    Best locks for Downtube

    Hi Everyone,

    I don't yet have a lock, mainly because I don't know which one(s) to get. Years ago, I had a bike that I'd locked stolen while I was in the library for 15 minutes (Glendale, California). Today, I finally figured out a route to the library here in Palmdale, rode the Downtube there, and before I could fold it up, was told that I couldn't bring a bike in the library, whether it folded up or not.

    Before I go back, can you all recommend a lock or locks? What's the best way to lock it?

    Michele

    Not for nothing, but doesn't the Downtube come with a carry bag? Once it's plopped inside the bag, you're not carrying a "bike" into the library, you're just carrying a bag.

    As long as you pack it up just around the corner from the front door.

    And as long as they don't check bags on your way into the building.

    When folded, it's "bike parts" in the bag. Always works for me.

    Bike parts inside a bag works everywhere. I use El Cheepo Kriptonite.

    I also believe people in charge of the library do not have X-ray vision. So if you take a "bag" inside the library will it be ok?

    Long answer: Most Krypto's stink. I wrote a lot about locks (which ones are best, i have been researching this topic for years) check out my post in the thread entitled 'Your Brand new Kryptonite..."

    Short Answer:

    ABUS Steel-O-Chain 810 AND a Axa SL -7 or even better the AXA Defender

    http://axabasta.intermix2.nl/index.a...tems.asp?id=11

    Never use the Axa as your only lock unless your bike is in constant view.

    The Abus can be used stand alone, but i like having the Axa as back up when the hood is bad or i am leaving the folder for long.

    I use a massive u-lock and a cable for the wheels and the saddle. Unless you live very low crime area, don't use a cable lock only. Also don't use a u-lock with a cylindric key. They have been proven to be unsafe.

    Not being able to bring my Swift folder into a building would be a real bummer. Locking it up will be a pain. I would have to take the seatpost with me (I guess a good thing), secure both wheels and the QR stem riser.
    Can anyone recommend a bag for the Swift folder?
    I know Dahon has one, will it work with the Swift?

    Identifying your folded folder as bike parts seems to work in a number of situations (I hope)

    Locks? Don't even think about it. There are no locks in the world a portable grinder can't cut thru. One of the main reasons for folding bikes is so; you wouldn’t have to lock it. Use a Bag or cover never bring a lock because it will add more weight to the bike and after awhile you will start using the lock more and eventually your bike will be lost.

    There are just times one can not use a bag or carry in your bike. I live in the one of the worst cities in the world when it comes to bike theft. Rotterdam. It is only second to NY i think.

    With the locks i have i have never had anyone even try to steal my bikes. I leave my bike outdoors overnight every day. I leave it in the city center (where theft is at it's worst) during the day time. My chain can (almost) not be cut with a boltcutter and with a grinder it will take relatively long and make heaps of noise.

    It is simple logic and diminishing returns. If my bike is less valuable than the next guys and has way better locks and represents a lot more work and risk a thief will move on. Simple as that. I think i am in the top 1% to top 10% in terms of good locks of Rotterdam cyclists and my bike is bottom half or even quarter in terms of resale value/looking fancy. Hence i don't have to worry much, if at all.

    I'll gladly carry the 1.5 to 2 Kilos my locks weigh together in order not to always have to fold and carry in my (wet) bike. Lugging a bike is a hassle no matter what. Folding it every time you need to go indoors isn't a pick nick either. The two locks i employ don't require more than 10 seconds to lock and after that i don't have shuffle about indoors toting or rolling 11 to 15 kilos everytime i decide i want a candy bar or DVD or need the bathroom or whatever.

    If you need additional protection against theft 'uglying up' your bike might be a plan. Matte Black bar tape can be made to look ugly if covers most of the bike, doesn't weigh a thing and can be removed easily if one needs the bike 'pretty' again.

