The five output modes offer up to 15 lumens and the custom optics lens offers well over 180 ° visibility. The Femto USB Rear can run for up to 15 hours and is easily rechargeable with the included micro USB cable. A secure, threaded composite matrix cover keeps the USB port clean and sealed. The Femto USB is perfect for serious cyclists looking for a simple and inexpensive way to add visibility. Also available as a pair.
