After months of experimentation, Pure Fix Cycles just unleashed Kilo, a glow in the dark frame as part of the finally perfected GLOW series. Claiming the title of the very first glow-in-the-dark bicycle, it features paint that requires just an hour of sunlight to activate. In the daylight, the frame is a bright yellow while at night it glows like the florescent green pictured above. The highly reflective paint comes on either the frame, wheels or both. Seems fun, safe, and could be a big hit with aging ravers.
