The Hoyding helmet is a simple yet brilliant concept: it is an airbag helmet that deploys in the case of a crash.

The "collar" is wrapped around your neck and zipped up, and that's it. That's where it gets its "invisible helmet" moniker.

Research and development work started in 2005, with thousands of cycling accidents being re-enacted using stunt riders and crash-test dummies to collect the specific movement patterns of cyclists in accidents.

Based on the collected data, the company developed an algorithm that can distinguish normal cycling from accidents so that the airbag knows when to deploy.
