Bicycle helmet design to Australian standards.

The Australian standard for bicycle helmets is AS 2063.1: Lightweight protective helmets. When released in 1977, it was one of the first standards to address the needs of bicycle riders. Its requirements were so stringent that it was not until 1982 that a helmet could be approved by the Standards Association as conforming to the standard. The standard is only design restrictive in that it requires a hard shell, a means of absorbing an impact and a retention system.
