If someone wanted to unlock a bike from a bike rack and they didn't have the combination, how could they do it?

It is possible to unlock a bike from a bike rack without the combination if the bike rack has a locking pin. You could look around the bike rack to find the locking pin and then push it in when the bike is in the right position to unlock the bike. If there is no locking pin you could try bending the seat post back and forth to dislodge the lock, although this is less effective. Finally, you could remove the wheel and use the spare key located in the valve stem or contact the owner to get a spare combination.
