Although it lacks wireless functionality, it features a battery capacity indicator. The Piko has been completely redesigned and is simply better in every aspect. It is more powerful and shines incredibly efficiently thanks to its newly developed optics. Both the edge illumination and the range have been significantly improved. Here it is - a new generation of Piko that is better by all standards. With our specially developed FastClick system, you can carry the battery of the Piko X4 and Piko XDuo headlamps directly on your head and swap it out for another in just a few seconds. The capacity indicator with integrated rear light function of the Lupine SmartCore batteries not only enhances your safety but also ensures you look great from behind.
