Was attempting to go off a ledge and land on a drop ramp, when I got into the air my feet came off the pedals. Once I landed my butt hit the saddle causing it to point up which caused my scrotum to cling on for dear life as the rest of my body tried to fall off. Still technically on the bike, I ran into a tree. Got checked out and had (after finishing my ride of course): a torn scrotum, swollen balls, gash from pedal in my lower left calf, bruised crotch and groins, right brow was cut, and a bruised shoulder..Bought clip pedals later that same day.
