Yes, the workout controls the resistance, but based on the workout goals, not based on the terrain. I might be wrong about ERG mode in free ride. I only tried it I think once, but I thought you had control over the level of the erg such that you can spin at the same rate (and watts), and the speed of your bike will increase or decrease, based on terrain. but I could be wrong about that. I don't use it very often.
Personally, I like the SIM mode and switch gears. It's far more like being on the road.
