The bicycle is en vogue.
Over the past decade, an increasing number of cities around the world have adopted bike-sharing systems — the setup that allows urban dwellers to share bicycles for short-term amounts of time for a fee (think Citi Bike in New York City or Santander Cycles in London).
According to a recent blog post from leading bike-sharing consultancy MetroBike, 855 cities across the globe had bike-sharing systems in 2014. That's compared to 703 one year earlier in 2013, and only 11 cities a decade earlier in 2004.
