I hadn't ridden any bike in a while, and last night, I decided to ride to my choral rehearsal, 4.8 miles each way. I took Citi Bike and brought my ski helmet for warmth. My route has snow, ice, and slush on it, and the bike handles those extremely well. 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.
