BMX Helmets

A BMX helmet is built for repeated low-speed impacts on hard surfaces, so it prioritises coverage and durability over airflow and weight.

Most use a hardshell construction:

The outer shell and the liner are formed separately and then laminated together, which gives excellent impact protection, deeper coverage at the back of the head and a lower price, at the cost of ventilation and a bit of extra weight.

A road or cross-country helmet does the opposite. These are light and airy, with less coverage and a shell moulded straight onto the foam.

That difference in shape is why a BMX helmet sits lower on the head and wraps further down the back and sides than the helmet you'd wear on a road bike.

If you're racing, the rule is clear:

AusCycling's technical regulations state that "for BMX racing, full-face helmets with a fixed non-detachable mouthpiece are mandatory at all AusCycling sanctioned events."

A full face with a removable chin bar does not satisfy this.

Officials also won't pass a helmet that's worn, discoloured or in a state of disrepair.

For BMX freestyle there is no full-face requirement.

The general rule applies, which is a correctly fitted helmet meeting AS/NZS 2063 or an accepted equivalent.

Most park and street riders wear an open face or full cut.

So:

Racing means full face with a fixed chin bar. Freestyle means your choice.

If your kid is about to start racing at a local club, that's the one thing you can't substitute.

Level it.

The helmet should sit level, with about two fingers' width between your eyebrows and the front edge. Tipped back is the most common error and leaves your forehead exposed.

Set the side straps.

The straps should form a V that meets just below and slightly in front of each ear.

Do up the chinstrap.

You want about one finger's gap between the strap and your chin. Open your mouth wide and you should feel the helmet pull down.

Shake test.

Nod and shake your head firmly. The helmet shouldn't slide, rock forward or shift on your skin. If it moves, tighten the retention dial or try a smaller size.

Check the padding.

Most helmets include multiple pad thicknesses. Use them to fine-tune the fit rather than over-tightening the strap.
