BMX BIKE SIZE GUIDE
BMX bikes are measured in two ways, the size of the wheel (20” is the standard BMX Wheel size) and the length of the frame which is gauged by the top tube measurement which we have also simplified for you into XS, Small, Medium etc categories.
Below is a guide to what size you should be looking for. note there is some overlap in sizes as personal preference also comes into the equation.
