A bike can be an instrument change, but we must be the fuel.
Bicycles are a design wonder. They are the most efficient human-powered means of transportation and fill me with joy when I ride. I live in two cities: LA and Amsterdam. There are many differences, but one of the most striking is the mode of transportation. In LA, the percentage of people who bike daily is less than 1 percent. In Amsterdam, over 50 percent of all trips are done by bike.
