On my visit to NYC, I found the Citibike system to be a great way to get around town. And lots of fun as well, if you don’t mind the NYC traffic (it’s a thrill to bike through Times Square).
I got the 24 hour pass, with which you get unlimited use of the system. But you can only use it for 30 minutes at a time. But with most places, you can get to within that time. And there are a lot of stations all over. I used the free app to find the stations and their availability. The app also shows the bike lanes.
The bikes have adjustable seats, 3 gears (I only used one, didn’t need the easier ones), and a front rack/basket (used it for my camera bag). The brakes work well, especially when a huge bus wanted to make a left turn in front of me. It took a little while, but I got used to the weight and handling of the bike.
