Cycle Max Calories Burned?

[skatch]

It seems way higher than any other workout. I workout hard and my spin bike only said 350 calories burned at the end of cycle max. When I do a hard spin class for an hour, my bike normally says 500? Which one is right?

Probably neither. Calories burned depend on the intensity of the activity, your age, sex, weight and the effort you put forth. Calories burned as shown on cardio machines often do not take in all of these variables or the user does not enter them as required. Most calories burned readings on a cardio machine are for what they determine as an average person. Even then are only a rough estimate.
