Yes your answer is most helpful. I was referring to the scenario where you compare the physical effort required between your DT, and the Carryme on a paved surface at speeds between 10-15 mph. I do understand the DT has a higher top speed potential because of the gearing, but as you state, it does take more effort to reach, and sustain.
Thanks again,

So while on the open road the extra gearing starts to earn its keep, for stop and go the Carryme is king.
I run 2.0" Big Apples on the DT, the stock Carryme tires are 8x1.25", and my 700c bike has stelvios. So as far as terrain, rough surfaces with many small imperfections are best with the 700c followed by 20" BAs and finally 8". Grass is also best with 700c, hard with 20" BAs and almost impossible on 8". Wide tires like 20" BAs are a must for unpaved paths with sand or roots and although 700c can do hard packed trails 8" are for paved roads only. However, on paved roads with large obstacles such as curbs and potholes neither larger wheels nor fatter tires help and smaller diameters win out for being nimble enough to lift, wheelie, or steer around in order to reduce impact or maintain control.
Hope that helps.
