Bike, yo. It was the first one I'd done in a while (I don't do them often, it's a $1100 ticket if the cops see you and you actually stop for them). I was at the balance point and rode the wheelie for probably around ~90 seconds, which on one wheel feels like forever. Angle was most likely similar to this.
Now that I got it out of my system, I probably won't be doing that for a while. Cops down here suck and I've been on the receiving end of their hate against motorcyclists.
