Swedish designers and geniuses Anna Haupt and Terese Alstin have created Hovding, an "Invisible Bike Helmet," a cowl-like neck piece with a hidden airbag that deploys in 0.1 seconds in the case of an accident.
The deployment is triggered by sensors which pick up "abormal movements" of the bicyclist, and the nylon fabric airbag filled with helium covers your entire head. The Hovding also has a little black box that records the data around the time of your accident, so when you send it back to the company, they can use it as feedback to develop the product.
It's a smart product, considering that bicycling is now quite in due to environmental concerns, but cyclists often don't wear helmets because they don't want helmet-head. The product is now up for sale and costs $597.
