After first going viral across the web as a concept, the Hovdig Airbag
for Cyclists is now available for purchase! The “invisible helmet” as
its also known, is a great solution for those who refuse to wear a
helmet while cycling. The device is worn as a collar and deploys a
helmet shaped airbag in 0.1 seconds as soon as the gyros and
accelerometers detect you falling helplessly off of your bike. watch the video
