Lezyne Femto USB C Drive

Compact Visibility.

The Femto USB Drive is housed in a durable, IPX7 waterproof co-molded body that can withstand the worst road spray and rain. Despite its tiny footprint, it delivers 15 lumens of wide-angle red light through its specialized Wide Angle Optics lens, providing over 270° of visibility. Whether you're navigating city traffic at dusk or adding a secondary safety light for a group ride, the Femto ensures you are noticed from multiple angles.

Why the Femto USB Drive is a Safety Essential:

• Wide Angle Optics: The custom-engineered lens spreads light in a wide arc, ensuring you aren't just visible from directly behind, but also to motorists approaching from the sides; a critical feature for intersection safety.

• USB Rechargeable: No more hunting for coin-cell batteries. This updated version features a convenient, weather-sealed charging port, allowing you to top up at your desk or via a power bank.

• Versatile 2-in-1 Mounting: Features an integrated silicone strap that wraps securely around any seatpost (including aero posts) and a built-in clip for attaching the light directly to saddlebags, jerseys, or backpacks.

• Five Output Modes: Choose between solid, flash, or pulse modes to match your environment. With a runtime of up to 15 hours on flash mode, it’s built to last through multiple commutes.

• IPX7 Waterproofing: Built to survive the most grueling conditions. The co-molded construction is completely sealed, making it impervious to heavy rain and the constant spray from your rear tire.

• Minimalist Design: At only 23 grams, it is virtually unnoticeable on the bike until you turn it on. It’s the ideal "emergency" light that stays out of the way until the sun goes down.

The Alegro Perspective: The Femto is the "insurance policy" of the lighting world. We love it because it’s so small there’s no excuse not to have it on your bike. In the shop, we recommend the USB version over the original battery-powered one every time. It’s more sustainable and brighter. It’s the cleanest-looking light you can put on a high-end road bike like the Winspace SLC 3.0 without ruining the aero profile or the weight.
