True. The more one rides the more calories one burns...
BUT, HOW much more does one need to ride to accomplish that? Time isn't really the way to figure it out.
If you look at my "chart" in post 2, it would take me riding my bike x times farther just to equal, what it would take if riding without any assist, it adds up BIG time the higher the assist level used...
Level 1= 1.4 X farther, 9,341 Km instead of 6,672Km.
Level 2= 1.7 X farther, 11,342Km instead of 6,672Km.
Level 3= 2.3 X farther, 15,345Km instead of 6,672Km.
Level 4= 6.6 X farther, 44,035Km instead of 6,672Km...
And that is just using a 350 watt MAX assist system, no throttle, or cadence assist where you have absolutely no idea of how much assist is actually given...
EDIT; As you can see, on level 4, I would need to ride my bike 44,035Km to = 6,672Km that I actually rode... WOW, if I didn't do that I would be missing out on burning 223,108 calories...
