Safety third.

The Bell Youth Sidetrack MIPS Helmet brings together all the bells and whistles your little adventurer needs when they're out on two wheels. With a mountain bike helmet-inspired design, cooling ventilation, and industry-leading Multi-Directional Impact Protection System (MIPS) safety, this helmet is comfy to wear and packs a huge dose of safety into an effortlessly cool package.

The big draw with MIPS is its ability to reduce impact force from rotational forces in the event of a crash. MIPS consists primarily of a strategically anchored liner on the inside of the helmet that looks simple, but serves a complex purpose. That little liner is designed to move independently of the helmet shell to effectively redirect impacts and reduce force. Bell incorporates its ErgoDial Fit System, which makes for an easily customizable fit and a snap-in visor that adds in some style points while keeping eyes protected from direct sun and drizzle.

Good price for a MIPS helmet

I gave it as a gift but have feedback to share

My son's been using this helmet for a couple years now, luckily no big crashes so far. The helmet looks good and fits him well. Only issue he's had with it is the buckle. When he first got it he had difficulty strapping the helmet on himself and would need my help buckling him in. Would be nice if it had one of those magnetic buckles, would be easier for him to strap the helmet on himself.

Bell Sidetrack MIPS Helmet

I've used it several times

Great fit for a 4-year-old. And room to grow! As expected.

What more could a two-year-old want!?

I've put it through the wringer

She absolutely loves the pink design with the flower blossoms around the back. We ended up buying her the "youth" version instead of the "kids" version. It had to be cranked all the way tight when we first bought it, but she was already snug in the kid's one with it all the way loose. Now she's got plenty of room to grow into this one for use over multiple seasons. We also love how the neck strap has a protective area to prevent pinching her cute little neck when putting the helmet on / taking it off.

Insane in the membrane...

I've used it several times

This helmet is great for the young up and coming MTB riders! Got it for my 8 year old nephew and he loves it. It also gives me a little piece of mind knowing he has better than average head protection. Cool color options as well.

My Daughter Needed A New Helmet

I gave it as a gift but have feedback to share

My daughter says its comfortable and likes that it breathes. I like that it has MIPS and that she is willing to wear it. We got the Matte Pink Blossom. She likes pink and I like this pink, but we both agreed we didn't like the flowers, so we painted over the flowers. It took the paint well, so we got it to look more Ziggy Stardust then someones bad wallpaper and now we are both happy.

Great kids helmet.

I gave it as a gift but have feedback to share

My little 5 y/o love it. It fits well, so it doesn't bother her. Therefore, she actually wears it. The MIPS system gives me a bit of peace-of-mind.

Looks great, fits great

I gave it as a gift but have feedback to share

Bought this for a birthday present for my niece. She loves it. It fits perfectly, and it doesn't look dorky, so she's down to wear it.


The name says “kid” and the sizing says “one size” is this a child (up to 54cm) or youth fit (up to 57cm)? Thank you!
