Bell's OneStep™ Fit System self-adjusts to the correct size, eliminating the yanking, adjusting and fussing often associated with fitting kids’ helmets.The only adjustment needed is on the initial fitting—simply snap the buckle closed and make the one-time adjustment of snugging the chin strap to the proper length. That’s it.  The helmet will fit properly and securely every time your little rider heads out. The OneStep fit system also features built-in flashing lights for added visibility.

The integrated bug net lets air flow in, but keeps pesky bugs out.

Bell’s PinchGuard buckle is specially designed to prevent kids from pinching their neck when they secure their helmet.
