The GT Slammer BMX Bike is an entry-level bike that lives up to its name as you'll be slamming in the streets in no time. GT built this bike with durability in mind thanks to a Hi-Ten steel fork and frame so that it can easily handle a few stacks as you improve over time. It has shorter top tubes and geometry to suit riders on the shorter side, under 165cm. This versatile rig is built with a full gyro brake setup so you can spin your bars and absolutely dominate on the street or in the skate park. The GT Slammer BMX Bike will help you get your skills up to scratch and ride like a pro in no time.

Features

  • Hi-Ten Steel Frame
  • Hi-Ten 2 piece forks
