Lezyne's Micro Drive LED steps it up a bit from the Femto Drive. Lezyne's MOR Optics technology shapes the 70 lumens emitted from the single LED bulb into a bright beacon of visibility. Your visibility to other motorists is increased by Side Visibility Cuts—two half-moon cutouts on either side of the lens—which allow the bright red light to be seen from the sides also.
Design and construction are typical Lezyne, elegant and robust. The Micro Drive body is CNC machined aluminum for resilience and style, plus it helps to dissipate heat build-up from the operation of the light. An integrated USB charging stick is hidden behind the composite matrix end cap, so you can stick the Micro Drive right into your computer or run a cable to recharge it. You'll know when it's time to replenish the Li-ion battery thanks to the fuel indicator, located in the top-mounted power button. A stand-alone, cradle-style mount attaches to your bikes seatpost and is angled slightly up so the light points straight back.
