Making a Segway clone and need component selection guidance

Greetings everyone: I have been doing exhaustive internet reading about everyone's Segway vehicles and the electronics there-in. My biggest concern is to keep this simple, but everyone seems to be using a different board.

I have mentally selected a Leonardo for my main board, but my question is this:

I will be using an accelerometer board, a gyro board and two motor driver boards. Will the Leo be up to this in pinout,CPU speed & capacity?

Or do you have a recommendation, as I am new to the "Duino"

Thx, Miz
