The 2021 Sunday Primer 18" BMX Bike bridges the gap between the more common 16" and 20" wheel sizes that leave many riders on a bike that doesn't fit right. Riding something that is either too small or too big makes learning new tricks next to impossible making the 18" wheel size an amazing addition to the Sunday lineup. The Primer 18" is built with components that create a ride that is both durable and low-maintenance, an amazing combination for riders wanting a no nonsense bike.

This bike is perfect for my 6 year old son. He’s 4’ tall and will be able to ride this for a few years. It’s a solid bike with great components. The only downside is the bright red color looks more coral/pinkish in person.
