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. We have also simplified for you into XS, Small, Medium, etc.

Here is a guide to what size you should be looking for - note that there is some overlap in sizes, as personal preference also comes into the equation!
Rider Height (in) Rider Height (cm ) Wheel Size (in)  Top Tube Length (in) 
2FT - 3FT 60 - 90cm 12" 11.5" - 13"

    Back in the saddle thanks to Source BMX

    It's been a very, very long time since I've been on a BMX bike. While taking my nephew to the track to ride the bike I bought him, I got the itch to join him. I looked everywhere local and online and discovered Source BMX. I found this great bike and I'm looking forward to my nephews next visit👍

    Fantastic Trail Bike

    The milder head tube angle and extended chainstay give this bike a very mellow, controlled feeling on dirt roads. The frame is lighter than high ten steel, but not as light as full chromoly.
