Cyclists in Europe now have another helmet option to help protect against concussion and brain injury.

The Kranium cardboard helmet is the brainchild of London designer Anirudha Surabhi. Surabhi came up with the idea after a bike accident left him with whiplash, a concussion, and a mangled helmet. He figured there was a better way to protect the brains of cyclists.

Other concussion-reducing designs include the Hovding airbag helmet that deploys in an instant to cover and protect the head in the event of a crash.
