Invisible Bike Helmet (+VIDEO)
Itâs not a hoax, itâs modern life. Yes, there are invisible helmets available for the bikers to buy NOW. The HÃ¶vding (that’s Swedish for “chieftain”) took seven years and $10 million to develop from concept to product. It is actually a helmet-shaped airbag that deploys on demand to save your skull, and spends the rest of its time out of the way warming your neck. You can purchase the invisible helmet for just 4,000 Swedish kronor or USD600.
