    The One Thing that's Missing on your Great Bikes!

    Dear Dahon,

    I acquired an Impulse P21 in November and am very pleased with it.

    One very important thing, though, is missing on all your bikes: a really

    effective anti-theft device. Couldn't you design something that would
    somehow
    make it impossible for an unauthorized user to make use of your bikes?
    I'm
    thinking along the lines of something that would make it impossible to
    fix the folding mechanism into riding posture. Without the special key
    or lock
    the bicycle would refuse to stay rigid in the middle. That way no extra
    weight
    would be added, as is the case carrying around a monstrous u-lock, and
    it
    shouldn't interfere with the folding mechanism.

    It's just that they're great bikes and quite pricey and way too easy to
    steal.
    I'm reluctant to take my bike on tour with me, even though I bought it
    for that
    purpose, because I don't want to let it out of my sight!

    Yours sincerely,

    Elisa Francesca Roselli

    Yours sincerely,

    With a folding bike you can often take it with you and either keep watch
    on it or leave it somewhere a lot more secure than in the street. That
    will not work all the time, so a lock is necessary. There's no doubt it
    is frustrating to get a decent lightweight bike and then have to carry a
    very heavy lock to secure it.

    However, the problem with your idea is that although it might make the
    bike unrideable to a casual thief, it does nothing to prevent it being
    thrown in the back of a vehicle and taken away to be fixed up later.
    It's not really enough to just make the bike not work. It is far better
    for it to be anchored to something that prevents it being removed at all.

    I've done quite a lot of touring. It's not possible to avoid every risk.
    Carrying a lock is a choice, how much you use it is a choice, and
    sometimes you just have to choose whether to leave the bike and your
    luggage somewhere while you wander off for a while although there is
    nothing to which the bike can be attached . In some places I am quite
    relaxed about doing that. In other places I would not dream of it.

    Yeah - something incorporated into the frame so that the bike can be folded
    around a lampost/sheffield stand and cannot be removed without cutting
    through the frame. It would be fairly light because the locking mechanism
    is the only thing that needs to be tough - the rest of the lock is the bike
    frame so cutting through it would defeat the object.

    Why would it be less of a target? Even if the person doing the stealing
    isn't aware that it can't be ridden, it may still get stolen. A lot of the
    time theft is the result of opportunity. Having a heavy U-lock on it may
    deter a lot of would be bike thieves from bothering. Having a non-obvious
    theft deferent would be ineffective, IME.

    I've never locked my Brompton up - I just take it with me and have never
    yet been refused entry from supermarkets to courts to the poshest
    hotels. The problem with your idea is its too easy to just lob it in the
    back of a car and sort the problem of the frame out later - they do that
    with full size bikes and a truck. What you do need is a different type
    of lock because folding bikes generally do not have a conventional
    diamond frame to put a lock through.

    It is a universal law.

    weight of bike + weight of appropriate lock = constant.

    In the real world you want to get off your bike for 2 minutes to buy a
    paper. Locking it can be one pain in the [censored] (assuming there is
    anything to lock it to and you are carrying your 2kg U-lock).

    All else being equal, if there is an unattended bike which you cannot
    ride next to one you can, odds are that the one you can ride will be
    stolen.

    It should be simple to implement an integral locking system in a folding
    bike so why not. Its far from a perfect security measure but why not
    add it anyway?

  10. It would be slightly useful against a thief who would jump on and ride
    off, but not useful against someone lifting the bike up and putting it
    into a vehicle.

    With a Brompton you can remove the thingees that hold the steerer and
    the frame together, and take them with you.

    On a bike with S&S Torque couplings, you can secure the frame around a
    post or tree, and you'd need a tool to get it apart (though I suppose
    Vise Grips (TM) might also work).

    I forwarded your suggestion on to the VP of Dahon (and son of the
    founder), since he'd be a better person to answer this than the UK
    sales office. If he answers me, I'll post the reply, but he may send
    you an e-mail directly. He's a really good guy, I'd be surprised if he
    doesn't respond.

