Bike Lock

edited September 2008 in Help / Advice Forum
I am looking for a bike lock.

I'm asking here because I really know nothing about bike locks, and which are secure. Things like http://www.youtube.com/watch?v=0DHYXApTwpw make me rather nervous, and I know a certain type of lock is vulnerable to being picked with a bic pen.

So HA, what sort of bike lock should I get? My bike is functional but old. Its not the end of the world if it gets stolen, since I didn't pay anything for it in the first place. I don't think I'd be willing to spend more than 30 dollars or so on a lock. I think I want something flexible and long so I can lock my bike to trees and assorted things more easily, and I'd probably prefer a combination lock to a key lock, for convenience. I'm not set on these options though, since they may turn out to be less secure than the alternatives.

HA, what do you say about bike locks?

    I'm happy with my bike lock. Its a TREK lock made by Kryptonite. It came with the U-lock and a half inch thick kevlar cable. While I know it can probably be picked easily, I am not really leaving it places overnight or somewhere that is likely to get stolen. Also, properly using the bike lock helps out a ton. If you want good security, I suggest a U-lock and cable like I have. Wrap the cable around the rear tire, and hook it into the U-lock which is secured to the bike rack and the front tire/frame.

    Pick a lock that is best for you. Where do you leave it at night? What type of area is it? Are there secure bike racks? If you're leaving it overnight is it well lit?

    Most of the time my bike will be left inside at my place, which is totally secure. If I was staying at someone's place, I'd do my best to lock up the bike in their back yard. Only very rarely would by bike be left overnight in a public place. Most of the use my bike lock would get would be locking it up while I'm going around town for the day, not overnight.

    Honestly, I wouldn't recommend leaving your bike outside overnight ever. It lives in your flat, house or garage overnight.

    But yeah, locks for daytime go, I could do with a suitable recommendation too.

    I've owned two Kryptonite u-locks and they both have served me well. I don't know much about the newer ones, but they've gotten good reviews. They are most effective when combined with a looped cable. Most of them come with a nice mounting bracket so you can stick it on your frame when you're riding to your destination.

    The wikipedia article on the subject is interesting: http://en.wikipedia.org/wiki/Bicycle_lock

    It seems that even high grade locks can be defeated by a professional in less than a minute. I'm definatley considering the low cost approach, just a chain and padlock. Since I wont be leaving it outside too much. Still looking though.

    If your bike is shittier then the average bike I would go with cheap low tech. Know where your going, there are places you just don't leave your bike. My brother's bike was locked with a midrange bike lock and stolen from a parking lot that supposedly had CCTV security. He found out after the cameras didn't work and had just been left up to try and discourage theft. He knew it wasn't a great neighborhood but thought he was covered.

    If a professional wants to steal your bike, they will steal your bike. No expensive lock is going to prevent that.

    If an amateur wants to steal your bike, a thick chain will usually deter them. I bought a cheap lock with a number system but the chain is stupid thick. It'd take a long time to cut with a saw and a snapper would probably have to be pretty heavy duty too. I also wrap the chain through the front wheel and around the handlebars then to the bike stand (if one is available). Can't go very far if the tires can't spin and you can't turn it.

    Now, I park my bike at places like a CVS or a Wendys or the bank. In the day. It'd be pretty hard for someone to cut through the chain and ride off with my bike with anyone noticing. At night, the bike is in the garage.

    I recommend locks for your seat and wheels also. I live in a college town with a ridiculous amount of bike theft. A lot of my buddies have chained up their bikes only to return to a wheel-less locked up frame.

    If an experienced lock pick wants your bike, they're going to have no trouble getting into it. Stupid thick chains weigh a ton, and some people don't like carrying them around. This is the appeal of U-locks and tethers. Is it easier to saw through a half inch of hardened steel or a quarter inch steel chain? Even with a bike lock, like people have said, there is still plenty of ways to get your bike stolen. Leaving your bike in a high traffic area during the day is the best way to protect it. Someone isn't going to take shears or a hacksaw to a bike when there are people frequently walking around.

    The dutch method is to have 2 different kind of locks, which gets rid of thieves who know 1 trick to open a lock, and to generally make your bike more hassle to steal then others around it. One of these is usually a ring lock like this which can be attached below the saddle and blocks the wheel from turning, and then either a chain or U lock to attach your bike to something solid (streetlight, gates, bike racks).

