You never know what you might run into when riding around New York, and as proof check out this shot from my commute home the other night.
Okay, so it's not the best picture, but what you are looking at is a pole dancing bike. The bike was featured in this New York Post article and the Web site dedicated to the bike is http://poleriders.blogspot.com/.
The site features lots of pictures of the bike in action, none of which are "X" rated but if you would not be comfortable say viewing the Victoria's Secret Web site at work, you will likely want to view it at home.
My favorite quote from the Web site, credited to Craziest Gadgets, is:
I spotted the bike on the Westside Greenway path which is very well traveled overwhelmed with people in the summer so I did not bother to stop and talk to the guy because I figured he had been bothered enough by questions as I rode by.
