The 2021 Sunday Primer BMX Bike is ready to tear up your favorite riding spots. Designed to be an entry level bike, Sunday made sure to kit this model out to be able to withstand hard hits and abusive new tricks. Sealed bearings in high stress areas and chromoly cranks contribute to the strength and durability needed for a rider learning new tricks, and the lineup of Odyssey and Sunday parts add to the overall pro-level feel of the bike. The Sunday Primer Park is hard to look past for the amazing parts and great price.

Sunday 2021 Primer BMX Bike (21" Toptube) (Matte Army Green)
I bought this bike for my 14 yr old grandson. He loves everything about this bike. He was helping me winterizing my yard when we had to evacuate from wildland fire in Southern Oregon. He left his bike, gloves, helmet in my garage.
I believed we would be back & all ok. No the worst happened burnt my house, my car everything to the ground. I'm very happy with your quick response to deliver bike from my order date. Received gloves too. Waiting for backorder on helmet. He has been very excited & happy to receive his bike. Thankful I could get him his bike.

Came in an undamaged box so started out positive. Assembly was easy for a novice handyman with a selection of tools. Bought this for my 6’ son for Christmas. It seems sturdy and well built but will see once he rides it. I am pleased with the quality and product.

Came with a flat tire and it continuiodly goes flat after pumping air into it. QA must be bad as they sent me a bad tire and tube.
