Description
Experience your initial tricks with the 18" Primer
The Primer 18" by Sunday is designed to be an enjoyable and user-friendly freestyle BMX for kids and younger riders who are not quite ready for a 20". Every component of the Primer 18" adheres to BMX geometry, ensuring a smoother transition to a fully sized setup compared to starting from a typical child's bike.
For the 2020 model, the team at Sunday included a fully sealed cassette hub, contributing to a fantastic ride and reducing the need for maintenance.
