Bicycle left outside for over a year. Possible to save? Two years ago I was knocked off my bicycle by a car and was too scared to cycle for a long time, and left my bicycle outside uncovered for over a year. That was a mistake.

Now, WD-40 applied to the chain did not help much. The chain still won't bend. I think cleaning it won't be possible, I will replace it. But how about the rest? I have no idea what I will have to do to make it work or if it is even possible. Do I have to replace anything else apart from chain and cables?

These are the bicycle specs.
You don't have pictures of the bike, but honestly, theres not much you need to worry about. Pump up the tires and make sure they hold air. Check that the brakes work (may need new pads, cables). Add a new chain and you're likely good to go. 

A lot of bikes live outside their whole lives (in rain and snow) and aren't worse for the wear.
