  1. I have bike locks from Aldi (knobbly with plastic coating) and Lidl
    (longish steel cable). I noticed posters to this n.g. dismissing Aldi locks.

    They seemed okay for securing my bikes in a closed garage, but now that
    I have started commuting by bike and don't have a secure parking place,
    I may need better.

    I see D style locks mentioned. Are they all equal, or do I need to go
    for a brand name? Would I get a decent one in Halfords? (I normally have
    a poor view of Halfords, but a new one has opened here recently and it
    would be handy.)

    What is the weakness of the Aldi locks? Pickability or cutability?

    TIA,

    Jon C.

    Certainly not. Many on the market have been tested by cycle magazines using
    lock-breaking experts, and some can be broken much more quickly than others.
    Brute force is the usual method, rather than picking the lock.

    Mid to high price Kryptonite locks tend to be relatively OK. Hopefully
    other posters will recommend some cheaper ones that are also OK.

    Still, don't leave a good bike left unattended in a dodgy area for a long
    time. Otherwise you'll have bits nicked off it. This is why such crappy
    bikes are popular for commuting.

    Thanks. I forgot to mention, I have a length of (about 8-mm guage?)
    chain along with a decent lock that I used to use for my car steering
    wheel. Not too portable, but I could leave it at the hitching post.

    Any use?

    I suppose any £1,200 bike is vulnerable anywhere; my commute is 21
    miles, so I'm keen to use the best bike available. Also, car and bike
    theft would be relatively uncommon here (Donegal Ireland), but I suppose
    it takes only one thief.

    Thinking aloud ... maybe if I have a look around and ask nicely, I can
    get it indoors somewhere, where it will be both locked and out of sight.

    Best regards,

    Jon C.

    My bike gets left during the day (locked, but not with a specially good
    lock) in the office stairwell. Entrance to the building is by key-code, so
    it isn't a place where people can easily wander in off the street. The
    first week I left it there, I left a notice on it saying who I was and
    what room/extension I was in, and if it was bothering anyone to let me
    know. No-one responded and the security and estates people seem happy.
    There isn't a good bike shed on site, but I'm not sure how happy I'd be to
    leave the bike in a bike shed anyway.

    I'd imagine your cheapo locks will offer virtually no resistance to a
    pair of bolt cutters. You need a d-lock that's made of toughened
    steel. If I had a £1200 I'd be looking at a gold-rated lock (as might
    your insurer).

    Depends upon the bike shed I think. Offspring now at university. Where he
    keeps his bike is great, bearing in mind that no-where is guaranteed
    theft-free. Big bike shed - completely covered all sides & roof. Entrance by
    key-code and key-code is only given to those who have permission to keep
    their bikes in said secure shed. In the shed are sheffield stands and his
    bikes are locked to the stands by means of D-locks and cable locks. The bike
    shed is right outside the front door of his hall of residence and he can see
    it from his room window.

    Any lock with an exterior size of +22mm will be difficult to cut with
    bolt croppers. The key snapped in my lock, 22mm steel rollers around
    a central cable, light but strong, so that it would not open and you
    would not believe the amount of trouble I had finding bolt croppers
    that opened far enough to cut it at the local hire shops. I ended up
    with a pair about four feet long. Most bike thieves use very small
    12" sets for the cheaper cable locks.

    Theives don't just use bolt croppers. A large-diameter hardened steel lock
    won't /necessarily/ stand up to what they do for more than a few seconds, so
    it's worth doing some research on the make and model of lock.

    I had occasion to cut one of those, and yes, it was more of a pain than a
    simple D-lock for the tools I had available. I believe I did the main bit
    with a grinding disk on a drill. Portable angle-grinder would be the
    equivalent for serious thieves, but there's nothing much you can do about
    that.

    Favorite tools in my experience are

    1) Small bolt croppers
    2) Screwdrivers
    3) Wire cutters
    4) Biro
    5) Scissor jack
    6) Portable angle grinder

    Is carrying any of these without good reason an arrestable offence for
    being equipped for theft (apart from 4)?

    Plastic tubes can work as keys for circular locks like old Kryptonites used,
    apparently. I couldn't get it to work when I tested mine, though I got a
    new lock for good measure anyway.

  14. Thanks everyone; very informative. I even dusted off the 'old' bike for
    my ride to work today.

    And thanks for the mention of insurance --- what insurance? 🙂

    In addition to a stronger lock, I think that an indoors and out of sight
    location will have to be found; my place of employment is a university
    (institute of technology), so I should be able to find somewhere.

    There are bike stands in open view at the front of the building. I park
    my bike at the back door, in a semi-covered place designated as a
    smoking area. So there are people about most of the time. Unlike the
    main bike stands, quite a small proportion of the college population
    would ever pass by. However, as I said, it will take only one thief to
    spot the value of my bike. Am I right in assuming that bike thieves are
    unlikely to read u.r.c.?

    My current location is reasonably free of theft and quite easy going
    about security in an almost olde worlde way and so I have become rather
    relaxed compared to when I lived in large cities. I have a student from
    a faraway country and he reckons that some day a few of his compatriots
    will arrive and the place will be stripped as if by locusts. Not that we
    actually need foreigners to teach us about thieving.

    There was a story told about someone in our college who left a jacket on
    the back of a canteen chair; it was assumed lost along with the wallet
    and other pocket contents. However, the owner went for lunch a week
    later, to the same table, and there was the jacket and contents ---
    untouched.

    Best regards,

    Jon C.

    Or if you're stuck for a Biro of the right size (it has to be the same
    diameter as the key) then I've found that a rolled up business card
    works, or at least it did on one of those Kensington locks you get for
    laptops and they use a very similar lock. This caused my employer (big
    computer manufacturer) to do a serious rethink of how they secured
    laptops at the exhibitions/conferences. They changed to combination
    Kensington locks. Those took no tools to open, but it did take a lot
    longer (about 5 minutes).

    Just in case you're wondering, no I'm not a thief of any kind, I
    became interested in the security (or lack thereof) provided by
    various locks when I first read of the Kryptonite problem. The
    worrying thing is that it looks like about 99% of the locks out there
    (including those securing your home) can be overcome very quickly by
    anyone who feels the need.

    There's the remains of a bike that I pass on my homeward commute. It
    had been locked to some railings with a D lock that looks just like
    the one I bought from Wilkinsons for about 3 quid. Over the days I
    saw the usual damage from wheel stamping, then the wheels went
    completely. Last time I saw it I was very impressed as someone had
    clearly tried to remove the frame from the railings by picking it up
    and twisting. The two arms of the shackle of the lock were twisted
    around each other 360 degrees but it was still in one piece and the
    locking mechanism hadn't popped.

    Kryptonite recalled all their susceptible locks because of it, others
    may be out there.

    Do you know how old the relevant locks are? One of my bikes is routinely
    secured with a Kryptonite lock and I'm now concerned.

    Your lock will be the relevant type if the key is tubular.

    Ah.

    Having looked on their website I cannot find any details of the recall.
    As the lock in question is several years old, would it be covered
    anyway?
