The E-V Sunny Solar Bicycle has solar panels built into the wheels, which maintain a constant charge to the batteries. When you don't feel like pedaling the bike is powered by a 500 watt front hub motor. It'll get you up to about 18 mph, and even faster if you fall off a cliff. The catch is that it weighs 75 lbs., so you're gonna need to use that motor unless you have legs like mighty oaks. A new one costs $1295, and kits to solarize your own bike start at $795. I remember the first time I got on a bike and realized that you have to pedal them to go. What a letdown that was. I thought they were silent motorcycles for people who weren't into wearing leather.
