The Lezyne Micro Drive Rear is designed to be all you need in a rear light. A standard mode with 30 lumens output & a daytime mode with a flash of 70 lumens ensures youll be noticed at all times. Compact & lightweight design & angled mount means it will fit around any seat tube without the need for tools & point directly backwards, not downward to your rear tyre. CNC manufactured from aluminium, the Micro Drive is water resistant & the cuts in the side of the design means it can be seen at up to 180 degrees. Lezynes MOR Optics means that it has a uniform & clear spread of the Micro Drives lumens behind the rider. The USB (Universal Serial Bus) charger & Intelligent Power Indicator mean that if you get to your destination & you see your light is low on power, you have the charger with you. These features make it the ideal commuter light as almost all destinations have a USB (Universal Serial Bus) capable device to plug it in to, & itll charge from flat in just 3 hours.
