No more guesswork, no more fidgeting, no more tantrums. The new Bell and Giro kid's helmets with OneStep fit make biking more fun and safer in one easy step. Before the first ride, simply adjust the main strap, and the head-hugging OneStep fit system does the rest. If that's not enough, the super fun integrated flashing lights will turn that frown upside-down. And the peace-of-mind will have you smiling too.
