alt Hacker NewsI think the main difference due to weight boils down to you riding in one gear lower when not using assistance.
On flat roads, I usually ride on 3rd or 4th gear (out of 7), now i ride in 2nd or 3rd.
But where i ride, the road isn't even and has a lot of steep slopes. There I'm on 1st gear all the time anyway and the assistance i get totally saves my knees, and ensures I'm not all sweaty when i reach my destination. Even compared to the light weight regular bicycles i rode before, this is better.
Once at speed you can maintain tempo in the highest gear on this bike. It does consume a lot of power that way but it is also really neat to be doing a 65 km ride in what is much less than twice the time that it takes to do that same trip by car.
