Stationary bike calories

[Alexbfru]

Hi, I'm clpletely new to fitbit and calorie tracking in general.

I've just done a session on an exercise bike and the calories on there differ to what my device has recorded.

I did 20km in 50 minutes and the bike said around 740 calories while the workout under spinning on the fitbit said 490.

I cant enter weight on the bike so I'm not expecting it to be completely accurate but 250 more seems quite a lot.

Does anyone have any advice on what I could do to see which is the more accurate figure please? I've seen something about manually logging but I'm unsure.

Thank you!

Is your stationary bike made by one of the many manufacturers that intentionally add "Feel good", calories? Yes, even some name brand units intentionally report to many calories to make the user feel better. 

Does your bike measure the heart rate? 

As for the calories, these are really based on math and expect the user to fall in line with what they call an average user, are you average?

Thanks for your reply.

I imagine it is one of those manufacturers but I thought 250 was a bit too generous with the feel good calories.

It does monitor heart rate and that was pretty much spot on. And I would say I was an average user.

I really don't ha e an answer, just trying to point out a possibility. 

Also each company uses their own touch on the math to calculate calories. 

Personally I never worried about calories and use Fitbit to quantify my activity then watch my food intake. Instead of two - dishes for dinner I'll stick with 1 and maybe a little more. This has been enough monitoring to lose 35 pounds.
