8th was blocked off , and a police officer told me it was only two blocks, it opened again at 62nd. So I was on Broadway when I had to downshift, and after that it was stuck in low gear. I docked the bike at west 63rd & Broadway. But then I walked to 8th and 68th, because I didn’t want to take the last bike. I did not earn an angel point for that..
Anyway, I was going to write down the problem, but before I could find a piece of paper, CitiBike emailed me to ask what the problem was.

Email from CitiBike. I pressed the red button on the dock to report a problem.


Repair questionnaire from the CitiBike app.

I could see what had happened. The shifter cable was coming unwound at the grip-shifter. Either cable lube went dry, or the return spring fouled at the hub.
I answered by checking “gearing” and “grips”.
I spotted at least 5 protests . I went to Harlem, and as far south as WSP. Also protests on the lawns of Central Park.
PS-The water fountains are on in Central Park, so you can refill your bottle.

Also very rarely, the high end of the shifting range isn't available. Comparing the NuVinci, Sturmey Archer, and Shimano hubs, the Shimano is my least favorite, but of the three hubs, the Shimano is the only one that - for me - has been 100% trouble-free.
