  • The Fit Eighteen is the perfect bike for kids that aren't quite big enough for a 20" BMX but still want a high-quality bike! A chromoly top tube and downtube along with sealed rear cassette and chromoly cranks make this bike super tough but also lightweight for even more bike control.

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.

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.
