I saw someone yesterday with a big wheel who I was sure was about to bail. He was unicycling down a pretty steep street. He managed to make it down the street and turn the corner, but it looked like a real struggle.

I know from riding a fixie that for streets that aren't too steep it's not hard, you just have to effectively "pedal backwards", allowing slowing the pedals down as they come up behind you. But, I don't know what a unicyclist can do on a very steep street. What I would do on a fixie doesn't work because it requires small skid-stops, which means you need a front wheel.

What would you do on a steep hill? I assume that by the time you realize it's too steep you're already going pretty fast, so just bailing would be difficult.
