The 2021 Sunday Primer 20" BMX Bike may be pitched as a beginner bike, but it is nothing to sleep on. Sealed bearings where you want them, 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".
