My lock sucks. What are the most effective? What are your favorites?

depends on how you want to lock up. but a nice mini u lock and a chain is probably "best"

I use a kryptonite U lock, a cannondale U lock, and a security chain with storage unit lock in various combinations depending on the situation. You can get security chain with a fabric sleeve for cheap at harbor freight. There has never been a reported bike theft of a bike locked with a U on my campus so I feel pretty safe. I keep my Soma in my room if I'm not riding it to class or a meal though.

I have a Krypto mini for most of the time. Currently I'm using a bigger OnGuard X4 Power for my MTB though. I'm also going to get a cable to add a bit more safety.

Everyday use kind of bike, ulock+cable seems good enough to me, as long as it's lock up good enough.

I use a Krypto Fuggedaboutit NY lock with the Sheldon locking method; haven't gotten jacked yet.

trained pitbull, tie it to the bike rack. no one is coming near that thing.

I use an On Guard Bulldog mini with a cable. Cheap. Good.

Sheldon-locking happens every so often, but it's usually the u-lock through the rear wheel/seat tube and a cable through the front.

With a cable that's not ridiculous to carry around, can you fit it to the ulock to the saddle, front wheel, and back?

I have used old tube and old chain for saddle

To the saddle in addition to the frame and wheels, I would say that's quite a stretch, so no (if you're ambitious, you'll find a way).

For those wondering: a similar representation.

I use a Kryptonite Evolution Mini Bike U-Lock. $40 off of Amazon. Use lock to lock the frame and front wheel to the bike rack.

Just leaving this here for the sheldon brown lockers:

and that's why you put it round frame and wheel. but seriously if someone is that dedicated then they will probably get your bike. also if you lock it somewhere where that will happen and no one says anything then 1. you have stupid neighbors 2. you need to lock it somewhere better

Blackburn Sing Sing (I use it instead of the Krypto Mini Evo nowadays) hex shaped U and double locks instead of single sided on the K .
I like the Krypto because it's all rubber coated, Blackburn only on the inside but hasn't been an issue.

The Krypto NYF is the best but it is pretty heavy.

Never use just a cable lock, only use it as a secondary.

If I were locking up for any length of time, I would use 2 U-locks (different brands) and a hex, hardened chain.
Paranoid and heavy, yes.
Don't like one way trips w/ my bike, yes.

IMO, at least one of your locks should be a NYF

edit-
I've seen that Sheldon Brown hack but usually, thieves like to ride off on the bike or have the bike otherwise complete.
It's a good warning though.
I lock higher up at the seatstay and rim, that way the frame and wheel are both locked.

Locks are a deterrent. Any lock can be defeated. I use a Kryptonite u-lock on the frame and front wheel (when convenient) and nothing else most of the time.

With one cable it's difficult. With two cables, it's easy as pie. Kryptonite makes a range of cables in different thicknesses and lengths that you can use. Excuse the excessive pimping of Krypto, but they're the only locks I use.

Agreed. Krypto is my favorite, but OnGuard makes a good lock also. Either one are perfectly fine for me. I was hoping I could get the smallest cable and be able to secure my front wheel and saddle, but I guess I can just get one a little longer.

As for that video EpicSchwinn, I always thought the Sheldon Brown method was to have a ulock in the rear wheel AND on the frames triangle. Guess I DON'T use Sheldon's method.

This is the best value chain lock, in my opinion. Also, regarding where you lock your bike, it's questionable whether high visibility is a deterrent.

That's crazy how little everyone cared.

I got an Abus lock For my bike I have 2 with me, the Link lock folds and goes in a pouch

the Armored cable lock hangs from the bars , and I carry a loop end cable
then I can secure both wheels and the frame to a fixed object..

needing to tool up for several different types of locks is a handicap for the miscreants.

Thieves want wheels, especially if you have a nice bike with some nice wheels.

I carry my bike inside my classroom if my teacher doesn't care (which they never care). Other than that, it's always in my room.

I have an Onguard mini on my Kilo TT. Unless your bike is in like 5 digits I don't think it's necessary for the NYF lock I almost thought about getting. If I could do it again I'd probably get the Kryptonite Evolution Mini with the cable lock but it's really just the brand.

that abus looks great, I like how different it is. (different design means the thief has to have multiple tools)
The pivots seem like the weak link- can they be pry-barred apart or split?

might have to get that abus...

here's a nice thread about bike locks

Stolen bike or any of its parts should be a celebration: time to get a new one! Woo! Its such a long and daunting process for parts to breakdown on their own = (
...however: that does not mean you should tie your bike up with a shoe-string. Like someone mentioned earlier: any lock can be hacked (Kryptonite evolution take 4 minutes on a battery operated saw and Fugghetaboutit takes a whole 6 minutes of sparkflying action).

Neistats are really getting into cycling aren't they? Good looks

answered in the quote

cruiserhead: I own a couple of bicycle locks, which includes both the Evo and Fughettaboutit. However I am under no illusion that the NYF is indestructible. As far as U-Lock floggings go: I see an advantage in utilizing Evo. It is lighter and thus can be controlled better in mid-swing. Heck, a roll of nickels is just as potent.

I had bicycles stolen. I got over it. I hold no anger.
