Reevu has improved their MSX1 helmet and at least one of them has landed in a reviewer’s hands, or head. The helmet uses a mechanical mechanism instead of rear-view cameras. According to webBikeworld, it functions just like a car’s rear-view mirror, with the small mirror in front resting just outside the rider’s line of sight.
They also say that the helmet is “built like a tank,”. The rear-view system is just icing on the cake of an otherwise already superb helmet. Needless to say, this could save some lives.
