The tiny twin-LED Piko packs an impressive punch and advanced control tech, if you can afford it and don’t need epic run times. As it’s designed primarily for helmet use, the 1,800-lumen output is focused tightly for high-definition longdistance vision that works great at high speeds. Minimal weight means no neck strain issues, and the 120cm lead allows easy pocket placement. The sealed hardshell battery includes an LED run time display that doubles as a back-up rear light. Lupine’s Bluetooth remote lets you change modes from the bar. Power output and menus can be changed manually or via a smartphone app, which helps eke out the short full-power run times. Apart from an occasional need to reset modes, our long-term Pikos have been bombproof in heavy use, helping to offset the high price. Weight 199g Run time 1hr 20mins Price $472
