Size Guide


Age Child Height (cm) Child Height (feet/inches) Recommended Bike Size
4 - 7 100 - 120 cm 3' 4" - 4' 0" 16 inch wheel
7 - 9 120 - 135 cm 4' 0" - 4' 5" 20 inch wheel
9 - 11 135 - 145 cm 4' 5" - 4' 9" 24 inch wheel


When shopping for a kid’s bike you will most commonly see the sizing in relation to the outside diameter of the wheel rim (in inches). Adult bike sizes are often referred to in terms of the frame size. This is because adult bikes get more specialised and need different wheels for different applications.
