We first covered the Reevu helmet, with its built-in rear view mirror for motorcyclists, back in 2005. It's an excellent idea - a rider's vision and situational awareness are huge components of road safety. The more you know about what's happening around and behind you, the more options you've got in an emergency or a simple lane change situation. Well, it's been a long road to the market, but Reevu has finally announced that its RV MSX1 helmet has passed European standards testing, and is now available for distribution. It should be homologated for use worldwide in the near future, and if the final price is right, we're sure these guys are onto a real winner.
