BTW, that frame looks great to motorize, I bet the engine will drop right in.
A flip-flop hub lets you take the rear wheel out, flip it over, mount the sprocket on the other side, put the wheel back in, and turn a fixie in a freewheel.
A fixie without a flip-flop means that, if your pedals turn, your wheels turn - and vice versa. A motorized fixie without a flip-flop is a high-speed, heel slapping, eggbeater of a contraption.
