A cardboard cycle helmet? And we thought we’d seen it all!

A cardboard cycle helmet? Sounds about as much use as a glass mallet! But no, it’s real. And it’s not the hairbrained idea of some crackpot inventor holed up in a shed – Germany’s Abus have actually put it into production. And here it is – the Abus Kranium AKS 1 Limited Edition.

Okay, so it’s not entirely made from cardboard – it’s got a thick plastic outer shell and EPS foam inner. Which begs the question, why bother with the cardboard at all?! Is it just an attempt to extract cash from the green lobby loons? Not according to its creator, Anirudha Surabhi.

The Kranium is made from recycled paper, but Ani says it’s protection that’s the driving force behind it, not eco-friendliness. He reckons it can absorb three times the amount of energy of a regular EPS lid and says it can stand up to multiple impacts too. Won’t it get soggy in the rain? Nope, the card’s been treated with a waterproof solution.

The AKS 1 is aimed at commuters but if the technology lives up to Ani’s claims, there’s no reason it couldn’t be used in trail lids and full-faces too. Check out the video and pics below to find out more. Got a friend who’s a hipster or city centre wobbler? They can pick one up from London’s Velorution for £79.99.

In this picture you can see just how thick that plastic shell is. That might go some way to explaining the lid's 535g weight. Picture by James Costley-White
