how many calories burn bicycling for leisure

I am curious about the amount of calories burned in different activities. I would like to know, how many calories burn bicycling for leisure?

It is possible to estimate the calories burned in bicycling for leisure by using the MET data (Metabolic Equivalent of Task).
But weight is required in order to calculate calories burned.
I use Met Calculations for the following activity: bicycling, leisure, 9.4 mph (MET= 5.8).
Calories are per 1 hour of activity(same for male or female).
(man/woman) weighing 50 kg = 290 calories.
(man/woman) weighing 55 kg = 348 calories.
(man/woman) weighing 60 kg = 348 calories.
(man/woman) weighing 65 kg = 377 calories.
(man/woman) weighing 70 kg = 406 calories.
(man/woman) weighing 75 kg = 435 calories.
(man/woman) weighing 80 kg = 464 calories.
(man/woman) weighing 85 kg = 493 calories.
(man/woman) weighing 90 kg = 522 calories.
(man/woman) weighing 95 kg = 551 calories.
(man/woman) weighing 100 kg = 580 calories.
