The 2022 Sunday Primer 20" BMX Bike might be sold as a beginner bike, but the componentry and geometry shows that it is much more. Sealed bearings in all of the important places, chromoly 3-piece cranks, and a list of Sunday and Odyssey components create a bike that has pro-level traits and geometry, but at a size specific for smaller riders. Utilizing a 20" toptube, BMXers 4' 10" - 5' 6" need not look further. Sunday has you covered with the 2021 Primer 20".
