The new "owner" will keep the bike as he has bought it in good faith.
The shop will claim that it cannot check every used bike.
The rightful owner could try to get money from the person who stole it (if found), but they most likely don't have any money.
It's the perfect crime and the reason why we cannot have nice bikes. People are literally sleeping with their expensive bikes in a room.
I can't believe the law works like that. Are you telling me that if I buy a yacht in Austria "in good faith" from someone who doesn't own it, I can just sail away on the yacht, original owner be damned?
However as soon as you as the buyer feel something is off, you aren't protected anymore because only good faith buyers are protected. For example if you go to the black market or something seems to be extremely cheap you definitively aren't protected anymore.
It's a conflict of interests. This law is trying to do a tradeoff. Imagine you went to Walmart and bought a bike and everything seemed fine but it turned out that an employee stole the bike and sold it to you in the name of Walmart. In this case you can keep the bike.
