How about an invisible biking helmet? Or one that you can wear as a scarf, a neckie?
Enter Hövding from Sweden.

The latest innovation in bike gear? A nifty collar that inflates to become an airbag at the first sign of trauma. And you're safe from helmet hair, too.

"Bike helmets discourage cycling. An Australian study on mandatory helmet laws concluded that laws that required cyclists to wear head protection actually decreased the number of cyclists on the road. The implication of this study? The fewer cyclists on the road, the less likely drivers will be accustomed to sharing road space with cyclists, ultimately increasing the hazards faced by cyclists and further dissuading people from hopping on their bikes."
