Check the brakes make sure the pads haven't been worn out. Make sure the chain looks greased. Make sure the front fork is tight with no play. As well as pedal component. Make sure it switches to all gears (although adjusting that is pretty easy).

Mine was in great working condition and had been ridden quite a bit. The tires on mine will need to be replaced it is easy to tell they show a lot of wear.
