Twofer - thanks for wanting a Kryptonite for your new cycling adventure! You are correct in thinking you need either a U-lock or chain in DC!

Jimbo is right, the New York 3000 is now, just simply the New York Lock. However, motorcycle and scooter dealers wouldn't have this because it is a bicycle lock. They'd most likely have the New York MC. They also wouldn't have any of the other U-locks, as these are for bicycle, too. Motorcycle/scooter dealers would have chain, as you found out, or disc locks.

If you are looking for the New York M-18, which is a motorcycle lock, please do give customer service a call - in the US the number is 1-800-SAY-LOCK. They may be able to help you, or one of our online partners as Walkafire mentions.

If you don't want a chain and aren't comfortable with the New York Lock for some reason, the M-18 is a good (heavy!) choice. In stores in a month or so will be the New York Fahgettaboudit U-lock, which has more steel than the New York Lock, but is a 'Mini'. This is for exactly what grolby was talking about! You can view it over on Singletrack's site.
