    Thanks for all the advice - thanks @Tangoup51 and @vickster in particular.

    In the end my doubts about button cells meant that I passed on the alarm lock (for now - may go that way later) and I have other alarm things I could secrete in my tourer's panniers.

    So since delivery is free at the moment, and returns also, I have gone for the Mountain Warehouse lock as suggested by vickster. Some quick measuring suggests that it might fit very snugly round the 26inch wheel Exped bike's front wheel and a bit of the frame, so I could use it like I use my light Decathlon cheapo special on my London town fast bike.

    Have a vague memory that I have seen this lock in Mountain Warehouse shops and been none too impressed with it but it may possibly be ideal for my intended use.

    Have no fears folks - it won't be used as a primary lock in London. :smile:

    Will try to report back.

    Thanks again.

    @Blue Hills I'm Glad you made a choice & I hope it serves you well, that said, the same way you are hesitant of button cells is the same way I am hesitant of cheap D-locks, I wish it was pessimism, but alas, it was from my own experience that made the judgement call.

    My Key had snapped in the cylinder of a cheap D-Lock I bought from amazon, all the cheap low-end d locks are usually the same Chinese import but with a different logo slapped on it. - The key snapped because the pins in the cylinder were seizing up (From weather?) Hardly put any force in the damn thing, the key was made of cheese, once more it hardly saw rain use. Just cold conditions and light use for about 6 or 8 months.

    Credit to my luck (and rather my stupidity) i didn't lock it through the frame on my mtb, just the back wheel when the key snapped, so I was able to carry the rest of my bike home and then arrange transport to come back much later to "get" the rear wheel.

    I tried digging the key out of the cylinder so I could use my spare key, but it wouldn't budge. In the end I couldn't be bothered, so I resorted to bolt cropping it the U lock. Medium sized bolt croppers & it went like cheese. - A little bit of resistance at first but then it just Glides through. Really surprised.

    I reckon it was made out of mild steel. Nothing hardened at the price I paid, wasn't too upset about the whole experience but I realised if the key had snapped while the frame was locked up too, it'd of been a much worse experience.

    Anyway, I presume its the £5.99 mountain warehouse lock that vickster proposed? I recognised it on Amazon a ways back, i was looking at it too.

    Take a look at the reviews here, they are more indepth than on the mountain warehouse website.

    Update

    After some boring delivery muck-ups involving an honest mistake on Mountain Warehouse's part and some par for the course bungling from Hermes, the lock arrived. Will try to take it back as:

    1: Despite the measurements given on the web page it appears to be no bigger than my trusty £3.50 (albeit mysteriously discounted) Decathlon special, so it is of no use for my expedition bike. Pity Decathlon don't do a slightly bigger version of it.

    2: It is super shoddy, even for my intended use. Not a big criticism of Mountain Warehouse as they do some decent clothing at their "normal half prices"

    I would use the Kryptonite thing I referred to above but am worried by reports of it locking onto your bike.

    The search goes on, but I think I'm looking for something which is hard to find.

    Sorry to hear it's been rough sailing, you handle it with alot more patience than I would :okay:

    That said, what did you mean by "reports of it locking onto your bike"

    Apparently it can be hard at times or even impossible to unlock. Which could be irritating to say the least. Or possible force you to leave your bike for longer than you planned, possibly overnight in a dodgy area, making it a sitting duck for leisurely thieves. Not what you want from a lock. :smile:

    So still looking if anyone has any suggestions - cheap, medium size, light. Moderate security OK.

    Many locks attract similar complaints. Sometimes because the owner has used a cheap spray lubricant in it that leaves a sticky residue. Does that one have more than usual?

    I don't know mjr, perhaps I just took fright because it seemed such a serious problem.

    On the subject of lock lubing, can you say more?

    I rarely lube locks and when I do I use gt85 or wd40, the latter in particular seems to work fine on my sometimes problematical door locks. I know some folk recommend graphite of some sort but that sounds too complicated. Thanks for your encouraging words, I may reconsider the kryptonite.

    You need not worry about the locks seizing (Among other quality control issues) if you're buying a lock from a reputable source and from an acceptable price point.

    The only locks you should be hesitant of, are the unnamed, unknown, cheap ones. that have no one to back their standards.

    The one you posted there is fine, it's cheap but not cheap enough to be of concern and onguard are reputable.
    Though, that clocks in at 930 grams. I do think it's pretty heavy compared to the prior options.

    As of your cleaning concerns, WD40 is acceptable, it's a solvent so it eats and dissolves Rust and Grime that'd otherwise cause your lock to seize, actual lubricants (such as Lithium grease sprays) Will Attract dirt and worsen the problem as metal-on-metal wear & grime occurs. -- it'd be attracted by the lubricant, not the solvent.
    IMO Locks don't need lubricating, they just need degreasing, WD40 is more than acceptable for that.

    Anyway, as you're trying to keep your lock criteria small, lightweight and secondary, I still maintain You're going to have trouble finding those criteria with D locks, as almost 99% of the time D-Locks are Primary locks, so they're big & heavy.

    I use an OnGuard https://m.ebay.com/itm/OnGuard-Bull...lok-Series2-/291513341067?txnId=1523781178019 and it was the best I found for the price. You can order it with or without the cable, which I loop around my wheel and to the fence at work. The locking mechanism is very nice and hefty, doesn't move at all, and the keys seem well made. The mounting thing that came with it was useless as with my bike no matter where I tried to configure it on the frame it wouldn't work, but I just toss it in the pannier.

    Also I have always used Wd40 on locks, even the old shed lock that gets all weather, and never had problems. It is used for freeing stuck bolts/hinges/mechs so since it gets rid of rust and grime buildup we use it on everything at home! If you had a lock that wouldn't unlock I would try that.

    Thanks draconis
    Yes i have an onguard lock. I rate them.

    The one I bought for this application in the end was also an onguard, the Neon listed above (mountain warehouse thing is going back). The saving of half a kilo over my primary lock is nice. It's a bit long for what I need it for though so not absolutely ideal.

    So yes i recommend their locks.

    Agree with you about WD40.

    Someone at work does this all the time on the stands outside and it gives me a feeling of dread every time I see it. The bike is a Temple that's always kept immaculate so not a BSO by any stretch and seems to be looked after so why would they risk it like that? There are regularly dodgy characters on this road stealing bikes or snatching phones.

    Have you mentioned it to them? It is possible that the problem hasn't occurred to them. I assume that the Putney person was oblivious to the fatal flaw. I can only hope that thieves were as well, unable to process what their eyes were telling them.

    I've never seen who rides it as they're in another building and arrive and leave after I do. I could leave a note but i always worry that'll actually attract attention to the bike and the lock which wouldn't be ideal.

    I wouldn't use a cable lock full stop. The only D-locks I would use are Abus. I am prepared to carry a heavier lock if I feel it necessary and so often carry an Abus Granit X-Plus either the 230mm or 300mm shackles, depending where I am going. I also have these lesser specced Abus D-Locks but still gold rated.

    I am looking at getting one of these for when touring https://www.cyclesurgery.com/p/abus-bordo-6000-folding-lock-P5240003.html?colour=180

    If you really value your bike and don't want the hassle and grief of losing it then buy a good lock.
