bike for your child. This will ensure that your child can stand comfortably over the top tube (cross bar) of the bike and be able to touch the ground when seated on the bike allowing them to stop and start without toppling off.

Find the right bike

We recommend purchasing your Frog bike from your local Frog stockist, who will build the bike for you and ensure it fits your child properly.

Your local Frog Bikes stockist will have many of our bikes available for the rider to sit on in-store. You will get help and advice on sizing, and receive ongoing service, as well as support. Using our FrogFit App, stockists can recommend models based on arm length, inside leg measurement, and a rider's confidence level.
