It’s no secret that just about anywhere you go in the Netherlands is an incredible place to bicycle. And in Groningen, a northern city with a population of 190,000 and a bike mode share of 50 percent, the cycling is as comfortable as in any city on Earth. The sheer number of people riding at any one time will astound you, as will the absence of automobiles in the city center, where cars seem extinct. It is remarkable just how quiet the city is. People go about their business running errands by bike, going to work by bike, and even holding hands by bike.
