That is not irony, it's just bad math. Fuel mileage is calculated by the simple formula
(Miles traveled)/(gallons used)
which, for a bicycle which has traveled, say, 10 miles is
(10mi)/(0gal)
The problem here is that any number divided by zero is undefined. Ie it is not possible to divide something by nothing.
(Xmi)/(0gal) is not a derivative. The variable x is the mileage, and it is not approaching zero (think of a vector) and will never be anywhere near what could be construed as infinity; the fuel consumed is always zero. In other words, the graph is linear and not an asymptotic function, the plots only move in one direction from a singular point of origin 0,0.

Saying the mpg is infinity is perfectly reasonable because the limit as the gas consumed goes to zero is indeed described as infinity. Depends on how careful you want to be about your limit being a real number. See https://en.wikipedia.org/wiki/Limit_...nfinite_limits

Livestrong claims it's closer to 50 calories to pedal a bike a mile at over 15 mph. I suspect it's less, but lets pick a number and say it's 30 calories per mile. How much money is that? Gotta be at least 10 cents....which is about what my car needs in gas.
lol...pedaling a bike and driving a car is a wash, dollar per mile, energy wise.

I tried Googling it and actually found what appeared to be a site for the manufacturer. However, when I get to the page linked to a "Get your Zero Per Gallon decal here," I get a notice reading "Site Suspended."
Maybe so many drivers were offended by this that they all got together and formed a coalition to stop it.
I think it's a cool idea, even though anybody with too much time on their hands can poke a million holes in it. My bike is full of tourist decals. I'd like to add one of these to the mix.

There's a pretty good article that discusses energy consumption of cars vs bikes. Considering where most of us get our food and current agricultural practices, cyclists get the equivalent of 70 to 130 mpg.
Lard has about 2000 calories per dollar. You could ride all day for a buck or two. Let's see a car do that.
Of course, many (most?) Americans consume far more calories than they need so the fuel cost of cycling is essentially zero for things like going to work unless it's a long distance. Imagine a car that had a gas tank that constantly expanded. That's us. Yikes...

Well, you don't quit burning calories just because you drive. Sitting burns about 75 calories per hour. Reading about 100. Driving is probably somewhere in between. Depends on your muscle mass too.
There's a pretty good article that discusses energy consumption of cars vs bikes. Considering where most of us get our food and current agricultural practices, cyclists get the equivalent of 70 to 130 mpg.

Of course, I suspect, most of us eat that anyway.

Sure. But, if someone were to ride a bike everyday for fifty miles, which is my round trip commute, then they would need at least 1500 additional calories per day to do it. I'm guessing here, but I would say that's two good size burgers and an order of fries which is at least $10 worth of food. Of course, I suspect, most of us eat that anyway.
I have found that commuting in the morning and evening really ramps up the calorie burn through out the day. I am usually always hungry.

The OP claims he's just trying to say how much he's enjoying life. I'm just pointing out that others may perceive his message differently than intended. That's not nit picking, it's pointing out something he may not have thought of.
