Have about 8 miles so far, running pretty good. Couple of minor boogaboos upon delivery, the front brake cable was missing the tip and a little frayed, and the folding handlebar tube was scratched (easy fix with a sharpie). This is my first e bike (I've owned large streetbikes, scooters etc.). These are definitely fun technology, on pedal assist you get some cardio without killing yourself. I'm getting used of power management and I think I will get some good miles per charge out of it as well. I love the black, reminds me of a Sportster I bought brand new in the 80's.
