The Sunday Primer 18" BMX Bike bridges the gap between the 16" and 20" wheel sizes providing a perfect fit for riders who are in between sizes. 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.
