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!
How do I take care of and store the helmet?

Answer














I have Ozmo helmets for my 5.5 year old and 2.5 year old. They are amazing and I wouldn’t let my kids wear anything else.
The helmet runs big. I picked a sized based on my kid's head circumference, but it doesn't have a tight fit yet. I think we've only used used twice for this reason (using a different helmet until this one fits correctly), but it already has scratches on the white paint. I do love the easy buckle, very convenient.
Thank you for taking the time to leave a review. I'm glad the magnetic buckle has made getting the helmet on and off a little easier.
We're sorry to hear the fit hasn't been quite right yet. Head circumference is the best starting point for sizing, but sometimes a few simple adjustments or a different size can make all the difference. We wish we'd had the opportunity to help before you set the helmet aside.
Please feel free to reach out to us at support@ozmohelmets.com. We'd be happy to help troubleshoot the fit and explore the best solution so your little one can get back to wearing their Ozmo helmet with confidence.
I measured accordingly but the helmet shell fits really large, there is a large gap between the shell and inside straps. It would not work in the toddler bike seats which is what I purchased it for. I tried to exchange however the shipping is not included, you have to pay to ship back then wait for it to be assessed before they will exchange or refund. Check shipping prices prior to purchasing. For me it wasn’t worth it. I now have an unusable helmet laying around.
We're sorry to hear the helmet didn't work out for your little one. Before approving the return, we did try suggesting a few fit adjustments to see if we could make the XS work, but unfortunately it sounds like it still wasn't the right fit.
Because we don't currently offer direct exchanges, our process is to return the original helmet and place a new order for the correct size. We understand that return shipping can be frustrating, and we appreciate your feedback as we continue evaluating ways to improve the experience.
If there's anything we can still do to help, please don't hesitate to reach out to us at support@ozmohelmets.com.
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!
I bike everywhere in my e-cargo bike with three kids and they absolutely love their helmets. I love that their heads are more protected because of the higher level of certification these helmets have. Bonus that the kids got to pick a fun design.
Thank you so much for your thoughtful review! It means a lot to hear that your family is enjoying the helmets, especially knowing how many miles you spend riding together.
We designed the Sidekick to pair higher-speed e-bike protection with features kids actually get excited about, so it's wonderful to hear your little passengers love picking out their designs, too. Wishing your whole family many more safe and fun adventures together!
