After witnessing the bike theft...I've been thinking of ways to beef up security. One thing is dual locks. I see them all the time. It might actually be easier than using a cord, and of course more secure.

Ideally, there would be a way to have two locks work with teh same key. Anyone?

If you have two locks with different keys I'm sure a lock smith could key the locks to be the same.

Why do you think that would be more secure?
The concept behind using a U-lock and a cable is that it forces the thief to bring two different, both relatively heavy, tools with him.

because you can defeat the security cable really easily with a wire cutter which fits in the pocket, and because compared to the cable, an extra u lock, especially the compact kind, isnt much heavier.

don't use a cable as the primary lock unless you need big boltcutters to get through it. At that point, the weight of the thing is probably obscene and a U-lock is a better choice.

I noted while visiting their web site that Kryptonite offers NO "bike theft insurance" with any of their cable locks. That tells me that they do not consider any cable lock to be even close in security to a U lock or heavy duty chain lock.

Even if difficult to collect on for a bike stolen while using a Kryptonite U or chain lock the fact that insurance is not even offered for their cable locks says a lot about what they consider the security level of them.

To clarify...

currently I use a U lock and a security cord.

I'm thinking of switch to using two u locks.

Currently I use a compact U lock, Kryptonite or OnGuard, and a relatively light Abus chain lock on most of my bikes. I figure almost any chain lock should be more resistant to attack than a cable.

The exception is my urban hauler grocery bike. It has a Axa Defender ring lock mounted to the frame along with the optional chain assembly that locks into the ring lock body. The handiest lock for urban use in low to medium risk areas IMO though I did need to make a mounting plate for the lock in order to mount it on my Swobo Dixon. The standard mounting is designed more to fit a steel frame's seatstays.

Lots of posts on theft. The only new thing I have seen is GPS trackers with text messaging, which might help you locate your bike.

I just had a thought. You know those microchips they put in pets if they're lost, how about one for your bike? Does that kinda thing exist?

Currently have a cable lock, looking at adding a security chain & either a U-lock or a trailer hitch lock for the chain. Very few places I have to go right now that require locking up. By spring, I will be a LOT more secure....

This is all you need!!!

The ABUS monobloc locks are cost effective to buy and real easy to key alike, make things very convenient. We do quite a few every month at our small shop. Most locksmiths also have a kit to "key alike" and will charge about 6 bucks per lock if you have an original working key.

There are not many locks that I would trust and they are expensive. I currently have a Kryptonite U lock and a Kryptonite hawser. I lock the frame- rear wheel and what I am locking to together- and if possible the front wheel is taken off and also put in the U Lock. The hawser will the lock the saddle and all of the bike to the lamp post or Bike rack. I would trust this lock for about 5 minutes to a determined thief.

But the dual lock system--- I see this used a lot in Brighton (Plenty of students and bikes there) The theory is that it is easier to break one lock than two so the thieves move onto an easier to steal bike. But if the bike is what the thieves want-- it is going to go.
