Frequently Asked Questions
How do I know which size my child needs?
Though using head circumference is not perfect because it doesn't account for different head shapes, it is still the best place to start when choosing helmet size. Using a soft tape measure, measure all the way around the widest part of your child's head, about 1 inch above their eyebrows and ears. Compare the measurement against the 2 sizes: XXS (45-49 cm) & XS (49-53 cm).
Now that I have the Sidekick, how do I make sure it fits my child correctly?
The Sidekick was designed with children's comfort in mind, so there are multiple ways to fine tune the helmet's fit. Refer to the guide below to get acquainted with your Sidekick.
Sidekick Fit GuideWhere can I get the charms?
Ozmo doesn't actually make any charms. We only designed the Charm Slide slot on the back of the helmet (and the button slots on the Cold Weather Kit ear covers) to be compatible with any Croc Jibbitz or shoe charms, because we wanted to give little ones an opportunity to personalize their own helmet. The existing shoe charm market is endless, you can find any character you want!

Looks like it will be perfect for our grandson while riding on back of his parent's electric bike
I used the size guide online and still didn’t fit my child. For a premium product like this I expect a return label for shipping or be provided. Especially for something that is hard to size for a kid.
My kid loves this helmet and looks forward to wearing it. It is far sturdier than his other helmets. And the no pinch chin strap is a parents best friend.
I was really excited to find this helmet, but had to return it due to weight. It met my needs: The winter liner was so clever, ebike safe, and my toddler loved the color (grass stains)... but it was just too heavy for his 3 yo head to comfortably support. Con: I paid $17 to return it after waiting for an eligibility confirmation. That's wild.

Customers said this e-bike certified helmet offers excellent protection with sturdy construction and "well-made" quality. Kids love wearing it with fun designs and the no-pinch magnetic buckle. Highly adjustable fit with easy-to-use dial. Some customers noted sizing runs large and weight concerns for toddlers. "Far sturdier than other helmets."

Our kiddo loves this helmet and so many compliments from other kids and parents too. The clasp is easy enough for her to do it herself but secure that it doesn't pop open unexpectedly either.
Thank you for the wonderful review! We're thrilled to hear the helmet has been such a hit, and not just with your family, but with other kids and parents, too. The combination of kid-approved style and easy-to-use safety features is exactly what we set out to create. Thanks for being part of the Ozmo family!
Helmet looks great and is one of a few helmets my granddaughter actually likes to wear. Solid construction, attention to detail and comfortable to wear. 5 Stars!
Love the helmet for my 9 mo old who rides on the back of my Lectric bike. He’s a bigger boy so the helmet fits him just right. The way the buckle works is a little bit hard to do but I think it’s just user error trying to unbuckle it under his chubby chin.I appreciate there being a helmet madethat’s e bike certified for little kids! Beware of the Super Flash color. It’s a lot more pink than orange. I would have chosen the shark if I knew ahead of time.
The helmet looks fantastic and the kids are so excited to wear it and add their charms. The winter add on is amazing - they can keep it on at the playground as their winter hat! The biggest bonus of all is that they are safe, and I feel 100% confident in this helmet protecting them.
After backing this product on Kickstarter, Ozmo was kind enough to send me a couple of early versions of this helmet to use while I brought my cargo bike on a road trip from Texas to Colorado with my son and all his cousins.
The helmets worked great throughout the trip on guys/girls of all ages. I've used a fair number of kid's helmets and these received the least complaints about comfort of any before. Plus, even after these clumsy kiddos dropped them several times, they look brand new!
Now that we've been home commuting with the helmets for months, they are still holding up just as well as new. I don't know of another eBike-rated helmet for kids, and certainly none that are this well-made.
10/10 would recommend. Thank you for making a much-needed product OZMO!
Fits my 4 year old perfectly. We live in Florida and he hasn’t complained about it being too hot. We went on a couple hour e-bike ride. We did stop about once an hour and he took the helmet off and he wasn’t even sweaty. He’s usually a sweaty kid. If you’re looking for something super durable to haul your kid on an E Bike I’d say this is the helmet for them.
The helmet we bought for our granddaughter is well constructed and attractive. She hasn’t worn it while on a bike yet so we can’t add if she finds it comfortable for any length of time.

Helmet is extremely well-made, has excellent fit, and my granddaughter loves it. The biggest plus is that her parents really like the helmet also. It’s a win-win.
Great
The helmets fit very well and have lots of options for finer adjustments. Highly recommend.
Really excited for this helmet for my 16 month old, and the added peace of mind when I have her on my e-bike. Equally excited for the small to come out as my 5 year old is growing out of her standard helmet and I was wishing there was an e-bike rated helmet her size.
This helmet is fantastic. It fits our 4 (almost 5) year old so well, the colors are awesome, and it gives us a lot of peace of mind for our family cargo bike rides. Highly recommend!
Works great for 7 month old, high quality and love all the adjustable padding and fit.
I give it 4.5 stars because the sizing seams a little incorrect. Otherwise it is a great helmet. My daughter loves the unicorn on it. It is nice to know that she will have better heard protection on the ebikes than the cheap helmet she had before. Overall a great helmet.
Excellent helmet and excellent customer service. My child loves the helmet and the lead engineer and team made sure we got the perfect one. Thank you Ozmo! The fit is very adjustable and allows for precise fit to the head and can be adjusted as the child grows. I got two of them, one for each child. The fit on the toddler/baby is great with all the adjustable straps, padding etc.
Wonderful fit and great adjustments for a custom fit. My 3yr old loves it
My son is unable to drive due to an eye condition and an ebike is essential for family commuting. I wanted the best protection for my grandson, and this helmet fits my criteria. He loves the color and the fit-the magnetic closures are great.
Safe, cute and comfy!
