Cardboard bicycle helmet is safer than the regular one

June 8, 2011 · 4 comments

Student designer Anirudha Surabhi hopes that cardboard helmets will revolutionize helmet industry. His argument is that standard helmets made of expanded polystyrene absorb little impact energy, but rather pass it on to the head. Consequently, modern helmets protect your head only in 16% of cases during a crash.

Anirudha’s helmet called Kranium is made of regular cardboard and absorbs 4 times the amount of impact energy when compared to regular cycling helmets and therefore protects your head much better.

The helmet was smashed five times in a row and still passed the British Standard (EN 1078) test.


The designer hopes to assemble the helmets based on custom user requests according to the head shape and color preference.

Fair point, but there is probably a layer of plastic over the cardboard.

wonder how well it will do in major crashes, when there’s more force involved. True, polystyrene would transfer more of the crash force to your head, but wouldn’t the cardboard simply collapse in a heavy fall?

Cycle helmets are only designed to cope with a fall or slowish crash. They don’t protect your neck etc. It’s even questionable whether they reduce head injury, because they increase rotational injury of brain. Head hair serves to reduce rotation injury, a helmet increases it. Best is use the safety device already in your skull.
