Try nycc.org they have a lot of members and generally there's always a few rides orgranized each weekend that do the Over-the-GW and up north routes... and many other rides in other destinations.

agree with that
[MENTION=392045]yankeefan[/MENTION] i found that joining strava opened up some clubs to me that now stay on my radar.

and - there are tons of planned free rides out there, many of which are friendly for all levels:

i find this website managed by TA super helpful. best of luck and get out there! :)

Nyack Ride May 3rd
 

We're leaving from Hoboken @ 7am, but can meet at GWB at 7:45. It should be a great day.

That's the same day as the 5 Boro Bike Tour :(

I'm game for Saturday morning if possible

This Sat. Is not so good for me. We're riding every Sunday, so if you want to join us on another ride just let me know.

mgw

zoom26 from Yonkers, I know it doesn't count as NYC but almost though. Can contact me through pm.
PS
Is there a folding bike community around NYC, esp dahon owners?
