I hate reading publications online, but this was slick enough to flip through a few pages. 

Urban Cycling is a book dedicated to addressing the problems of biking in urban areas by suggesting alternatives and solutions to problems. This book was developed as a final student project for a graduate level graphic design program by Katie King Rumford, I “believe that cycling is the future of transportation in San Francisco. It’s efficient, inexpensive, fast, freeing, and fun. Why not ride a bike?”

This is a great read. I recommend that everyone take the time to read this.

Pulled a few stats from the book:

In the United States 40% of trips are 2 miles or less and 90% of those are by car.

If 1,000,000 people replaced a two-mile car trip once a week with a bike ride, CO2 emissions could be reduced by 50,000tons per year.

Driving releases 20 pounds of CO2 pollution per gallon of gas.

25% of CO2 emissions come from motor vehicles

If 1 out of 10 car commuters switched to a bike CO2 emissions would be reduced by 25.4 million tons per year.

The percentage of children who walk or bike to school has dropped from 50% to 15% while shildhood obesity has tripled.

100 bicycles can be produced for the same energy and resources required to build one meduim-sized car.
