There a few things you need to consider, your age, size, weight and what type of riding you will be doing. These bikes are fine for a beginner that does not get too crazy. If you are more advanced, you might want to wait until you can add a little more money to it and go up a model or 2.
That said, we sell the 2hip and the Stolen in our shop. The Stolen sure does look sweet in either of the 2 colors. As far as quality, they are both about the same, good but not great. The 2hip might have a little advantage. You get what you pay for.
I can't say anything about the WTP. I had considered selling them too. Most of them are pretty expensive and I haveto buy 6 to get started, so for now I have decided not to carry them. They are great bikes, but this one being a low end model, again, might not be the best for you.
It will all come down to what riding you will do. If you just ride around town and do basic stuff you will be fine with any of them.
