Impressively tuneable, usefully powerful, minimalist helmet light, but very expensive

This review is a small part of our Best Mountain Bike Lights feature, where we tell you the three best lights – plus eight others to consider – after testing 24 different sets of lights.


Lupine’s tiny Piko helmet light is light and feature loaded but it’s heavy on the wallet as a result.

The tiny twin LED head delivers a focused 1200 lumen beam for good distance detail. There’s little peripheral coverage as the Piko is primarily designed for helmet use (the same price Piko TL is the self-contained bar version). That means it comes with a neat pivoting cradle mount for helmets as well as a bar mount but 3M stick-on and GoPro-style mounts are available to make the most of its tiny size.

It comes with a wide spaced three power output as the default setting, but you can tune the light levels to anywhere between the 1200 lumen max and 100 lumen minimum – even the on/off sequence is programmable. Even at full power run times are pretty good considering the tiny indicator strip equipped SmartCore battery.


Rectangular deep cuff connectors keep the leads well sealed and the Piko family has the best reliability reputation of the Lupine family, with no headunit or battery issues on ones we’ve tested over the years. Price is high compared with similar units such as the Gemini Duo.
