I have always had naturally good balance, I could walk on my hands when I was like 15. While I can track stand on a fixie for several minutes. I cannot really stay completely stagnant for more than 10 or 15 seconds without inching forward on a freewheel bike. I generally stay clipped in if I know the light will turn in less than 30 seconds when Im at an intersection. I enjoy being faster than cars at a green light and staying clipped in is the only way.
