Measuring your child for a bike

Inside leg measurement is the key fact you need to know when buying a bike from our website. This will ensure you don’t put your child on a bike which is too big or too small.

Each bike has been measured by us and a range of inside leg measurements recorded on the website for every bike.  The range is shown for each bike on its product page.  You can also search for bikes by inside leg measurement using our advanced search tool.

To accurately measure your child’s inside leg, please follow the instructions below or watch the video.

1. Stand your child against a wall, with their back and heels right against the wall.
2. Ensure their feet are an adult hand’s width apart.
3. Put the spine of a book vertically against the wall and between their legs.
4. Push the book as high as is comfortable.
5. Hold the book against the wall and ask them to step away from the wall
6. Measure from the floor to the top of the book in centimetres.
7. Repeat steps 1-6 twice to ensure you are getting a consistent measurement.
