One of the profound economic implications of bicycle use is that it liberates the user from [[motor fuel]] consumption. (Ballantine, 1972) The bicycle is an inexpensive, fast, healthy and environmentally friendly mode of transport. [[Ivan Illich]] stated that bicycle use extended the usable physical environment for people, while alternatives such as cars and motorways degraded and confined people's environment and mobility.<ref>Illich, I. (1974). ''Energy and equity''. New York, Harper & Row.</ref> Currently, two billion bicycles are in use around the world. Children, students, professionals, laborers, civil servants and seniors are pedaling around their communities. They all experience the freedom and the natural opportunity for exercise that the bicycle easily provides. Bicycle also has lowest carbon intensity of travel.<ref>[http://blogs.worldbank.org/publicsphere/global-cyclists-say-no-carbon-opt-cdm "Global cyclists say NO to carbon – opt for CDM"] {{Webarchive|url=https://web.archive.org/web/20171004035739/http://blogs.worldbank.org/publicsphere/global-cyclists-say-no-carbon-opt-cdm |date=4 October 2017 }}, The World Bank, 27 October 2015</ref>
