In a 2 second scene from the movie Project A Chan clamps himself onto the sides of a wall and lifts the cycle (that he was on) and swings it at an oncoming attacker. Now if you watch the video scene carefully you will see that he is trying to get some grip with his left foot on the wall (whereas his right foot is placed on a windowsill which cannot be seen in the angle shown below. It is a pretty tough stance if you think about it. And his timing of the swing is impeccable. The other guy falls flat down and his cycle does a full 360 degree flip to the other end of the frame.