    Oh yes, i have also made sure i don't have Quick releases on my bike. I don't consider needing a hex key (and possibly a spanner) once every month a big deal. I carry them a lot anyway when i do longer rides. I prefer it over losing my saddle or not being able to tend to small problems on the fly.

    But my locks are capable of securing both wheels AND locking my frame to a sturdy post at the same time, so even if i did have OR wheels,.. not a problem.

    its like the two scuba divers who encounter a very hungry shark..... you do NOT need to swim faster than the shark,, just a little faster than your buddy ...

    Vince is absolutely right... as long as YOUR lock is a little stronger ( or looks stronger) than the next guy , you are in good shape...... thiefs are lazy

    I hate carrying U-locks and chain locks with me on my folder, however cable locks are not so bad. I have a fat Onguard cable lock that I wrap around my waist on short rides.....I hardly notice it. On that note I would take a cable lock, and lock your wheels and seatpost outside. I doubt anyone would steal 20" wheels or a super long post. The rest of the bike should be dramaticlly smaller and lighter in the bag. Overall I think this is a good combination of convenience and safety.

    Thanks,
    Yan

    While having my Sons' new Downtube FS tuned-up at the LBS I bought a Specialized cable lock that clips to the included bracket. I'll post pics right now if I can.

    The Specialized lock mounted in that position in no way interferes with the operation of the bike. Not even when the bike is folded and resting on the support below the bottom bracket.

    Thor, that's a good generalization, but it doesn't hold for Moulton thieves. They hunt like cats, they carry the best of cutting equipment, and they are most industrious.

    Agree with v1nce all the way.

    ABUS steel-o-chain has been awarded in Holland and Belgium for being the best bike-lock in 2005

    And not everyone who ownes a folder wants to carry it around all the time. Some buy it because of lack of storage-space, others because it fits in the trunk of the car, or because its 'cool'.
    All 3 reasons count for me.

    So a decent lock please !!

    I always wondered about a lock which LOOKS like it could secure Ft Knox ( supposingly the place where the US keeps it gold reserves,,,, SUPPOSINGLYi..lol )

    anyhow a lock which looks like it can withstand everything...BUT its made out of superlight plastic and COULD be snagged like a twigg...

    Abus locks are the best ( at least the more expensive ones ) but can be hard to find. I tried to sell them in the US but the supply chain ( distributors than to dealers, to consumer ) did not understand the quality and did not want to pay the price for them, the consumer lucked out because of it .

    ....when will Americans learn: products made in Europe and esp. Germany are the best of quality !
    Look at Mercedes, BMW, Abus(?), Alfa Romeo (Oh no sorry, that's my car and I wish it would be German )

    Hey Guys, i hope you people don't get bummed out by the following, but i am not posting to try and be a wiseguy, but because i hate anyone to lose his bike to theft.

    The Steel o Chain is not only excellent but affordable.. About 34 to 38 Euros retail. Compare that with their Krypto equivalents that despite of/because of their huge links, hefty weight and often faulty cylinders weigh almost double and are only half as strong and cost 60 to a 120 dollars! Bad metal and inferior hardening and faulty cylinder can't be compensated for by brand recognition or more 'beef'

    Even their top of the line Faghetaboutit (that could be used as the Titanic boatanchor in terms of weight) is vastly inferior to the Abus. I forget but i think it costs in excess of a 100 dollars.
    If people really can't source the Abus and want them i'd gladly send out a couple.

    @ Yan, really interesting idea though it would not be practical for my use. People do steal seatposts and seats here and the municipal services will cut locks and remove bikes with longer term flats or other small problems that suggest they are not in operating order. They do this so the city doesn't look 'messed up'.... Pretty messed up policy if you ask me. A set of wheels and seat wouldn't stand a chance, Big Brother would take them quick and they would likely get vandalized by the natives as well.

