350W geared front hub, 36V 11Ah bottle battery. Hand throttle only, typically at full and level 5 assist (except in cases where I want less assist, which is why I wanted the control of a hand throttle . . . things like riding on ice). I have no idea how it would perform without pedaling, as I always pedal. It isn't a motorcycle, I don't ride it like one.
Normal flats the speed is typically between 17-20mph (wind decreases this to about 12mph). I have never really pushed the range on the battery, I would safely say about 15 miles, top. However, when it is below freezing the range drops fast.
