learning to trackstand for the first time is best done in the middle of a doorway so you can balance with your hands on the frame and dont need to keep dismounting...
for easiest track stands, keep your wheel turned a considerabley large amount to the right or left... right if you are right handed, etc (from my experience)... i can lead with left and right feet, but i can't for the life of me balance with my wheel turned to the left.....
