The GT Air BMX Bike is built to allow riders starting out in BMX to get some serious air. When you get some air you need to land comfortably and the Hi-Ten Steel frame and forks can handle some rough landings on any ride. While the GT Power Series 3 piece cranks are durable and reliable so that you can trust in your BMX bike. The Air is an all-round capable BMX bike which is built with removable tab holes so that you can upgrade to gyro if you need. The finishing touch is the semi sealed cassette hub with a 25t sprocket and a 9t driver for optimised freestyle performance. The GT Air BMX Bike does it all, on the ground and in the air, this bike is a fully loaded shredder.
