Twenty-eight grams disappears on a handlebar. The Lezyne Femto USB C Drive Front Light weighs about the same as a few coins, which means it can stay mounted permanently without affecting bike weight in any meaningful way. For riders who want always-on visibility insurance without committing handlebar real estate to a chunky light, this fills the role. The silicone rubber strap wraps around bars in seconds and holds position without tools or adapters, accommodating various bar diameters from road drops to flat bars without shims or spacers.

Wide Angle Optics spread the 50-lumen output across 270 degrees, addressing side visibility at intersections where perpendicular traffic poses the biggest threat. The Daytime Flash mode pulses at full output to cut through ambient light when steady beams get lost in the visual clutter of traffic. This isn't a light designed to illuminate dark trails or unlit roads. It's a visibility aid that signals your presence to drivers and other road users. Six total modes split between solid and flash patterns, letting you match output to conditions. The Femto mode drops to minimal draw and stretches runtime to 15 hours for situations where you just need some presence on the road.

Co-molded construction keeps the housing lightweight while meeting IPX7 waterproof standards. That rating means temporary submersion won't damage the electronics, not just rain resistance. Commuters who ride through all weather conditions won't need to worry about moisture getting into the housing. The USB-C charging port hides behind a threaded Composite Matrix cover that seals out water and debris, so the connection stays clean even after wet rides. No proprietary cables to track down when battery runs low, and USB-C means faster charging than older Micro USB standards.... Read More
