A helmet is a protective headgear used by bike or motorcycle riders. The primary goal of a helmet is safety - to protect the rider's head during impact, thus preventing or reducing head injury and saving the rider's life.

The invisible bicycle helmet uses rechargeable battery-powered accelerometers and gyroscopes that detect the typical motions involved in a bike crash. They trigger a tiny gas inflator which instantly fills a nylon airbag with helium.

After detecting an approaching impact, the nylon airbag which was embedded inside the collar gets inflated and covers the head as well as the entire neck unlike the traditional hard plastic helmets.

From just fiberglass in the 1960s, at least three different materials are now available for the manufacturing of shells, namely pure carbon fiber, composite fibers, and high-resistance thermoplastic. Each of these materials already tends to identify the type of helmet we are dealing with.

Modern helmets are made of lightweight and strong materials like Carbon Fiber, Fiberglass, Kevlar, and composite materials. They do a much better job of keeping you safe while also making the helmets lightweight and comfortable.
