Sunday Primer Park BMX Bike (20.5" Toptube) - 2021

Sunday Primer Park BMX Bike (20.5" Toptube)
This item is currently not available.


Color scheme? Check. Bar spins for days? Check. The 2021 Sunday Primer Park BMX Bike is set from the very start. Sunday kitted it with an Odyssey Gyro and brake system meaning that you don't have to worry about your brake cable binding up during bar spins or tail whips. Sealed bearings in high stress areas and chromoly cranks contribute to the strength and durability needed for a rider learning new tricks. The Sunday Primer Park is hard to look past for the amazing parts and great price.
