To clarify: your definition may be true with motor assisted bicycles, which is one reason why we prefer differentiating between the terms "motor assisted bicycle" (usually reserved for under 1hp or less and/or pedalic only systems) and "motorized bicycle" (general term for a bicycle with any type/size of motor). Deciding that a scooter or motorcycle makes more sense than anything other than a limited "assist" system is a matter of personal preference and not specific definition in this instance.By definition, some pedaling will be inherent with all motor assisted bicycles, being single speeds, at starts, out of corners, on acceleration etc. In a sense, gearing matters more than engine choice and it depends if you want low end torque to easily get up to a modest cruising speed or pedal more at the start to attain a higher top speed. More than that and a scooter or motorcycle starts to make more sense.
I would go for a lower gear. I,am running a 41 tooth. You may want to try a 39 tooth, this will get the bike going quicker at lower speeds.I am kinda on the fence to a 66cc or a 4 stroke. I am a big fella 6'2" and 275 lbs. I know its going to take some snort to get this mass moving. Any thought from the peanut gallery? Besides a diet!!
Thanks for your time

In actuality this isn't relevant to the question at hand
By definition, some pedaling will be inherent with all motor assisted bicycles, being single speeds, at starts, out of corners, on acceleration etc. In a sense, gearing matters more than engine choice and it depends if you want low end torque to easily get up to a modest cruising speed or pedal more at the start to attain a higher top speed.

Yes & I think so lol - as I was attempting to state previously both those engines are quite sufficient, tho given the weight stated I would recommend some manner of gearing to provide both a satisfactory take off as well as a comfortable cruising speedAfter some research I am sorta leaning toward a gt5-sr a super rat? with a internal cdi. They seem to have more top end power, maybe with some gearing and clutch work it would be the ticket to my tubby butt? hehehe
On another note my son pulled his scooter motor, a 49cc yhc(robin?) off his scooter and it has a transmission on it. Would need to change the carb and get the nessary other parts but it should be a descent motoer for a magari falcon gt w/26" wheels....think this is a good start for him??

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....excepting ofc it isn't inherent with a motorized bicycle that it must be a "single speed" in which case a 2hp motor with with an automatic or variator-style transmission would indeed have both "snort to get this mass moving" as well as "a higher top speed" - thus "to expect more from a bicycle with a motor" than simply an "assist" is both practicable & reasonable, without resorting to purchasing a scooter or motorcycle, which I would think if the OP were interested in such - they wouldn't be here.
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.
First off, the linked pdf is out of date by a decade. The MA laws were updated in July 2009 with a third class of two wheeled vehicles added where there had been two.I'm simply attempting to expand on and add clarity in what was offered as a "definition" as it seemed to infer less that what is not only possible, but recommended in this case.
As an example - in your own home state of Massachusetts* a "motorized bicycle" is defined as a pedal bicycle which has a helper motor, or a non-pedal bicycle which has a motor and a displacement of 50cc or less with an automatic transmission, which runs contrary to what you had stated as "inherent". Such would be the importance of inclusive details within proposed definitions.
I'm sorry you feel that it's either confusing or harassment, but a forum is for the discussion of topics in this fashion - up to and including expounding on points made by others as well as the exchange of dissenting opinions *shrug*
