There aren't really any modes. There are 5 different tension settings, that's it. 1 being no tension, 2 and up getting harder and harder. I suggest you never go past setting 2. Simply hold the button down to scroll through the flashes. It's the same as the stock vlocity board only instead of 8 there are 5 settings.
