The Sunday Primer 20" is built for riders stepping into full-size BMX who want a proper setup that’s ready to progress straight out of the box. Designed around Sunday’s proven pro-style geometry, it delivers a balanced ride that feels stable, responsive, and easy to control. This version features 20", 20.5", 20.75" or 21" top tube options, making it ideal for mid-sized riders or anyone looking for a versatile, all-round setup. The geometry keeps things predictable and confidence-inspiring, while still offering enough responsiveness for learning tricks, riding park, or hitting the streets. Built from hi-tensile steel, the Primer is tough and reliable, designed to handle regular riding and progression. It comes equipped with quality components throughout, including an Odyssey Springfield U-brake, sealed cassette hub, and wide 2.4" tyres for grip and comfort.
