Gloss Black Previous Model • View Current Bikes »

The Primer 16” is better than ever and perfect for younger riders with lots of tricks up their sleeves. The Primer rides like a pro-level bike that has been scaled down to meet the needs of smaller BMXers. Sunday’s unique geometry helps them quickly adapt to bigger bikes as they grow. The Primer is packed with quality parts like Odyssey Springfield Brakes and a fully sealed cassette hub for reliability that you can count on every time.
