Abandoned bikes

There's a bike outside my office, a step-through girls Peugeot; no front wheel, brakes hanging off, no lock - is it fair game?

What do you lot think?

Would be good for the missus after a spray and with my old front wheel.

take it. give it a new life.

What if the bike is clearly abandoned (rear wheel gone, stays twisted, chain orange with rust), but it's firmly locked to a railing on a pavement? What are the ethics of removing the nice vintage lugged top bolt stem from it? (rest of the bike is shite).

take it , give it a new life.
