I know of two freewheel hubs:
Staton:
http://www.staton-inc.com/Details.asp?ProductID=2770
and bicycle-engines.com:
http://www.bicycle-engines.com/freewheel-sprocket-axle-wbrake-p-297.html
Can anyone confirm that these are both freewheel in the sense that the motor driven sprocket can be held still while the wheel turns?
I believe we have already gotten confirmation of this on the Staton.
Anyone know of any other freewheel sprockets?

So I guess Staton does meet the criteria, I own a Staton friction drive but not a chain drive.
I also have this hub: http://www.bicycle-engines.com/freewheel-sprocket-axle-wbrake-p-297.html
So my Titan should perform like the Staton when I get it on.

The question is a good one and one that has occupied some of us for a long time.
Staton has become a standard and worked out a lot of the bugs so while I certainly give him his due I'm one who is always looking to improvise and simplify......as in less weight.
I guess I'm in the narrow category of MBers whose primary interest is first retaining all the functionality of the original bicycle and only looking for a bit of power assist over accommodations made to motorize it. I've spent a lot of time building up bikes with quality components and really dislike, for example, the idea of having to replace a quality crankset in favor of some one piece affair to accommodate mounting a motor.
It's a good discussion, one that I appreciate and I continue to wrack my brain and be on the lookout for solutions that meet my needs.

Our freewheel's are what your looking for you can use your bike like normal and your chain will not move, However there intended for the four stroke kits. I say this because the 4's are pull start, In order to use our freewheel hub you need to have a GGG (Give gas go) happy time with a pull start on it but we do offer a solid but again that's not the topic of discussion. So I guess if you have a pull start the answer is yes otherwise if its a pop start then no its physics. But I have seen a quick disconnect from some engineer in Australia.

I have one of your freewheels w/48T sprocket. The freewheel is rather large, and is very nice that it unbolts from the sprocket. However, if the freewheel breaks, are new ones availiable? I didn't see replacement freewheels for sale on the bicycle-engines website.
My 48T freewheel did NOT fit the Staton plastic wheel as the thread & hub sizes were slightly different by a fraction of an inch, so instead I'm inserting a steel 5/8" axle hub into the freewheel and will weld the hub to the freewheel, so the 48T freewheel will work on a 5/8" jackshaft instead. Then a solid sprocket is used on the wheel and I will still have freewheeling. Problem solved.
My biggest concern is your sprocket freewheel, it appears to be stronger and larger than the Staton 16T freewheel, so I want to stay with it, I'm just concerned that if it breaks, I'll be able to get another one, and not have to switch to different parts. The goal is a powerful DIY 4-stroke freewheeling bicycle that WILL NOT break down by minimizing all the possible weak links.
What would be a really good is if bicycle-engines offered an alternative plastic wheel custom machined for the freewheeling sprocket, as some of us do not want to mess with spokes anymore.

I do, and it's awesome. Wouldn't have it any other way.
I cheated, tho... bought it from here, but they don't sell the whole bike anymore (maybe call and ask?). They do sell the larger, non-folding version, tho... here. The freewheel assembly does look pretty similar to the bicycle-engines.com link above, tho mine doesn't have those grease nipples (and I don't understand where that part goes anyway). I asked the owner of Five Flags about changing sprockets, and he told me I'd have to make my own, but it should just bolt up if you have the money and/or the machining skills... mostly just the will to see it thru.
There's no derailers on my bike... I just pedal or hit the thumb throttle lever. Too easy. I ride with one hand quite often [but slowly]. I burn the brake pads up coasting down a drawbridge near me so quickly. Not freewheel related, but I can also fold my bike up and put it in any car/truck/SUV. Took it in the backseat of a Honda Civic when visiting a friend in South Carolina a couple months back. The short frame also provides plenty of "nut room" so I never have to squash 'em when "climbing" up curbs. Everybody should have a bike this versatile.
Pretty sure the guy at Five Flags could get you either the 20" or 26" wheel. My pedal freewheel was kinda problematic, so I switched it out for a few bucks, and everything's great now. Only crappy part about the bike is the squeaky folding handlebars, but it gets the job done for sure, and it did support a 160lbs person when I first got it. That was when I was a young MB lad, tho. I'm much wiser to MB etiquette nowadays.

a pretty nice all around looking MB
oh yes -- I have seen that motorized bicycle before
seems to be a pretty nice all around looking MB
that little fold up model one you got -- sweet little thing
I need to be careful before making any phone calls regarding MB's
I am in the mood for #2 for sure
but waiting at this time so as to see a little more regarding the new to be MB motor thing
always having fun on those things

Just bumping this thread, as it really meets a lot of what my other discussion was about, with a steath engine system.
The Stanton friction drive looks like the perfect engine stealth system. I can make a pack cover that will fit over the engine so that nothing is exposed.

Will need to look at why you want a freewheeling hub and a chain drive. Guess you want some lower center of gravity, and a way to customize other ways. Need to re-read this discussion again.

I disagree, I bought one and you cannot spin a typical Shimano gear cluster onto the right side, I spun a single speed BMX freewheel on it though and it worked fine. So thats not what Im looking for, Im out $50 + shipping that I can maybe recoup here in "Buy/Sell".
Not blaming you its the price I pay for experimentation but just want others to learn from my mistakes.
For the guys who think friction drive fits the bill it does not. Not only the usual drawbacks of friction (like poor traction) but it does not freewheel it still is connected to your engine and will turn when you wheel turns unless your centri-clutch disengages. So unless you have a freewheeling friction roller....
Which BTW is there a freewheeling roller out there?
