Which BMX helmet size fits my child?
Head circumference — not age — is the correct way to size a BMX helmet. Measure around the widest part of the head, above the eyebrows and ears, with a soft tape measure. Use this framework to match the measurement to the right shell.
Toddlers: 45–51cm (XXS/XS)
Most children aged 2–4 fall in this range. The Triple 8 Lil 8 Dual Certified Youth Helmet starts at 45cm. At this size, a dial-fit adjustment system matters most — little heads grow fast.
Kids: 51–58cm (XS/S and S/M)
Most children aged 5–12 measure between 51cm and 58cm. The Triple 8 Little Tricky, Globber Kids LED, and Hornit LED helmets all fit this range. The Triple 8 Wipeout Dry Erase targets 51–55cm and suits first-time BMX riders aged 5–8.
Teens and adults: 58–64cm (M/L and L/XL)
The Triple 8 THE Dual Certified Sweatsaver Signature Edition and the Nutcase Street w/MIPS both cover 58–64cm. The Nutcase in Large fits 60–64cm — the right choice for adults who ride BMX tracks, pump tracks, or skate parks.
A correctly sized BMX bike helmet sits level on the head — no more than two finger-widths above the eyebrow. The chin strap should be snug with one finger fitting between strap and chin. The Triple 8 Sweatsaver range includes an internal dial-fit system for micro-adjustment as children grow.
Are these BMX helmets compliant with Australian safety standards?
Every helmet in this collection meets the mandatory AS/NZS 2063 bicycle safety standard, enforced under Australian law by the ACCC. You can verify this mandatory standard at the Product Safety Australia website.
The dual-certified models — Triple 8 Lil 8, Triple 8 Little Tricky, and Triple 8 THE Dual Certified Sweatsaver — carry both AS/NZS 2063 (bicycle) and AS/NZS 3838 (skateboard) certification. That dual certification matters if your child uses the same helmet for BMX and scooter or skate park sessions.
What is a full face BMX helmet and do you stock one?
A full face BMX helmet adds a chin bar and extended jaw coverage compared to an open-face shell. Full face models suit riders on dirt jumps, race tracks, and pump tracks where forward or downward falls put the chin and jaw at risk. They are not required for skate parks or casual trail riding, where an open-face certified to AS/NZS 2063 gives full legal compliance and sufficient coverage. If you need a dedicated full face BMX helmet for track or race use, contact the Xchange Sports team and we will source the right model for your discipline and head size.
What makes a BMX helmet different from a standard bike helmet?
A BMX helmet uses a lower-profile, rounder shell compared to a road cycling helmet. That shape delivers better rear and side coverage for the falls common in BMX and skate park riding. The Nutcase Street (Blue Steel) w/MIPS adds a slip-plane liner that reduces rotational force to the brain during angled impacts, a technology recommended by children’s head injury researchers at BetterHealth Victoria. For riders spending time on ramps, trails, or pump tracks, that added protection layer is worth the premium.

LED helmets for early-morning and low-light rides
Two models in this range include built-in LED lighting: the Hornit Kids Bike Helmet with LED Lights and the Globber Kids Helmet with LED Lights. Both make a rider visible in low-light conditions. early school runs, late-afternoon park sessions, or overcast winter days. The LEDs integrate directly into the shell with no external battery cases or clip-on attachments. If your child rides before or after school, these two models are the practical choice over a standard shell.
Get your helmet before the school holidays rush
The Triple 8 and Globber ranges move fast in the lead-up to Christmas and the back-to-school period in late January. Stock on popular colourways — particularly the Sweatsaver Signature Edition and the Wipeout Dry Erase in teal, sells through several weeks before the holiday. Order now to lock in your size and colour. Check current dispatch timeframes and cut-off times on the Xchange Sports shipping and delivery page. Orders placed before 2pm on weekdays dispatch the same day.
Don’t skip the accessories
A BMX helmet works harder as part of a complete protection setup. Knee pads, elbow guards, and wrist guards reduce injury risk on the same falls a helmet is built for. Browse the Xchange Sports accessories collection to complete the kit in one order.
When to replace a BMX helmet
A helmet that takes a significant impact needs replacing immediately — even with no visible damage. The EPS foam liner compresses on impact and does not recover. Triple 8 helmets include a sweat-wicking Sweatsaver liner that also signals when the fit has loosened over time. Nutcase includes an impact indicator in select models: a colour change inside the liner that flags when the shell has absorbed a crash-level force. Re-check dial-fit tension every 4–6 weeks for growing children, and replace any helmet that has taken a direct impact regardless of visible damage.
