The Primer 18” is the ideal choice for riders who’ve outgrown a 16” but aren’t quite ready for a 20”.
The shorter chain stay, lighter wheels and size-specific, pro-style frame geometry makes it the go- to bike for serious BMXers in this size range. The Primer is packed with quality parts like Odyssey Springfield Brakes and a fully sealed cassette hub for reliability that you can count on every time.

We are proud to introduce our 2021 Sunday complete bikes. You’ll quickly find that our new line is full of improvements once again this year. We are excited to introduce “Park” models in both the Primer and Forecaster categories. With a model-specific geometry that features accents like a lower standover height and an Odyssey Gyro kit with dual cables top and bottom, both the Primer and Forecaster Park models are built to shred right out of the box.
We are also happy to announce that Broc Raiford recently joined the Sunday Pro Team and we were able to include his signature Forecaster complete bike in the 2021 line. Additional improvements can also be found on our popular High-C 29er bikes. This year’s model features V-brakes, an Avid brake lever, a quick release seat post clamp for 27.2 posts, a revised gear ratio and an all-new handlebar design.
From our entry level 16” Blueprints to our 100% aftermarket Soundwave Special, the entire 2021 line features the vibrant colors and finishes that Sunday is known for and, as always, you can count on the durability, manufacturing quality and modern spec that has made Sunday the go-to brand for riders shopping for a new complete bike. We hope that you’ll enjoy checking out the new Sundays as much as we enjoyed making them. Thank you for your continued support!
