We're excited to introduce an updated Primer line of bikes for all the young riders out there. Our Primer 16" & 18" bikes are now built around a newly-designed lightweight aluminum frame; all while retaining a classic look and durability. The aluminum frame upgrade will be an added advantage to young riders who are just starting out, and the new seat/post combo provides a comfortable level riding position.

Using Sunday's proven geometry, the Primer rides like a pro-level bike that has been scaled down to meet the needs of smaller riders. These bikes are packed with quality parts like Odyssey Springfield Brakes, cables and a fully sealed cassette hub for reliability that you can count on every time. 18” models feature Odyssey Path Pro tires.
