For those of us who ride regularly, the daily threat of colliding with an oblivious driver looms large. The Hövding 3 might just save your noodle in a bad situation, especially if the notion of wearing a regular bike helmet is anathema to your two-wheeled freedom. It’s an inflatable neck collar that deploys into a padded helmet in a mere 1/10th of a second when the built-in accelerometers sense you’re falling from your bike. The third-gen version of the Airbag Helmet promises to be more comfortable and adjustable, and it can connect to your smartphone to automatically call emergency services post-accident. The Dollar Store astronaut look is just a bonus.
