Most PS2-era football games lack a dedicated "bicycle kick" button, but you can simulate acrobatic volleys with timing and positioning.
Methods to Try
Lob/Chip Button + Timing: In many titles, a well-timed lob pass/cross combined with a shooting input as the ball arrives can trigger a volley that resembles a bicycle or scissor kick.
Specific Button Combos: Check the game's control guide (in manual or pause menu) or search online for "[Game Title] bicycle kick controls PS2".
Trick Shot / Special Move Modes: Some games (e.g., FIFA Street series, certain Winning Eleven versions) have dedicated "Trick Shot" or "Special" buttons for acrobatic finishes.
Game-Specific Notes
FIFA Series (PS2): No dedicated bicycle kick button. Simulate with lob + shoot timing near goal.
Winning Eleven / Pro Evolution Soccer: Often have specific input combinations for acrobatic aerials (e.g., R1 + Shoot + Direction).
Tips
Practice in training mode / free kick scenarios.
Position your player near the penalty spot with the ball coming from a cross or high pass.
Timing is critical—press shoot just as the ball reaches chest/head height.
Controls vary significantly by title—consult the manual or experiment in practice mode.
