The 2022 Sunday Primer BMX really has a bike at this entry to mid level tier down to a fine art.
4 different top tube lengths (each colour is a different length) mean that no matter your height, you can get rad.
The smallest 20" top tube length even comes with a front load stem to make it a better ride for a smaller/younger rider.
Sunday BMX bikes always utilise top quality parts to make their builds, the 2022 model Primer uses sealed bearings in all the main pressure areas of a BMX bike, as well as high quality, aftermarket Sunday and Odyssey parts.
