Does anybody know how many calories you burn on a stationary bike?

I just need an aproximate guess if you were just going leisurely for an hour.

 

The CC estimate isn't helping me.

 

Thank you~

windandwaves1997: Since spinning is one of my primary forms of exercising, I have checked many Net calulators, plus I have checked my Airdyne Evolution's read out, and I have checked my Polar read-out.  There has been a wide range of guestimations from all those sources. The important thing is to know your weight.  A 240 pound person is burning more calories than a 115 pound person, if both are spinning at the same rate. Ok, to take a guestimated average from several calculators, I record that I burn 360 calories for 1 hour spinning.  I weigh 170-174 pounds.  And I spin "moderately." However, most calculators give me more credit for calories burned than that. I would guestimate 400 calories per hour for you; but that is, indeed, a guestimation.
