How to fit a Child Bike Helmet:
Position the helmet to sit LOW on the child’s forehead with two finger-widths above the eyebrows. The child should be able to look upward and see the front rim of the bicycle helmet. The left and right side straps form a “Y” and meet right below the ears. Allow two fingers space under the chin strap. Ask the child to shake from side-to-side and up-and-down (no or yes motion). The helmet should not wobble.