    Lastly it involves not only folding the bike and often bagging it but removing and re installing vital components every time you want to do even a minor errand. Then when you come out you have to make sure the post is set to correct height and straight, that your rims don't scrape the V Brake. To me personally it seems like way more hassle than carrying around one good lock. Especially as you still need to lock up your components, even with a very light cable lock.. But if it works for you i am not arguing with that!

    As for the cable locks, not to piss on anyone parades but they are really the very very worst locks out there. If you just lift one you know they have no substance whatsoever. Give me 1 to 4 minutes i can even break/cut it even with my Multi Tool, no exageration. A discarded stick that is twisted around will often even make the alleged cylinders pop. A thief with a bolt culter is going to simply crack up and have a field day.

    @ kpinvt, if your son likes his bike and wants to keep riding it i really suggest you toss (or use it for the shed or something) and replace that lock asap. It is almost akin to locking your bike with a sturdy Nylon Rope, i am utterly serious.

    I am not just making this stuff up. In the aforementioned authorative test (and a few more like it) the 'Fietsersbond' tested all the lock types and interviewed (proffesional) thieves at length. I know some shady characters (not friends, acquintances) myself and have very extensive experience with locks and breaking techniques (mostly house locks about 400 but also some 20 bike locks i cracked and the techniques are very similair) due to my squatting background (no, i am not a bike thief). All this confirms what i write about cable locks.

    The very best cable lock, the Trelock, SK626 (probablu unavailable in the states as well) had needed only 11.6 Kilonewton of force in order to be cut. The Abus chain needed 51 and additionally had a rockwell hardness of 66 C, this is harder than even the very best boltcutter. The Trelock cable is only 10 Euros cheaper than the ABus chain and this TreLock is probably between a quarter and twice as strong as the cable locks that are mentioned in this thread. I can't make it any more plain, cable locks are utter Rubbish.

    Additionally i see cable locks lying cut or broken open on the street every day. More than any other type i see these locks lying useless and a testament to someone's totally misplaced trust in them..

    The conclusions of the test were: Only good hardened chains (see the top 7 below, some of the better ones are easily available in the US as well) and the best U locks were worth spending any cash on.

    All the rest were next to useless, the types included but were not limited to: Badly or non hardened chains, cable lock, cable and segment locks, extra thick cable locks etc etc.

    It is my belief that if you are going to employ a lock (rather than carrying in a bike or Yan's strategy of course) your lock needs to be the very best possible/the most important component on your bike. What use is a DT, or a Litespeed or a Phil Wood hub or anything else you love for that matter if you scrimp on the lock and it is all stolen from you...!

    2 Cordo kettingslot Stone (910/100) 48,8 64 8,1 € 37,50
    3 Abus Winner-Chain 92W65/8KS ** 48,3 66 8,0 € 41,95
    4 Bumper Chain 31, 90 cm 47,0 59 9,6 € 29,90

    V1nce, I see that Abus Steel-O-Chain 810 comes in 8mm and 10mm and in the following lengths of 85cm and 110cm.
    Which one do you use?
    I wonder what the 8mm 85cm or 10mm 110cm weigh?
    Do you know what does the maximum level 8 or 10 means?

    Tomaso , thanks for the link. That did the trick.

    I had posed a question in a previous thread whether I should get QR on my stem riser to get a flatter more compact fold when I can take my folder in. I made the assumtion that I would never lockup the folder.
    Being (un)naturally paranoid (living in NYC), if I determined that in my travels, I am forced to occasionally lock up my folder, any solution to secure the stem riser with a QR or would I have put back the original and current hardware (don't know what you call it). If buy the QR parts uninstalled, is it very easy to install or remove as needed? I might determine whether I leave the QR on or off, for an extended period of time depending where I am living at the time.

    Thanks for the link. Anyone know where to buy these in the US? I live in pretty low risk rural area and
    usually just lock while I am in a store for a few minutes. I use the same cable pictured a few
    messages back and find the springy nature of it a hassle to use. I will switch to the chain lock
    when I can find one.
