The 12 largest bicycle sharing systems in Europe offer health and economic benefits. Currently, the use of shared bicycles by people who previously used their cars avoids 5 deaths and saves 18 million euros per year. If all public bicycle trips were made by previous car users, 73 deaths and 226 million euros would be saved every year. These are the conclusions of a new study by the Barcelona Institute for Global Health (ISGlobal), an institution supported by the “la Caixa” Foundation.
