Calories?

Christinichka

So I own a stationary fan bike. I biked this morning for 32 minutes. My bike does not take in to account weight and what not. I feel like I was keeping a pretty moderate pace. But when I try to log as stationary bike at moderate pace it gives me almost 400 calories. Whereas my bike says I burned just over 150. That's quite a difference. But I am sure the bike goes off of a burn for someone much smaller than myself. So I know I burned more than 150 but just not quite sure if it was quite as much as 400. Any advice? What would you do?
