The Primer 18” is the ideal choice for riders who’ve outgrown a 16” but aren’t quite ready for a 20”. The shorter chain stay, lighter wheels and size-specific, pro-style frame geometry makes it the go- to bike for serious BMXers in this size range. 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.
