icycles are the ultimate clean air, zero emissions vehicle. Bikes are practical, economical, low-maintenance, and non-polluting. Cycling is a fast and practical way to get around town. Plus, riding a bike is fun and a great form of exercise.
Bikes are a very environmentally friendly means of transportation - no tailpipe emissions, no evaporative emissions, no emissions from gasoline pumping or oil refining, and zero carbon dioxide or other greenhouse gases that contribute to global warming. Bicycling also means less water pollution (many people don't realize that motor vehicles are a significant source of water pollution as well as air pollution). And, bikes are quiet, so they don't contribute to noise pollution.
