Not too big. Not too small.

The Primer 18 is just the right size.

Built With Freestyle in Mind

The moment you hop on one of our bikes and pop that first wheelie, you’ll notice right away what sets our 18″ bike apart from the rest. We designed our frames with proper geometry that makes it respond just like a regular 20″ BMX bike. This means the little ones will have zero problems getting rad with the big kids.
