Motivate: The number of bike-sharing programs worldwide has doubled since 2014 - and the number of public bikes has increased almost 20-fold

On Monday, Lyft announced its acquisition of bike-sharing company Motivate, which is responsible for operating a number of popular shared-bike systems like New York City's Citi Bike and San Francisco's GoBike.In fact, Lyft says Motivate is responsible for 80% of the trips on shared bikes in the US, which would give it a significant competitive advantage over Uber and its newly acquired bike-sharing company Jump. But Lyft's share is still a small piece of a very large pie.Cities have increasingly been using bikes and bike-sharing programs to fight pollution.
