While most other kids’ bike companies measure their bikes in terms of wheel size, Frog Bikes categorise their bikes according to the child’s inside leg measurement. A Frog 52, for example, is suitable for a child with a minimum inside leg measurement of 52cm. See below a guide to all frog bike sizes.

How to measure a child for a Frog Bike
Frog recommends following these steps:
- Stand your child with their back to the wall, wearing socks
- Place a book between their legs, as high as comfortable
- Get them to move away from the wall, and measure from the top edge of the book to the floor.
Example:
To get a certain size of Frog bike, your child should have a MINIMUM of the corresponding leg measurement. So if they have a leg measurement of 48cm or 51cm for example, a Frog 48 will be appropriate for them.
If their measurement is 46cm, a Frog 48 will be too big. They should opt for a Frog 43 (the next size down), which demands a minimum inside leg measurement of 43cm.
This is because a child with a leg measurement of 46cm will be able to ride a Frog 43 (43 cm) with the saddle higher up.
