Not about wristies unfortunately, but a guy at work had his bike pinched a few weeks back (a Jamis Dragon) and today he got a call from the cops saying a bike matching his had been pawned at the Craigieburn cashies and it turned out to be his. I generally don’t have much time for cops, but its worth keeping some sort of proof of purchase and the serial number of your bike and make a police report if it gets stolen. Or you might be wasting your time.
As an aside, the dude at the cashies was kind of a dick about it.
Same thing happened to my old housemate, her tiny MTB tourer was stolen from the tennis last year, someone ‘joy-rode’ it up to Preston (probably ruined their knees), dumped it in an alley, some nice citizen took it to the police and as she had put in a report and had registered her bike she got it back.
