Sunday Primer 18"BMX Bike
-
The Primer 18” is the ideal choice for riders who’ve outgrown a 16” but aren’t quite ready for a 20”. The shorter chain stay, lighter wheels and size-specific, pro-style frame geometry makes it the go- to bike for serious BMXers in this size range. The Primer is packed with quality parts like Odyssey Springfield Brakes and a fully sealed cassette hub for reliability that you can count on every time.

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. 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!