    Generally, U-locks are the most secure, followed by heavy duty hardened steel chains. Avoid cable locks as cable is ridiculously easy to cut through with a saw or bolt cutters. Also, avoid locks with circle keys as those are the kind that can be picked with a cheap ballpoint pen.

    Also, whether you get a U-lock or chain, make sure it is long enough to secure both wheels and the frame (most easily done by detaching the front wheel and placing it next to the back wheel and frame).

    Run a chain through both wheels and the frame. The thickness and quality of this chain should depend on how nice your bike looks and how high-theft your area is.

    Kryptonite-style U-Locks are the most secure bike locks out there. The newer ones have stopped using the circular keys that can be picked the way that video demonstrates, so just make sure you get a new one.

    Any locked bike is vulnerable to a serious bike thief. Even with a good U-lock, a dude with a torque wrench and limited knowledge can strip any number of valuable parts very quickly. Chains are harder to carry, and many of them also leave you vulnerable to anyone with a good pair of bolt cutters.

    It's worth mentioning that as with most consumer security devices, you aren't trying to deter serious thieves so much as you are crimes of opportunity. You want a lock that secures the most easily stolen and resold parts of the bicycle, and that is the most difficult for a layman to remove.

    For most bikes, the most easily removable and saleable part is the front wheel.

    If the bike gets left outside in a public place, or in the same place, often, then you want to use a U-lock. they can be more of a hassle because they only fit around a limited size and you need to remove the front wheel, place it next to the rear wheel and run the lock thru both wheels, the frame, and the fixed object. This locks up all the main components and also fills the gaps in the "U" making it harder to use one of the popular methods for defeating a U-lock.

    If you lock up your bike when you go to the store, then a cable lock is fine. You are stopping the theft of conveinence. The guy that would steal your bike just because it is unlocked will be stopped by even the most basic cable lock, but you are still better off using one with a beefier cable. these also usually let you set the combo to one you can remember, and are long enoug to lock everything without taking the front wheel off.

    Been said many times but yes. Thread it through both tires and the frame. I saw so many bikes downtown missing a front tire because they only threaded the back and the frame.

    Thieves generally don't steal seats, as those are worthless and a dime a dozen. They will steal gel seats though, so if you get one, get one that can be easily removed so you can take it in with you.

    Also if it's in front of a store with security cameras, lock it under the cameras. You're not depending on them actually having tape, but more for the fact that thieves will tend to not chance it. As said before, they go for what is easy.

    Get a keyed lock, by the way. I know kids that can solve a combo lock one in about 2-3 minutes, more than enough time if you're inside a place getting something.

    U-Locks are fine for most situations.

    I have a BullDog lock, similar style to Kryptonite. The key is more like an actual key. Amazon.com

    All modern U-Locks have been redesigned to prevent being picked with a pen. Seriously, that video is at least three years old.

    that said, if you get an old U-Lock free with a used bike, make sure it isn't vulnerable. I mean, there's a fuckton of those old, easily-picked things still in circulation.

    I use, and love, this lock. I'd imagine it would be pretty hard to open this unless you were really determined to get into it. I leave my bike overnight outside in a bike parking lot and it has yet to be stolen (knock on wood).

    Isn't that the lock that can be opened with a ball-point pen?

    All I have is a bicycle, and I use a kryptonite U-lock, which is what the LBS guys recommended. On top of this, I live in Gainesville, which is pretty much bike theft capital. I used to have a thick cable I'd run through both tires in addition to the U-lock, but I've since lost the cable and just have the U-lock now, which is unfortunate. It's stupid easy to remove the seat and tires on my bike, as I have quick release on both tires and the seat. As such, I try to never leave it locked out overnight or for any extended period of time, and just bring it in my house when I'm home.

    If you want to see if you have the bic pen pickable lock, get a bic stick, remove the ink cart and see if the white body can be fitted into the cylinder. If it does the lock is pickable. Not every lock that would fit the pen was pickable, but I was able to do about 75% of the locks in the shop. Once I had my technique down, I could pick one in less than a minute, often in just a few seconds.
