I am new owner metro +. 60 or so miles only. Loving it. I have played with the 3 power settings. Eco is fine with me with occasional throttle. I find in Eco, I shift the power assist a bit more, although still only use 1 and 2. The assist seems smoother to me, which I like. After some more miles in Eco, I like it as I work a bit harder, which is the point for me. Throttle is nice at stoplights, in any mode.
