And with the Upton Park outfit then opting not to offer him a new deal, Bowyer made the move permanent in the summer.
Having played a key role in helping Alex McLeish's side secure their top-flight status last term, the former Leeds man is now enjoying the challenge of helping them remain in the Premier League.
He scored the only goal of the game against Fulham on Saturday to lift Blues to 13th in the table, four points above the relegation places.
Bowyer said: "I just like playing and enjoying my football. Days like this make waking up on Sunday mornings worthwhile.
"I wouldn't say I took a gamble coming here. All I wanted to do was to get playing football again. For one reason or another, they didn't want to extend my contract at West Ham and I came here.
"It's turned out to be a good move for all parties.
"A few players might have been happy merely to pick up their money. It would have been easy to do it because London is my home.
"But I didn't want to be sitting watching football. I'll be doing that when I finish playing. You have to play as much as you possibly can while you can."
