This is old news for most Europeans cities. We've had it in Valencia for almost 2 years. The old saying "the greatest thing since sliced bread" will soon be replaced with "the greatest thing since bike sharing." It is what urban planners call "transformational" meaning it will change an entire city's attitude about public transportation. I have two bikes but I still use our system every day. I am shockingly lazy when it comes to walking and will avoid laughably short trips on foot in favor or taking one of these cool bikes. I pay 18€ per year.
