Here is a cool bike that glows in the dark, allowing you to have fun with it at night. The Zulu bike is painted with solar-activated paint, so an hour of daytime sun gives you over an hour of glow at night. The bike features a flip-flop rear hub, track-inspired frame, and 700×28 tires. These bikes are made of steel and weigh between 21 and 25 pounds depending on the size you go with.
