As surprising as it sounds, a prototype bike helmet design made of cardboard has been picked up and is now available at bicycle shops in the UK.

The Kranium cardboard bicycle helmet, designed by Royal College of Art student Anirudha Surabhi, has been picked up German security devices manufacturer Abus and is now available as the Kranium AKS 1 helmet. The helmet’s honeycomb cardboard structure – dubbed “Dual Density Honey Comb Board,” or D2 is reportedly 15 percent lighter than similar foam-cored helmets, and – due to its ability to flex – is able to withstand three times as much impact energy as conventional helmets during a collision.

Inspired by the resiliance of the beak and head of a woodpecker, the original safety testing for this revolutionary helmet was done by safety testing laboratories such as Germany’s Technischer Überwachungs-Verein and Head Protection Evaluations, based in the UK. This deceptively simple safety device can stand up to repeated impacts. In testing, one of the helmets passed British safety standards after five impacts. Users of traditional helmets are advised to replace their helmets after even one impact.

Now for pre-order, this new bike helmet is priced at £79.99 (US$129).
