With the stolen bike, if the vanmoofs are stealthy enough to no get caught in the act, it might go pretty fine as I assume the thieves won't file police reports. Now if they already sold it, things might get hairy... in my place when your car gets stolen and you file a report you need to provide all kind of documents which a stolen bike owner won't possibly have. So I guess approaching the same way for theft of expensive gear (need to provide ownership proof) could curb it a little. And yes, I know also cars get stolen.
