GT Air 20"TT BMX Bike-Guinness Black

At home in the neighborhood or the skatepark, the Air is the perfect first bike. The frame geometry is quick responsive allowing the bike to handle easier as the young rider builds up their strength. Spec'd with a 25t sprocket, a 9t cassette rear hub, and large volume tires, the Air lets the rider fit in with their friends without a high price tag.
