confused about consumed Calories

Hi all,

For a 75 minute ride on a stationary bike (kettler e5) the bike's computer gives me an estimate of 231 Calories (male, 39, 100kg).
This comes with other stats as well: 25 km/h, 70 RPM, 55 W, 117 BPM (all averages).

MFP estimates 75 minutes of stationary bike, light effort at 708 Calories.

Does anyone have an idea why this huge difference? I am using the bike's data because I trust them more at the moment, especially with the HRM. But I would still like to know why / how MFP ends up with this estimate.

Best,
C.

    750 is too high, 231 is too low.

    biking most accurately measures calories burnt compared to running/walking/ elliptical because it doesn't account into weight difference between people. It's purely leg strength.

    Burning about 375 kcal seems right for light bike.

    I usually just go 50% of what mfp recommends. Seems to work.
