It’s interesting because in my 5 years in the Netherlands, the general opinion was the opposite of this: bike theft is such a common occurrence because everyone rides the same, probably stolen and resold, black bike that you should ride a new, design bike that stands out, like a VanMoof–because no thief would be dumb enough to go for it since it would be obvious where you got it (and more importantly, almost certainly registered/traceable vs an old clunker).
