Her ride, with its custom titanium frame painted like a pair of blue and brown argyle socks, became one of 824 reported stolen bikes in Seattle that year, according to city data (by 2013 the number rose to an annual 1,121, three per day on average). Had police given it to her straight, Rosa would have learned that only 1 percent of stolen bikes make it back to their owners. And thieves rarely get caught in the act. Someone leaning over a bike to unlock it looks pretty much the same to passersby as someone leaning over a bike to hack or cut its lock. And as Rosa now realized, inside storage isn’t necessarily better.
