Full Beam Fusion SpeedLED£499.99

Speed-sensitive light system

BikeRadar score4/5

Full Beam’s revolutionary light (361g) isn’t totally polished but it’s a brilliant no-brainer unit for flat-out technical riding.

By linking the light to a cycle computer style sensor and magnet, the faster you go the brighter the light shines – up to an insanely bright 3,000-lumen maximum. 

It automatically punches ahead when you’re blasting, but reduces glare on slower or techy sections. This lets you concentrate on riding and maximises the already decent battery life (two hours five minutes).

The speed steps, fade length and brightness are all custom tunable, and you can also run it as a conventional integrated light. The metal clamp is awkward to adjust, the battery runs out abruptly and a cordless sensor would be much neater, but the overall concept still makes it one of our favourites.

Guy started filling his brain with cycle stats and steaming up bike shop windows back in 1980. He worked the other side of those windows from '89 while getting a degree in “describing broken things covered in mud" (archaeology). Dug historical holes in the ground through the early '90s, then became a pro bike tester in '97. Guy has ridden thousands of bikes and even more components the world over since then and can remember them all in vivid, haunting detail. Can't remember where the car keys are, though.
