I've done some searching, but can't find any real answers for this.

What's the actual fuel mileage like for the Chinese HT motors?

The websites say the so called "80cc" motors get 100-150 MPG and the 49cc motors get 200-250 MPG. Is this a realistic expectation? What is the actual fuel mileage for these?

Too many variables. How much you weigh, no. of sprocket teeth, tire size, how much you pedal, altitude, wind, hills, etc...

Just hope your gas tank doesn't leak. But it will. Sorry!

Heavily depends on riding style.

Expect around 80-100mpg start stop urban in my experience. Rider weight wouldnt affect this much as heavy riders would have to pedal more to compensate while lighter riders dont need to.

Expect considerably better for mainly non-stop cruising (probably much better with a smaller sprocket).

When I had my 44t sprocket, I was slightly over 200mpg on a ThatsDax 49CC.

I recently switch to a 36t and Now I'm guessing I'm down to 100 - 125 mpg. I have a few steep hills along my route to and from work. I think that is what is accounting for the drop.

Still waiting for my manifold to come from japan tho. It's been four weeks :(

I have a king's 80, and a leaky intake gasket and exhaust gasket. And I get around 50-60 mpg :( But I am always accelerating pretty hard, (I love when you accelerate and you have that 4-5 seconds where the bike hardly vibrates at all). I weigh 150 lbs and there are no hills where I live.

I've been getting "WAY BETTER THAN A CAR"/mpg. That's all you need to care about. If you are sweating a few mpg's you will stress yourself out about owning one of these.

I get a mile per oz or 128 mpg. My 24 oz tank runs about 24 measured miles. I don't care about it too much as I can afford that. Actually I went over 1000 miles this week on my first build of a motored bike that cost me almost 1000 dollars to build. So with the cost of gas I am at a dollar per mile and can't wait to get to 2000 miles so I can figure 50 cents per mile. After that it's pure profit, right? Sorry I put my Subaru EHO35 in the HT mileage thread.
