  1. 1

    The foam takes the hit

    Inside is a layer of hard foam (EPS). In a crash it gets crushed – so your skull doesn't. That turns a sudden stop into a slightly longer one, and your brain gets hit with much less force.

  2. 2

    The shell spreads the load

    The thin outer shell spreads the impact over a bigger area and lets the helmet slide on the road instead of catching and twisting your head.

  3. 3

    Less twist for your brain

    Most crashes hit at an angle. Many helmets now have a slip layer (e.g. MIPS) that reduces rotation – a common cause of concussion.

Crashed with your helmet? Replace it – the damage is not always visible.

But…

“It's just 5 minutes to campus.”

A crash doesn't care how far you're going. You can't put a helmet on when you see the crash coming – just like a seatbelt, it only works if it's already on.

“I ride carefully.”

Good! But in about two thirds of bike accidents with injuries in Germany, another road user was involved. You can't control everyone else.

“Helmet hair.”

Fair. But hair grows back – brain cells don't. Keep a small comb in your bag and you're done.

“Helmets look stupid.”

There are a lot of slim, urban helmets now. And honestly: nothing looks worse than a hospital gown.

Wear it right: 2-2-2

A loose helmet can't protect you. Check these three things – with two fingers each.

Eyes

The front rim sits two fingers above your eyebrows – level, not tilted back.

Ears

The side straps form a “V” just under each ear – like two fingers spread around your ear.

Mouth

Buckle up: two fingers max. between strap and chin. Yawn – the helmet should pull down.
