There’s a good chance you learned to ride on a BMX bike. Not only did it look cool, but it had everything you needed: a tough steel frame and fork, knobby tires on 20” wheels, and a single gear for any situation. The Nitrus is that bike, a traditional BMX bike with classic style. Simple, streamlined, and fun. With this familiar setup and features like an easy-pull brake lever and an extra-durable seat, the Nitrus is a solid bike for any young dirt ripper. This model fits riders 44”-54” tall, aged approximately 4-9 years old.
