Good points. But the difference between motorcycles and bicycles are that motorcycles have frames designed to work with motors. Bicycles on the other hand we not designed that way.
I believe that if the motor is properly installed on a quality frame thre shouldnt be any issues of stress cracks or metal fatigue.
