There has been speculation about the striker's future since he revealed ahead of Wales' match against Luxembourg last week he was not going to be included in City's 25-man Premier League squad.
Top-flight clubs in England and Scotland were lining up to sign Bellamy but it was confirmed he will drop down to the npower Championship with his home-town club on a season-long loan.
Bellamy said: "Nothing's difficult about this. I had the greatest time at Manchester City at a great period in their history.
"I was bought to take the club on to the next stage and I feel I played a big part in doing that. The players they're signing are incredible.
"The next couple of years I'm sure they'll get the Premier League title, and I hope they do."