    Interesting. The bike is left for 2 minutes. Within that time, someone is
    fishing through the unattended bikes to see which can be ridden and which
    can't (a big U-lock would tell them quickest). I can see how someone
    getting on a folding bike and finding they can't ride it might foil the
    attempt....but it won't stop them from putting in the back of a truck if it
    can be easily moved.

    Cost and effectiveness, I would guess. If it's ineffective as a deterent,
    but gives the owner a false sense of security (as did the Krypton U-Locks),
    then what happens later?

    Perhaps this could be an option they will offer their customers.

  12. NOTHING will make a bike completely theftproof. A locking system that makes
    theft "inconvenient" may deter a casual thief, or cause him to pick a
    different bike, but if it provides the owner a false sense of security, it
    may be worse than nothing. For a Dahon folder, I think a lock that holds
    the bike half folded (frame forms a 90 degree angle) would make the bike
    impossible to roll, and difficult to put in a trunk or back seat of a car.
    Once you start to consider what a thief with a truck can do, you might as
    well give up. I once heard of a theft where a flatbed truck was used to
    haul away a rack with all the bikes locked to it. (Could be an urban
    legent, but it's possible.)

    An acquaintance had his motorbike stolen from the halls of residence car
    park on the first day of term. It had been locked with a chain, so
    presumably it had been loaded onto a pick up truck and driven away.

    On a couple of occasions I cycled by Brompton to my local swimming pool.
    I didn't take a lock, but removed the tube clamps and put them in the
    locker along with my clothes. I never felt comfortable doing this as
    there was nothing to stop someone else carrying it out with him, though
    I doubt that any swimmers drive to that particular pool. One alternative
    was to ask the staff to keep it behind their desk, though I don't think
    they'd oblige.

    Now I take my touring bike, which has an Abus Granit on the frame, and
    attach it to some railings outside, which I feel is more secure (or am I
    risk compensating again?).

    It would have to be bloody obvious to the clouded vision of the usual
    deranged thief. I once fitted one of those wheel locks that fit beside
    the brakes and thrust a bar through the spokes to stop the wheel going
    round, with the idea that it would be handy for just popping into a
    shop kind of stops. Withing a few weeks of occassional use My bike was
    once carried away about 50 yards by a thief who then gave up and
    abandoned it, and another time suffered a damaged spoke.

    I decided to give up the lock before my bike suffered the "thief's
    revenge" of having my wheels stomped out of shape.

    I had similar difficulties on a motorcycle whn using a non-obvious
    lock. In that case I put a notice on the petrol tank explaining
    things. Fortunately these days most thieves can read.

    Just unscrew one or both of the clamps completely and take them away
    with you.

    (Though mine never leaves my sight or the inside of a locked room.)

    Which, to some degree, explains why they steal.

    I got a reply from the VP of Dahon, hopefully Elisa got the same e-mail.
    No real surprises....

    "Thanks for your feedback. That's a good idea but you know, if you left
    your bike folded somewhere, locked with such a mechanism and nothing
    else, somebody would still steal your bike. They would get home and have
    trouble using the bike but your bike would still be gone. So you'd still
    need to lock your bike to something solid, leaving you in the same
    situation as before - needing a heavy lock.

    With a bike like the Impulse P21, the reality is that you just need to
    take it with you or at the very least put it in a storage locker or closet.

    Happy cycling!"

  20. I agree that nothing would make my Dahon theft-proof, but I still think that
    research into really lightweight, ingenious anti-theft devices that break
    with the ball-and-chain model is far from finished and would benefit all
    bikers.

    One upgrade that I have found available for Dahon and may consider is a set
    of pedals which, instead of folding inwards towards the bike, are simply
    removed when the bike is at station. They are said to be easy to snap back
    in again when back in motion. This does mean walking around with a set of
    muddy pedals in my handbag, and of course it still doesn't prevent someone
    carting off my bike in the back of a car. But it could be a short term
    deterrent to thiefs who would want to ride off with it.
