Commuting - [nyc] any tips on locking a Mountain bike in NYC?

I just got a mountain bike. A rockhopper specialized from 97, and I am planning on using it to commute in NCY, on the greenway (goes around Manhattan). I work downtown by the WTC, and I am looking for tips on securing this bike.
I am considering getting the Kryptonite evolution mini u-lock, to lock the back wheel + the frame to a cityrack. I also want to use a cable lock for the saddle + front wheel + frame. It will be locked on the street during the day, but the building has security guards and cameras.

Any advice on this? For example, is the evo mini big enough to lock frame+wheel+cityrack? Do you know of any safe area downtown? Any other lock recommended?

Any other tip is welcome.

Ideally, your employer would let you bring your bike into the office and store it somewhere discreet.

Any lock can be defeated. The idea is to make it difficult enough that it becomes not worth the hassle.

I would use both a cable lock AND a U-lock as they require different strategies to defeat them.

For more security, remove the seatpost from your bike. For even more security, remove the front tire. Its real hard to get away with bike you can't ride away on.

I use an On-Guard Mini ulock which is the same size as the Krypto mini along with a cable.
I use racks here in boston almost identical to those nyc city racks.

With my mini U lock I can lock my back wheel (inside the rear frame triangle) to the rack pole, but there is not enough space to fit the rear frame in the u-lock. I whip my cable through the front wheel and into the U-lock. As for my seat, I took it inside with me for a long time, since my cable is too thick and too short to extend though my seat rails. Then I found a bike chain, wrapped it in an old inner tube, and secured my seat to my frame with it. I no longer worry about my seat being stolen.

The rear triangle method (http://www.sheldonbrown.com/lock-strategy.html).

A thief must now have three separate tools to steal my entire bike (one for the cable, one for the U-lock/rear wheel, and a chain tool).

Also, don't rely on security cameras to offer any security.

Thank you for the tips.
I asked the security guys, and I am not allowed to park inside.
I will use both u-lock and cable The cable I have is http://www.locksrock.com/item.asp?CID=2114). I also read that some poeple advise to 'randomly' change the location of parking. Is it really necessary?

I think it is a good idea to randomly move your bike location. However if you can park your bike in front of the building or by a camera or security guard leave it there. You might want to slip the security guard some extra $$$ now and then also to keep an eye on it.

I'm a big fan of the heavy Kryptonite chains through the frame and one wheel, and I guess I'd use a U-lock through the frame and second wheel. Take the seat inside with you- you probably have a quick-release seatpost lever on that bike, right? Check the seat tube for 'presents' once in a while.

I'd also try to leave the bike as close to the building as possible, in line-of sight to the interior, if that works.

About the security guard, just getting to the point where you're polite and say 'hey' to him every day is big, and if he can see your parking spot from his station, he might shout at a thief for you. $$$ to him might get him fired, but I suppose that kind of situation could be different building to building.

Good luck on the commute and parking- that bike should do really well for you.

Also use Pitlock or Pinhead locking skewers for your wheels,might also want to get the ones for your seatpost collar and topcap.

Yes. Don't lock it outside in NYC. It is just a matter of time. Take it in or find a secure parking stn for the bike.

Perhaps a nearby parking garage has an indoor lockup spot? I know that some garages in DC have racks down in the garage.
