My 8 yr old son has a 21.5" head circumference. This helmet fits a bit loose right now. It doesn't move when he shakes his head without the chin strap, tho, so we're keeping it. Seems to make my kid want to ride his bike more, so win win.

Very cute helmet, kid looks funny. Everyody looks at my son when he bikes with this helmet on his head. But this helmet is not really comfortable to wear, it has no regulation. I suppose it cannot save a head when biker is fallen down. So I would not recommend it for young bikers, it fits for more professional bikers, who falls rare. It is more fore fun and cool locking

My 6 year old son loves the fun look and cool light up feature. I also enjoy the light up feature as it enables me to see him riding in the neighborhood when it’s getting darker.

My kid LOVES this helmet. It has a little button to turn on/blink/off the lights in the mohak. It provides great safety while running his bike and he feels like the COOLEST kid in the neighborhood. Highly recommend!

Christmas present for my son. Didn’t even realize the spikes light up and also can be set to flash so that was a nice surprise!

I wanted a fun helmet to go with my new green bike! Though it's marketed for kids, it fits perfectly on my 22.5" adult noggin. I figure that part of bike safety on the road is being noticed by drivers, and it's hard to miss this helmet! So far, it is comfortable, and it was easy to adjust the chin strap to get the right tension. The helmet is light. It's cut just high enough over the ear that it doesn't press on my glasses. The lights turn on and off using an easy to feel for button on the back

I bought this helmet for my roller son, it is looks like aggressive helmet for professional rollers :) Only one thing I have for complaining, there is not chin clamp :(It has buttons which controls the top lightning - that is killer future, I think!So in summary, my son is happy and that is the main thing ;)

This is a really nice helmet, but it was too small for my 8yr old boy. they really should have larger sizes available, i'm sure there are plenty of adults that would like this helmet also!

My 8 year old is aspiring to become a skateboard punk like his older brother and like his dad used to be back in the 90s. This mohawked helmet fits the bill. He finds it very comfortable, and I feel like it will protect him well during his skateboard and bike adventures.

I had to return the helmet because someone else gave my grandson one for Christmas. However it was well made and very cool looking for any younger child. Very lightweight. Lots of good protection for a young bike rider that wanted a cool bike helmet

This was a present for my granddaughter. She wanted the spikes on top. Very good quality and lightweight. Fits her well and provides good protection.

Inside is padded too well or atleast not enough in my opinion but still pretty cool helmet and it matches my sons bike so he likes it

Got this for my 9 year old son. It is such a cool looking helmet, easy to adjust, sturdy and comfortable for him. Thanks for attention.
