Visibility being the most important factor when it comes to safe riding at night, L.A.-based Pure Fix Cycles has developed a series of glow-in-the-dark bikes. Each model in the "Glow" series uses a special coating on the frame or wheels, one that glows a bright fluorescent green in the dark. The paint is solar-activated, meaning exposure during daytime reading results in nighttime luminescence. According to the company, "one hour of light equals an hour plus of nighttime fun." Best of all, each model in the series -- made up of the Hotel, Kilo, Micro Kilo and Zulu -- retails at an affordable $399. Find the right bike for you at Pure Fix Cycles' online store.
