Most people can't manage to burn 1000 kcal in a 60 minute workout. I am a large man in fairly good shape and have to put in a pretty hard effort to hit those numbers. People who are smaller or not well trained are going to be significantly lower.
Measuring stationary bike workouts in terms of mph is kind of meaningless. What actually matters is the measured power output based on the resistance setting.
I'm a 40 year old guy who's been sitting behind a desk writing software for two decades. I was in good shape in my 20s but haven't exercised significantly in a very long time.
It took me about three months to get up to that speed, cycling every other day. I started out doing 10 miles, at 10mph.
Three months isn't all that long for an exercise program.
Color me skeptical. In order to burn 1000 kcal in 60 minutes a cyclist would have to sustain a power output of about 280 W. Do you have a calibrated power meter, or are you going by the "vanity" calories displayed by most stationary bikes?
There are certainly plenty of trained cyclists who can maintain that power output, but I've never seen anyone reach that level after only 3 months. If you really did that then you're an extreme genetic outlier with an unusually fast training response.
I don't know, actually. I'll check it out later today. I do know my heart rate is around 150-160 throughout.
I did a lot of cycling in my 20s and while I'm at least a decade out of shape I'm sure I'm relying a lot on past training.

Not that it matters, but reporting mph for a stationary bike (indoor trainer I assume) is meaningless in this context. This could mean that you're cycling anywhere between 0 and 2000 Watts.
I cycle on and off for ~8 years (35yo) and going at 20mph in the real world for an hour or more became possible only after a few years for me.
same here, I'm in my late 20s and was generally unhealthy because of the pandemic, and I burn 630-700 calories per 30 minutes worked out
That is unlikely. How are you measuring calorie burn? You're probably overestimating.
As a point of comparison, an average size man would have to run at a speed of at least 11 mph (18 km/h) in order to burn that many calories in 30 minutes. Not impossible, but well beyond what most of us can manage.
