We're excited to introduce an updated Primer line of bikes for all the young riders out there . The Primer 18" is now built around a newly-designed lightweight aluminum frame, all while retaining a classic look and durability. The Primer 18" is the ideal choice for riders who've outgrown a 16" but aren't quite ready for a 20". The aluminum frame upgrade is 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 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 you can count on every time. 18" models feature Odyssey Path Pro tires.
