  • 18" top tube length suits a younger rider height (130cm - 155cm)
  • Lightweight 20 spoke front wheel helps get the front off the ground
  • 36 hole rear wheel stays strong
  • Loud rear cassette hub is sealed bearing
  • Modern geometry suits all styles of riding

    The 18 inch United Recruit BMX bike is perfect for a smaller rider to throw the bike around. A very smart choice of less spokes on the front wheel gives more chance to lift a lighter front end, while a sturdy 36h wheel keeps the United Recruit 18" dependable. Sealed bearings where it counts and smaller, responsive geometry gets your progression on track!
