Just curious, why do your "spider senses" make you think it could possibly be stolen?
What kind of bike is it?
Do you have any friends in law enforcement? If you just want to find out if is stolen all they have to do is run the numbers through NCIC.
It's up to you , keep it a mystery or roll the dice. But if for some reason you have an accident or stopped and the Police run the numbers and they find out its hot.
You got a "lot of splandin to do"
Why it may be suspect: The bike was purchased of FB Marketplace from a couple that bought out contents of old storage units, it contained many other bikes.
This bike was expensive new.
Kids/BMX bikes seem to get ripped off more frequently it feels like.
The reg sticker was issued from a pretty wealthy municipality, the bike was purchased by me in its less desirable sister town.
Reasons against it being stolen:
Original reg sticker in place
Very, very bright color was not rattlecanned over
All original parts in place
In reality though, chances are it changed hands at a garage sale or the rich folks simply wheeled it to the curb on a trash day. That’s the most plausible explanation I can think of...
It’s not that I particularly think the bike was stolen, I wanted to look up the previous owner to see if they wanted their childhood bike back but they don’t give two shakes, really.
