I had no intention of riding in "zone 3" where I would be breathing so hard I would be unable to talk. At the seven mile mark I switched to 15th gear and the watt meter went from reading around 170 to about 190 or 200 for the same pedal cadence between 80 and 90 rpm. I tried to keep the rpm in the lower 80s to make things easier on myself, I was sweating about the same as if it was a real ride on a warm day, and the pedal resistance and rpm was about the same as I was used to on the hundreds of rides of a similar length I had taken on my road bikes.

Try again.........or not.

"Feel" is completely different between indoor and outdoor aerobic activity of this sort. Sweat in particular is a terrible basis for comparison because indoors doesn't offer the same pervasive evaporation that riding through the air outdoors does. You're not metering your watts outside, neither do I. But I wouldn't be deluded enough to think I can estimate whether they are "about the same" as my wattage on an indoor machine.

Comparing mileage is a pretty silly basis for review as the one thing a trainer definitely is not doing is covering ANY distance. I only use such numbers on an indoor machine to compare the intensity of a number of workouts on the same machine. If you want to compare it to the intensity of your outdoor ride, you'd need to be measuring your outdoor wattage. Otherwise, your comparison is utterly meaningless. No one is surprised that spin bikes assume a highly flattering MPH figure as it's really arbitrary as to what kind of riding is actually being simulated. For all I know, they're assuming a 20 mph tail wind.

The actual bikes looked just like the stock photo. I don't use "cell" phones so do/can not snap a thousand photos of my life everyday like most are doing the last decade or so when they became popular. I have a Nikon digital camera I got at an estate-sale for five-bucks but I don't carry it around that often. Maybe I will remember to take it with me next week if I test a different spin bike to see how it's calibration compares with the first one I tried.
