Of the reviewed models the Cateye and Knog, unfortunately, had to retire early due to their weight and the high center of gravity on the helmet. The helmet lamps from SIGMA and Magicshine went head-to-head for the buyer’s choice. In the end, the MJ-906 model from Magicshine was in the lead, as it is cheaper by € 20, and in addition to a supplied taillight also has the better luminous range. Once again, however, the Lupine is far superior to the rest of them. The low weight, even illumination, high quality of workmanship, and also the innovative fastening system as well as the wide range of applications make the Lupine Piko 4 R SC our editor’s choice!
