The GT Performer Freestyle BMX Bike is a versatile street machine which can help you learn how to tear up the tarmac. GT built this bike to be super tough as there are always plenty of bumps on the road, but with a Hi-Ten steel frame and fork this bike can handle the rough and tumble. You'll be powering along on GT Power Series Cr-Mo 3 piece cranks and GT Low Profile platform pedals for maximum power transfer for when you want to hit the ramps with some serious speed. The 18 inch tyres are suited to the rider who isn't quite ready for the full size BMX. The GT Performer Freestyle BMX Bike is an affordable entry-level BMX bike that is a sweet ride and one of the best BMX bikes for sale in this price range.


  • Hi-Ten Steel frame
  • Hi-Ten Steel Fork
