Primer 18" 2020 BMX Stunt Bike

Engage in your initial tricks with the 18" Primer

The Primer 18" by Sunday is an enjoyable and straightforward freestyle BMX designed for children and budding riders not yet ready for a 20". Every component on the Primer 18" adheres to BMX geometry, ensuring a far simpler transition to a fully sized setup compared to switching from a typical child's bike.

In this 2020 model, the team at Sunday opted to include a fully sealed cassette hub, offering smooth rolling and reduced maintenance requirements.
