The Primer 18 is the ideal choice for riders whove outgrown a 16 but arent quite ready for a 20.

The shorter chainstay, 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.
