Size: Universal Child (47-54 cm)


Features

  • FUSION IN-MOLDING POLYCARBONATE SHELL - A process pioneered by Bell bonds the helmet's outer shell to the EPS foam liner to create a sturdier helmet.
  • INTEGRATED MIPS (MULTI-DIRECTIONAL IMPACT PROTECTION SYSTEM) - MIPS stands for Multi-directional Impact Protection System, which is a leading slip-plane technology inside the helmet designed to reduce rotational forces that can result from certain impacts.
  • ERGO-FIT - What was once ErgoDial now has an improved dial feel and function (no longer requires a push to turn) and is more sleek and less bulky.
  • NO-TWIST TRI-GLIDES AND SWEAT GUIDE - Quick-adjust fasteners that help keep straps flat and properly positioned. Sweat Guide pad design pulls moisture away from the brow pad and away from eyewear.
  • SPECIFICATIONS - Universal Youth (47-54 cm) and Universal Child (50-57 cm) Sizes. Important: always take a head measurement. Head sizes and shapes can vary, even within an age range. Using a helmet that does not fit can be dangerous; 14 Vents.

  • Super Tough Super Tough
I bought this last year because I really liked the safety rating and it was a design my daughter liked. She’s used it quite a bit over the past year+ with no issues. Just last week my daughter left her helmet in the driveway. My daughter was elsewhere and not anywhere near the helmet when my mother in law went to leave and accidentally backed up and drove over part of the helmet with one wheel. It held up amazing after having been driven over - I’m incredibly impressed. As you can see from the pictures it was definitely damaged with cracks and dents, but considering it was partly run over it held up nicely and I didn’t see any damage where the head would be and makes me confident in the quality and safety of this helmet! We are definitely getting another one of these to replace it! ... show more

I got this for a 6 y/o and he loves it. It's comfortable and snug like a bike helmet should be. It was easy to adjust the straps.

  • Saved my girl's life.
My 8 year old girl asked for a hoverboard for her birthday and we got her that as well as the buggy attachment. First time riding in the buggy, she lost control and sped right into a parked car which was a large pick-up truck. Due to the high rise of the truck, she drove at full speed right under it and hit her head on the bumper. We rushed her to ER in an ambulance. Thankfully, after all the x-rays and scans, she is fine with just some minor bruises on her chin and a couple of chipped teeth. Helmet took the brunt of the blow to the head, and has relatively deep gauges and bumps in it from the impact. CT Scan showed no injuries to the brain, no neck or spine injury either. She would not have survived this impact without a helmet. Aside from counting our lucky stars and thanking her guardian angel, the helmet did it's job. ... show more
