If I remember correctly, the gearing of the Piccolo is 35 to 75 gear-inches, so it's not great for steep hills or fast runs with the wind at your back. The other aspect is that, even with lower gears (mine is re-geared with 27 to 85 gear-inches approx.) it's easier to climb very steep hills with the child walking that with both riders trying to co-ordinate their efforts.

I have used the Piccolo a few times so far with the tandem, and once I got used to it, it rides well, even in the wind. For a more thorough outlook, ask me in a few months, however...
