    No experience with it, but I wonder how sensitive it is to motion. Is it going to go off if someone locked their bike next to yours on a rack and jostled it? That wouldn't be good.

    It is important to understand that Lock Alarm is NOT motion sensitive so accidental knocks from passers by, windy conditions, movement caused in transit etc. will NOT cause the alarm to sound. Basically, if the alarm sounds, it means someone is forcefully attacking the cable or the main unit.
    Not sure about the other one. Sounds like a good idea - as long as you are close when it goes off. Otherwise you get the situation like with car alarms - everyone ignores them. Might get people to at least look - just because most bikes don't have alarms.

    I've thought about getting one, I think i'd rather find a way to electrify the bike (maybe after a few warnings) still not foolproof, but I think anyone would think twice before getting tazed for trying to steal a bike.

    With an audible alarm, the previously mentioned problem of having to be close enough to it that you can hear it exists. otherwise you rely on nice people intervening on your behalf.

    Despite the gimmick of an alarm these look like poor quality locks. You'd be better off spending a little more on one of the top of the line chains or u-locks and not relying on strangers to confront a bike thief on your behalf.

    Agreed. The lock mechanism has to fit in that little 'box' along with two batteries and the alarm circuit. I would rather have more metal in the casing and a thicker lock.

    On the electrified bike posts most states have laws about "Man Trapping". Any zap strong enough to do any good might kill some Senior that brushes against it .

    Uhh, multiple locks...

    Most lock recommendations mention have a cable and a chain/u-lock so that a thief who is set for one type might think twice. Having something that will draw attention as well as a more sturdy type is good. Face it, most locks are not going to stop a determined person - just slow them down and/or make them find an easier target.

    It might make a good 2nd lock for those of us who use more than 1.

    Bike thieves are like car thieves, they depend on the quick getaway, most car thieves depend on being able to break into a car, start it and be underway in less than 15 seconds, and a bike thief also depends on a similar time frame, if they can cut your lock and be underway in under 15 seconds, then your bike is history, and likely with the alarm lock, the lock will be sitting there screaming long after the bike is gone. Okay maybe it stops screaming, when you take a blunt object and beat the living daylights out of it .

    Two locks doubles the amount of time it takes, and requires different tools, one possible "lock" is to keep a spare spoke around, use it to hook the chain, and drop it beside the small chainring. The thief then needs to hook the chain back on, and cut the lock, that takes too much time, and they will grab the next bike, that has the kind of lock they are looking for. Another deterant is to use a seat quick release, and take the seat with you, now the thief needs to attach a seat, put the chain back on, and cut the lock.

    Of course, some thieves will stand to avoid the seat problem, except they missed the unhooked chain, and just ended up with a nasty groin plant Of course, you need to make sure, you rehook the chain when you return.

    i've got one of these!!!

    Hiya,

    I haven't tried one of the alarms mentioned above, I purchased this little neat device that I found on the web. www.timani-ltd.com This is such a great device... but still got a nice big chain lock ;-). Cheap as well! Had my bike stolen before and its such a pain. Hopefully just having something else other then a lock will make people think twice and go for the next bike. I don't want any1 to have there bikes stolen but at the end of the day it happens.

    If you got a good lock go buy a cheap personal alarm fasten the unit up under your seat and the lanyard to your wheel. If some one beats your lock and tries to roll away the pin will get pulled setting the alarm off. I use one my self if i plan on going in some place for a extended period of time. Had some one try to take my bike they didn't get very far hehe.

    you would need to take a crappy nalgene and throw the chain in that and then take it in wid you I wonder if the chain would last after taking it apart and putting it back together a whole bunch instead of riding away they would have to walk away but even after 6 minutes in the neistat bros film it shows how ignorant people are or unkind
