Better buy a lock & chain and also engrave your first name, last initial, & fone # (else driver's license if available) on the underside of the frame that houses the pedaling gears + register it at your local law enforcement facility incl. its serial number (S/N).

It does suck, but they didn’t steal it and the money will be put to good use. Treat it like a fine for not licking up your bike. Lesson learned.

You should have stolen it back. If you can prove it's rightfully yours, there should be no problem. Goodwill won't press charges once they realized they received stolen property.

Why would someone steal your bike just to donate it to Goodwill?

I think your mom did it 😝
