Guide to Kid mountain Bike Sizes

Children's bike sizes are determined by wheel diameter, not seat height and frame size as is the case with adult bicycles. A critical factor is the brakes. Coaster brakes tend to be easier for young kids to use but they become less common as the bikes get bigger. After kids outgrow children's bikes they'll move into small-framed adult bikes with 26 inch, 27 inch or 700c wheels, which are sized by the length of the seat tube.
