Dykes has dropped a level from the Championship to League One to join a Birmingham side, who, having been installed as promotion favourites, have made a good start, taking seven points from their first three games.
“The club has a clear aim for where they want to go in the future,” Dykes told Bluestv.
“They are ambitious and that is like myself as a player.
“I want to get to the top and I am hoping that can be with Birmingham. There are quality players here and it is a top-class club.”
