More than that and a scooter or motorcycle starts to make more sense.

Minor points to be sure, but there are some inherently critical differences between the rudimentary single speed motor assist that you described "by definition" and the potential that exists within the general classification of motorized bicycle & in fact given the interest stated, including the title and the physics involved - I thought it prudent to mention that indeed more can be expected as well as achieved, thus the second half of my post.
I see the confusion persists. Either that or a pattern of harassment is beginning to take shape here. Read my post which I have already included several times in subsequent replies. You might notice the words definition and bicycles are both in italics used to imply a connection. You might also see that the comment 'being single speeds' is one in a list of several physical obstacles that one encounters overcoming inertia. I further address that by then talking about gearing, etc. to attain what one is looking for in performance. Why the continued insistence on parsing my comments with a fine tooth comb to suggest they mean something other than they do I am at a loss for.
