In addition to being cheaper and cleaner than driving a car, a new study published recently in the British Medical Journal found that bike sharing in urban environments can actually help save lives.

The health impact assessment study evaluated Bicing, a bike-sharing program first established in Barcelona in 2007.

Accounting for the negative affect of air pollution and traffic mortality, as well as the benefit of increased physical activity, the study’s authors found that bike sharing prevented the deaths of at least 12 people each year.
