How much clearance do you need for top tube?
Whatever the top-tube style, look for about 2″–4″ of clearance. Seat height: Most kids’ bikes are designed so they ride in a more upright position. They should be able to sit comfortably, see around them easily and grip the handlebars with a slight bend in their elbows.
Does effective top tube length matter?
The actual length of a sloping top tube will always be shorter than the corresponding horizontal distance. While effective top tube length provides a good idea of the overall length of the frame, it will be influenced by the angle of the seat tube, increasing as the angle gets slacker.
Is bike frame size top tube or seat tube?

Is reach or top tube length more important?
Reach is more constant. Consider a rider who is 6′ tall with two bikes; both bikes have a listed ETT of 610mm, but they have different seat angles. ETT is always measured in a parallel line to the ground starting at the top of the head tube.
How important is top tube length?
While effective top tube length provides a good idea of the overall length of the frame, it will be influenced by the angle of the seat tube, increasing as the angle gets slacker.
How important is head tube length?
Head tube length can give a general idea of how upright a bike is designed to be, but it is not the most important factor of fit since additional stack can be achieved with more steerer tube spacers or a taller stem. Head tube length is shorter on bikes designed to use with a suspension or suspension-corrected fork.
