Recently, I've had a couple less than optimal dismounts. Mainly when I take my front foot off and the board rears back. Side note: having a fender for this alone has preserved my inside ankle.
I've read the dismounting posts and finally learned how to roll the toe off and that is my go to now so no more problems. But, for anyone that doesn't have it down yet, there is another option.
Come to your stopping point and speed, squat down a bit and hit the power button. The board will likely tilt frontside and dismount. Super easy and a nice engagment of the quads.
