Kids Bike Helmets
Age is the starting point, head circumference is the answer. A large two-year-old and a small six-year-old can wear the same size, which is why both of our kids helmets are sized in inches and adjusted with a rear dial rather than sold by age alone.
The two kids models
- Ages 1-8, 9.3 oz
- The one to start with for a first bike, a balance bike or a scooter. A bug mesh sits behind the front vents, and some colors ship with a matching knee-and-elbow pad set.
- Ages 3-14, CPSC certified
- Certified to 16 CFR 1203 with a skate-style shell. It is heavier at 14.4 oz because it covers more of the back and sides of the head, which is what schools and clubs usually ask about.
How to size a kids helmet
Wrap a soft tape about one inch above the eyebrows, keep it level, and read it in inches. Do this while your child is calm — a measurement taken mid-tantrum will be wrong and you will return a helmet that was the correct size all along.
Then check the fit on their head: the front rim should sit about two fingers' width above the eyebrows, and when you ask them to shake side to side, the helmet should move with the head rather than wobble on top of it.
| Model | Sizes | Typical age |
|---|---|---|
| Kids Helmet, Ages 1-8 | XS 18.8''-19.7'' / S 20.1''-21.2'' | 1-8 |
| Kids Helmet, Ages 3-14 | S 20.1''-21.7'' / M 21.7''-22.8'' | 3-14 |
What to check before you buy
- Weight and ventilation
- A child takes a helmet off when it is heavy or hot. 9.3 oz with 14 vents is the light option; 14.4 oz with 18 vents is the one with more coverage.
- Pads in the same order
- Several colors of the 1-8 model ship as a set with knee and elbow pads, which is usually cheaper than buying both separately later.
