In the same manner as in a periscope, it's actually a set of mirrors that gives you eyes in the back of your head. The first mirror is built into the rear of the helmet. That's the one that records what's happening behind you. This image is taken up by the second mirror, which in turn passes it to the third, on the helmet's visor, just above your eyes. So bikers know what's happening behind their back.
Motorbike, helmet, mirror? Something doesn't sound quite right: what's going to happen in a fall? You can already imagine slivers of the shattered mirror in your eyes... But no! The mirrors are polycarbonate, unbreakable, and they're moulded into the helmet, anyway - they aren't daft at Reevu!
The British company, Reevu, are the developers and it's being hand-assembled by an Asian helmet specialist.
Reevu have been making helmets for 20 years and this revolutionary one took ten years of research and a £2 million investment. It conforms to all current safety standards and will be in the shops in early 2010.
Despite the heavy investment, it does add to the manufacturer’s credit that they have gone in for an affordable price: at about 250 €, it's in the mid-range of the market.
The helmet shell is a plastic and carbon-fibre composite and the two-layer liner includes a crumple zone to absorb impact, with inner liner thickness dependent on helmet size.
Its various features make it suitable for all types of users, for optimal comfort and a better impact resistance.As for the unbreakable mirror, it's an integral optic system known as MROS (Multiple Reflective Optic System).
It's made from polycarbonate, a plastic that's much lighter than steel or glass but much more resistant: it's bullet-proof and jewellers who use it for their windows don't need shutters.
The system doesn't get in the way of your view of the road in front, working on the same principle as a car driver's rear-view mirror.
Testers have reported that they like the fact that they can maintain maximum vigilance in the front and rear, without the muscle fatigue that goes with constantly turning the head on a long ride, nor the time spent looking into the bike's handlebar-mounted mirrors.
The lightest eyewear
Eassun Eyewear was founded in Barcelona in 1992, the year of the Olympic Games.
These ultra-light glasses are an example of the aims of this young, innovative team, whose R&D department has worked with champions such as Carl Lewis, Jeannie Longo and Igor Dominguez to bring style and fashion to eyewear worn by top sportsmen and women.
The objective has been achieved: plastic and high technology have been combined together to create X-LIGHT, glasses that are as attractive as they are comfortable and light.
A polyamide frame, polycarbonate lenses, a choice of eight colours and on sale for less than 50 €: that's class!
