Well, I am not actually set on three.

Here's what I want to do.

I want to get this bike: http://www.bikesdirect.com/products/dawes/deadeye.htm

And perhaps put something like this on it: http://www.amazon.com/Shimano-Nexus-...6112738&sr=8-3

The truth is I don't know how to take a single speed and put gears on it.

I'm not intense, but I'd like some hill climbing ability.

Just some thoughts in my head.
