The HENCH Bicycle Lock

This was a BSc Product Design project at Nottingham Trent University. This is the first prototype. I know the padlock’s the weak point, but further developme…

  1. There is always a weak point, here, the weak point is obvious and it will
    not last more than 30 sec for a real stealer… THE LOCK !

  2. not a bad idea for a mid security leve, but saying its really safe, and
    beyond that saying is the most secure lock is bullshit, how can this 4-5mm
    chain could be stronger than a descent u lock about 13 mm? and even more
    the 16-18mm ones? this chain could be cut easily by a bolt cutter, just use
    a nice one and youll see

  3. I’m not convinced. Bring it to Liverpool. I’m almost certain someone will
    cut through that. The angle grinder test didn’t look very fair. I’m sure
    that would get through it pretty well. It looks like a decent lock though,
    probably light, convenient, reasonably strong. The problem is with the
    ‘world’s most cut proof bike lock’ quote. It’s just not, at all. It
    shouldn’t be marketed like that but on it’s main benefits which is; it can
    be strapped to the bike, flexible, light and probably a mid range security
    level, which is fine. Not all locks are the strongest most cut proof locks
    in the world. Also, I’m sure there’s a weak point around where the padlock
    goes, let alone the actual padlock. Surely the thief would just cut the
    padlock. Good effort though.

  4. What utter balls, its just the strap that’s difficult to cut. Any bike
    thief will have the padlock cut or open in seconds.

  5. People will want to see real world tests for this to get off the ground. As
    it stands, I wouldn’t trust it simply because you’re attempts in the video
    don’t look very convincing.

    As said before, leave a half decent bike locked up in a major city centre
    and wait with a hidden camera.

    Not only will you nail a thief but you’ll have evidence it works and one
    hell of an advertising video. If it doesn’t work then back to the drawing
    board.

    Until then, you should probably stop making false claims as the
    consequences could be dire if bikes end up getting stolen due to people
    believing the hype. 

  6. But you can likely cut the fibres with a pair of scissors then attack the
    chain seperately therefore not fouling your cutting equipment, just attack
    the 2 seperate items seperately, still a top design though better than
    most else out there sadly.

  7. Interesting idea but clearly beta. Right now, someone with a bic lighter
    and a small pair of bolt cutters can defeat your lock (most Aramids are
    very weak against heat). Winding the kevlar threads through something like
    a Kryptonite NY Fuggedaboutit chain would help, but then you don’t address
    the main issue of the big chains which are that they are HEAVY. 

  8. i have to agree with some of the below comments, the attempts to break the
    lock are not comparable to what and how it is done in reality when someone
    knows the value of your bike and wants to take it

    that said I won’t bash you for the primitive nature of your video; you guys
    are clearly on to something, and it would behoove you take some advice from
    the diversity of cyclists/thieves commenting; it may improve your product
    and funding

    and with THAT said, if you just care to cash in with this demonstration
    alone, good luck, but I feel you are missing out, as I personally am not
    convinced you’ve fully thought through the potential of your idea

  9. Have some of the local bike thieves test it and see what happens. Talk to
    the police they should be able to put you in touch with a few to act as
    consultants. Its one thing to test in a lab environment, its another thing
    to test it in a real world environment. Remember they will also try to cut
    the lock as wells the chain.

  10. Aaaah, looks like you cut & pull away the wadding and then as Big Softy
    says, you have a 4mm hardened chain which is easily cut by any of the other
    tools.

    I admit that wrapping the chain in a casing makes it more portable but as
    for it being more secure… meh.

  11. People will want to see real world tests for this to get off the ground. As
    it stands, I wouldn’t trust it simply because you’re attempts in the video
    don’t look very convincing.

    Clearly not a super high security item, but enough to keep the honest people honest. Face it, if someone really wants your stuff, they’re going to get it. I was looking for a compact combination lock for my bicycle that could be quickly engaged while I go into a store or library for a few minutes. This fits the bill perfectly.

    Some clarifying comments:
    Set up of the combination is pretty much the same as other combination locks. If you read the numbered picture in the instruction book to figure out what button has what name, the instructions are very easy.

    The light is indeed removable. However, the light can only be removed when the lock is not locked. Therefore, using the light to see the combination dials is not possible, unless you have the foresight to take the light with you when you lock the items.

    I added a photo because the measurements on the site seemed wonky to me. 8 x 4.8 x 1 inches is just incorrect. The measurements are more like 3 x 4.8 x 1.

    I ordered this lock because I wanted a lock that was light enough to store in my seat bag. It works. This lock isn’t designed for serious security but it has a solid feel and a smooth operation that will act as a deterrent to the casual thief. Programming the 4 digit combination lock is a bit tricky but, once programmed, it works smoothly. 3 feet of cable is enough for most applications. I bought one for my wife as well and she uses it frequently and with some expectation of minimal security for short periods.

    Again, not serious security but if light and sturdy is what you are looking for give this one a try.
