Sunday Bikes stands for innovation. Period. With 41-Thermal® technology, they build frames and forks that survive the toughest street riding. No toys, just pro-level gear—whether you’re just starting out or already grinding double pegs.
Your bike arrives in its original packaging, untouched and straight from the box. 100% brand new, not a display model.
Everything you see here is actually in our warehouse. Order by 2 p.m. and we often ship it out the same day.
We are an authorized Sunday dealer. Full warranty, full support, and a direct line to the manufacturer.
The perfect entry-level BMX. Sealed bearings, sturdy crankset, and Sunday geometry at an unbeatable price.
The Sunday Primer is a solid 20-inch BMX for beginners who want to start with a proven BMX geometry. The steel frame provides a robust foundation, while four available top tube lengths allow for a proper fit. Odyssey Path Pro tires, Springfield brakes, and the sealed cassette hub ensure a reliable setup for first tricks and fast progress.

Sunday (and Odyssey) use a special heat treatment process for frames, forks, and crank arms. This makes the steel so strong that Sunday offers a lifetime warranty against bending and breaking on all 41-Thermal® parts. If it carries the logo, it lasts.
