I'm a member of Citi Bike here in NYC, but I can't use it for commuting because I have a long commute, almost 14 miles. About two days a week, I ride my own bike. I have enough room in my apartment for a bike, and I bring it into my office at work and stand it up near my desk, obviating one reason for bike shares (interior space). The service area goes up to 110th St. I live near 10th St and work at 240th St, well beyond the service area.

Even if Citi Bike reached that far -- and I hope it does one day, for many reasons -- I don't want to ride those 50 klunkers for 14 miles. On the rare occasion I ride it 5 miles or more, it gets annoying and tiring.

I use Citi Bike for social and shopping trips. It has gone up to $155/year, which is still insanely cheap, even for me, and I use it less than many people do.

Occasionally, I'll do something silly like ride it from the station near my home to a station near the subway station, so I get in a half-mile-or-less ride. I do it because I'm dying to ride and will take whatever I can get. I may or may not save time this way, but I do gain a little fun.
