Now I see what you mean about the NuVinci not providing the highest ratios, though I can never be sure I'm missing out. My first bike offered a very high highest ratio, so that must be working. Today, I took a 6.7 mile joy ride on Citi Bike, and I'm pretty sure I wasn't getting the highest ratio. But it was OK. Does anyone know what goes wrong inside the hub?
I ride with my seat low on Citi Bike. It works for me. My knees do straighten out, but I try to pedal with my arches. It turns out to be better than I thought. I've injured my feet permanently pedaling with the balls of my feet.
I have posted earlier, it seems that the hub has to be installed in full overdrive position:
Citibikes have started!
As for the slipping pedals, I rode another citibike this morning again, with the ice grippers on hand in case I needed it. I did not encounter any slip w/o the ice grippers, even though the weather was pretty cold.
Suspecting it was due to me not walking over snow before mounting onto the bike, thus having a layer of snow on my sole, allowing some slippery film to form, I smeared my feet in some pile of snow but there were no slip. I also stepped in some puddle (albeit salted) and it was still the same. I did notice the surface of the pedals were a bit worn, maybe the plasticky surface that has such low coefficient of friction when cold has worn off?
