What Size Kid's Bike

Kids’ bike sizes are a lot easier than adult bikes. With adult bikes, it is the frame that is measured and this can be done in inches, centimetres or simply small, medium and large, depending on the brand. With kids bikes, everyone measures them using the size of the wheel. So, when you see a kids bike referred to as a 12” or 20” it is the wheel size they are talking about.

Before you buy it's important to check the sizing for individual bikes as they can vary from brand to brand. Even some bikes from the same brand will have different size ranges. The table below is a general guide to get you started:
