True again... I am just pointing out that most people here, seem to totally UNDERESTIMATE how much extra they would need to do to burn the same amount of calories that using an assist causes you NOT to burn in a given distance, and how it multiplies the distance one NEEDS to do, extra, just to break even... The higher the assist is the worse it gets, with lets say a 750 watt system or bigger. Or even the same as mine, a 350 watt, but a mid drive, that really increases the efficiency of the assist and how much one gets out of it to relieve oneself of pedaling effort thus calorie burning, must be even worse (lower) ...
