A motorcycle helmet protects as the shell and soft foam stops the outside to come into your brain. It works like a pseudo-skull, protects the thing inside and can be used again
A bicycle helmet stops by crushing hard foam and the outside layer of plastic helps by skidding across without gripping the road. Works like a disposable skull, only to be used for one bad situation and only one hit.
Completely incorrect, sorry -- your motorcycle helmet is not meant to be used again if the foam inside is crushed. They use the exact same foam for both your motorcycle helmet and your bicycle helmet. They both use polycarbonate foam. The additional padding you have inside of your motorcycle helmet is merely for comfort you have the same thing in your helmet just less of it, this padding is not for protection. Beyond the padding is a layer of the foam used to protect from impacts. Both helmets came from the same technology and even the same company -- Bell.
