The 2021 GT Slammer BMX Bike is an entry level model designed to help teach and improve the technique of new riders. To achieve this design goal GT equipped the Slammer with components such as a gyro so that the bars can spin freely without the brakes engaging, a cassette rear hub, and the popular 20 x 2.3" tire size. If you are a beginning rider, the GT Slammer BMX Bike is the perfect place to start.
