I've read many similar accounts, especially for people on bents and trikes, that this is exactly what they're doing. I say, more power to them. But I'm not a competitive cyclist, I hate riding in any groups, and I only ride for commuting, exercise, and fun....by myself.
Let's put an HR monitor and power meter on an e-bike rider and see how much they really burn. My guess is maybe 20% of what a decent rider puts out, if that. They are spinning the pedals just enough to have the motor kick in. You don't get much exercise that way.
