This is an annual event organized by Times Up!, an environmental bike group in the city. I (Cassandra) did this ride a few times in the last decade and it was a blast. For more info, check out the official Facebook page:
Three meet-up locations:
9:45PM at the Brooklyn-side entrance to the Williamsburg Bridge
OR at 10PM at Washington Square Park Arch, Manhattan
OR 10:20pm Madison Square Park, 23rd & Broadway, Flatiron Side
Start the year off right- on your bike or skates! Come celebrate New Year's Eve in the great outdoors. We'll be riding up to Belvedere Castle in the middle of Central Park for the best (and free!) New Year's Eve dance party in town, with fireworks! Dress festive- don't forget your noisemakers and party favors- and bring food and drink to share!
**If you don't want to do the ride, you can just meet us at 11:45 at Belvedere Castle.
