Jersey City have been getting bikes with the NuVinci hubs. The few that I have ridden, they seem to have adjusted so that I can engage overdrive.
When I take out bikes from docks and I see bikes with NuVinci hubs, I try to twist the knob to see if I feel the indentation at the end of the turn. Today, a couple did not have that feel, and a third one seems like it did. But once I started riding, the feel was not there, and I had to ride the whole way at a middling pace.
I will have to get some reference feel of the shifters on the Jersey City bikes w/NuVici hubs.
