Frequently Asked Questions of Adult Helmet
Measure 3 cm above your eyebrows. Most adult helmets fit 54–61 cm but sizing varies by brand, always check the product size guide. Once on, the helmet should sit level two finger-widths above your eyebrows, with the retention dial snug and less than 2.5 cm of movement in any direction when the chin strap is fastened.
The Consumer Goods (Bicycle Helmets) Safety Standard 2024, fully enforced from 22 September 2025, requires compliance with one of six standards: AS/NZS 2063:2020, AS/NZS 2063:2008, EN 1078:2012+A1:2012, US CPSC 16 C.F.R. Part 1203, ASTM F1447-18, or Snell B-95. The certification label is printed inside the helmet. Every helmet in this collection is compliant.
Yes. All states and territories require helmet use on public roads and shared paths. No adult exemptions exist. Fines range from $25 in the NT to $344 in NSW and Tasmania. Exemptions apply only for approved religious headdress in all states and medical reasons in some jurisdictions.
Most manufacturers recommend replacement every 3–5 years under regular use. Replace immediately after any significant impact — EPS foam compresses on impact and cannot recover, even with no visible damage. Australian UV and heat accelerate degradation. Annual condition checks are worthwhile. Never buy a second-hand helmet.
Yes, and most teenagers should. Helmet fit is set by head circumference, not age. Most teens measure between 54 cm and 58 cm, which puts them in our S/M size — the same helmet an adult with that measurement would wear. A youth helmet on a 14-year-old will usually sit too high on the head, which is exactly where it stops protecting them. Measure first, then use our size chart.
Measure around the head about 3 cm above the eyebrows and match the number to our size chart. As a guide, most teens land in S/M (54–57 cm) and larger teens go into L/XL (57–60 cm). If your teen sits right on the boundary, take the larger size and tighten the retention dial — it gives them room to grow without compromising fit today.
Yes. Our largest sizes cover up to around 62 cm. If you measure above that, tell us before you order — we'd rather point you elsewhere than sell you a helmet that sits too high to protect you. Message us with your measurement and we'll give you a straight answer.

How to Choose the Right Adult Bike Helmet
Get your size right first
Wrap a flexible tape measure around your head approximately 3 cm above your eyebrows. That number, in centimetres, determines your size bracket. Most adult helmets cover 54–61 cm, but sizing varies between brands. Check the size guide on each product listing.
Once the helmet is on, it should sit level, two finger-widths above your eyebrows. Use the retention dial to close the cradle snugly, no gaps, no pressure points. Buckle the chin strap and push the helmet front-to-back. It should move less than 2.5 cm. If it rocks further, readjust or resize.
Adult and teen helmet size chart
| Size | Head circumference | Typically fits |
| XS / S | 52–54 cm | Older kids and smaller teen heads |
| S / M | 54–57 cm | Most teens and smaller adult heads |
| L / XL | 57–60 cm | Most adult heads |
| XL / XXL | 60–62 cm | Larger adult heads |
Match the helmet to your riding
- Road and commuting: Lightweight (200–300 g), aerodynamic, and well-ventilated. Designed for speed, distance, and all-day wearability. Minimal rear coverage, these are not the right call for technical trail riding.
- Mountain biking: Extended rear skull coverage, a visor for sun and debris, and a more substantial shell. Trail helmets typically run 300–450 g. Worth the extra weight if you’re on technical terrain.
- Casual and family rides: Entry-level helmets meet the same mandatory standard as performance lids. What you’re paying more for above the entry level is better ventilation, lighter weight, and a more precise retention system, not fundamentally better protection on a casual ride.
- Scooters and skate parks: A dual certified helmet is the right call. Scooter and skate falls are lower-speed but far more frequent, and often backwards. The rounded shell and extended rear coverage on a dual certified lid protects the back of the head in a way a vented road helmet does not. Every helmet in this collection is dual certified, so it covers commuting on a scooter and session time at the park
Adult Scooter Helmets
Riding an adult or commuter scooter puts you at road speed with none of the protection a car gives you. The same helmet laws apply, and the same mandatory standard applies.
The helmets in this collection are dual certified, which means they’re tested for both cycling and skate-style impacts. That matters on a scooter because scooter falls tend to be backwards and repeated, not forwards and single.
The extended rear coverage on a dual certified shell is doing real work in that scenario.
One helmet, three uses. Commute on the scooter during the week, ride the bike on the weekend, take it to the skate park with the kids. You’re not buying three helmets, and you’re not compromising on any of the three.

Helmets for Teens, Ages 9 and Up
Most teenagers have outgrown a youth helmet by around age 11 or 12. Head circumference is the deciding factor, not birthday. Measure first, then check the chart above.
The bigger problem with teen helmets isn’t fit, it’s that teenagers won’t wear something that looks like a kids’ helmet. A helmet in a drawer protects nobody.
The Triple 8 range in this collection runs in adult shell shapes and adult colourways, including matte black, carbon, navy and white, so it reads as skate and street rather than primary school.
Sizing for teens: most teenagers land between 54 cm and 58 cm, which is our S/M size. Larger teens go straight into L/XL. If your teen is close to the top of a bracket, size up, they’re still growing, and the retention dial will take up the slack in the meantime.
Girls and boys wear the same helmets here. Fit is determined by head circumference, not gender. The difference is colourway, and the Triple 8 Signature range covers everything from matte black through to floral, leopard and rainbow sparkle finishes. Longer hair sits comfortably below the retention cradle on all sizes.
Riding to school, to the skate park, or to a mate’s place all count as public roads and shared paths under Australian law. Helmet use is mandatory and there is no teen exemption, the fines listed further down this page apply to a 16-year-old exactly as they apply to an adult.
Colours and Styles That People Actually Wear
A helmet only protects you if you put it on. That’s why the finish matters more than most safety guides admit.
The Triple 8 Signature Edition range carries the widest colour selection in this collection, black hologram, teal hologram, floral, leopard, rainbow sparkle in black and white, shaved ice, sunset, and rider signature colourways from Sky Brown, Lizzie Armanto, Keegan Palmer, Eliot Sloan and Mike McGill.
If you want something plainer, the standard Sweatsaver range runs matte black, carbon, navy, mint, white, and glossy pink, purple and red, plus gold, silver and black glitter finishes.
Every colourway carries the identical shell, identical certification and identical protection. Choosing the one you like changes nothing about how safe it is.
Helmet Care and When to Replace
Clean with mild soap and warm water only, solvents degrade EPS foam without any visible sign. Store away from direct sun and heat; Australian summer temperatures inside a closed car can accelerate foam breakdown.
Replace your helmet immediately after any significant impact, even with no visible damage. EPS foam compresses on impact and does not recover. For helmets not involved in a crash, most manufacturers recommend replacement every 3–5 years. Australian UV and heat make annual condition checks worthwhile.
Never buy a second-hand helmet. You cannot verify its impact history.
