Sunday Primer 18" BMX Bike
Sunday Primer 18" BMX Bike
-
The Sunday Primer 18" is the next step for younger riders on their journey from a 16" to a full size 20" bike.
It's important that younger riders have access to not only an affordable and durable bike but one that lets them keep on progressing without being restricted.
Its shorter chain stay, lighter wheels and size-specific, pro-style frame geometry make the Primer 18 the go-to for serious BMXers in this size range. Not forgetting the quality parts used on this bike to make it more reliable, the Odyssey Springfield Brake, Sunday Cornerstone Grips and a fully sealed cassette hub to name a few.

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!
