So while walking to and from work in the city where I live, I've already noticed three instances in two months. I'll see a nice mid-range bike with a host of accessories that is locked up only by its frame. The bike will be complete as I walk by the first day and sometimes the second. By the third, either a wheel is gone or the whole bike is stripped down to a carcass. Am I just seeing repeated examples of bike owners being irresponsible, or, has anybody heard of some bike theft scheme where stolen bikes are left for later??? I have a hard time understanding why anybody would leave such nice bikes so long in one place and/or so naked.
