The 2021 GT Air BMX Bike is an entry level model designed to teach and improve the freestyle technique of new riders. To do this GT equipped the Air with components such as 3-piece chromoly cranks featuring a modern 25 x 9 gearing, a cassette rear hub, and the popular 20 x 2.3" and 20 x 2.2" tire sizes for front and rear respectively. For a first bike, the GT Air soars.
