Several years ago French company Bumpair invented an inflatable helmet. They partnered with a scooter share company in France, and offered this wild feature: When you unlock one of their scooters, you hit a button on the app and the helmet auto-inflates!
That was version 1.0 of the helmet. The new 2.0 version will be offered as a portable bike helmet that complies with the EN-1078 safety certification and, the company says, offers "up to 4x more [protection] than a classic helmet." The idea is that you can deflate it for storage, then pump it up with a small (I assume included) hand pump when it's time to go.
The company says the Bumpair 2.0, which is not quite ready for primetime, will retail for €255 (USD $287).
