Size guides

These size guides are intended to help you find the right size for the cycle clothing you want to order.
Most manufacturers use slightly different sizing so a medium jersey by one brand may be slightly different to a medium by another brand.

If you're in any doubt as to what size you need please don't hesitate to get in touch with our instore staff by calling us on 01663 735020 and we'll be happy to help you.

Frog Children's bike size guide:
In contrast to many kids' bikes, Frog bikes are sized by the leg length rather than age, as this is the most reliable way of getting the right size of bike for each child. Age alone isn’t a reliable measure as there is a large spread of “normal” leg lengths & heights for each age.

Please take the time to measure the rider’s inside leg. 
It’s easy to measure:

  1. Stand the child in socks against a wall 
  2. Place a small book between their legs, as high as is comfortable 
  3. Ask the child to move away and measure from the top of the book to the floor. 

Once you have measured the inside leg, use this table to find the right size of bike for your child. Note we give the MINIMUM inside leg length for each bike, with the saddle at its lowest setting. At this height, the child will safely and comfortably be able to get their feet on the ground. Don’t worry - Frog Bikes have long seat posts, so the saddle can be raised a long way as the rider grows.
