If I had to guess I would say that at a moderate effort where you are out of breath, but still able to speak you would be burning 300 calories per hour.
But the only way you could really know this is to wear a heart rate monitor that calculates calories burned.
Get out on the road and ride and you can double whatever you can burn on a gym "bike".
