Sunday Primer Park 20" BMX Bike
The Sunday Primer Park 20" is built for riders who want to focus on park riding while still having a solid all-round BMX setup. Based on Sunday’s proven Primer platform, this version is updated with park-specific geometry and a full gyro system, making it ideal for learning barspins, flowing transitions, and progressing quickly.
With a 20.5" top tube, this bike offers a balanced fit for mid-sized riders, giving enough room for stability while keeping things responsive. The shorter 12.7"–13" rear end keeps the bike quick for manuals and technical riding, while the steeper 75.5° headtube angle keeps the front end sharp and precise.
What sets the Park model apart is the inclusion of an Odyssey Gyro system, allowing full bar rotation without cable tangling—perfect for riders looking to learn barspins and more advanced tricks. Combined with Odyssey Springfield brakes and Path Pro tyres, the bike delivers reliable performance straight out of the box.
Built from hi-tensile steel, the Primer Park is tough and designed to handle progression, while components like the sealed cassette hub, Sunday Freeze stem, and FSA headset keep everything running smooth and low maintenance.
If your riding is focused on skateparks, transitions, and learning tricks, this is one of the most complete and capable entry-level bikes available.
