I felt the need to ride a scooter and the citibike was all that was available.


Anyway, on my morning ride, I was looking for bikes with NuVinci hubs to ride, given in the last couple of days with the wind and cold, the S/A equipped bikes' top gear felt too high (with the legs not able to fully warm up to power thru them) and middle gear felt too low. The first one I got had the shifter stuck. I rode it to the next station where I switched it to another NuVinci'd bike, and this one's shifter was also stuck (in overdrive, no less, making pedaling in lower speed almost impossible). I docked it again searching for a bike with a good NuVinci shifter and felt few where the shifter didn't move. I eventually got a good one and continued the rest of my ride.


Is this a known issue with the NuVinci shifter/hub, especially in the cold? I presume the lubricant won't freeze. Nor should the traction fluid, unless the got those fluid in the parts that parts that does not need it and it became seized in the cold.

On my way home, I found another NuVinci bike with the cables starting to unwind out of the shifter mechanism by the handlebar. Maybe the user tried to twist and twist on a shifter that refuses to shift?

On a note, I searched the information superhighway and came upon this article on the issue. I can only guess the freezing rain from a few days ago seeped into the internals and froze the shifting mechanism
