With stationary bikes, the calorie burn is heavily dependent on the resistance level.
The bike knows your resistance level, while Spark is just making broad assumptions about resistance.
If the bikes estimate is low, this is probably because you were using a low resistance level. And in which case, there is good reason to go with the bikes estimate on this one.

I rode the stationary (recumbent) bike today for 35 minutes (which includes my cool down). I went just about 12.5 miles. The bike registered calories burned as approx. 175. When I look up the same thing in the fitness tracker, I'm showing that it's closer to 360.
How in the world do I know which is correct? When I google it, I'm getting a range between 215 and 400! Oy.
