Cable lock for indoors? Something thin, quick,and light?

Anyone able to recommend a very thin, lightweight cable lock? I've had no luck searching the forums and internet (since I'm basically asking for the opposite of a good lock hahaha).

The purpose: to quickly secure my folded bike when indoors. For example, when in a café/restaurant, I would use it to quickly lock the bike together + to the table so that I could go to the bathroom without worrying that someone might pick it up and run out. I would even use it when leaving my folder in my office, at parties, and anywhere else that is quite safe yet benefits from some basic theft prevention.

My criteria is light + fast/simple to apply (like 5 seconds to apply). Fast/simple also makes it subtle, which helps avoid the social awkwardness of acquaintances/co-workers feeling like I don't trust them (when the truth is that I want to minimize the need to question their trustworthiness).



Some Ideas/Thoughts:

-- a "retractable cable lock" sounds ideal, but the Amazon reviews suggest that they are too cheaply made and fall apart quickly

-- for traditional bike cable locks, it seems like 5/16in (8mm) is about the thinnest. And these cables almost always require wrestling with the coils to apply, requiring too much time/effort for what I want.

-- "Interlock" bike lock is appealing. But (A.) afaik it's still in development, (B.) adding seatpost caps to folders risks interferring with the fold, and (C.) I wouldn't be able to quickly ditch the added weight when sure I wouldn't be needing it.

Although I personally would use one of their new lightweight U's or a small Knog cable. That one above I could cut w/my Leatherman. I have trust issues and all three of my folders are expensive.

Cable locks are quite easy to cut with bolt cutters and I don't recommend them in general, but given your described use, they sound like they might be o.k.


I think you'll be better off with something like the Avenir cable lock and woudln't want to go much skimpier than that. It comes in three thicknesses, so you could get the thinnest/lightest, but it should be a bit more durable than something like the retractable lock mentioned above (I agree with the comment of the person who suggested the lock that it really isn't substantial enough for pretty much anything). If you are going to leave it unattended, I prefer locks with a key instead of combination; either should suit your purpose of running to the bathroom for a few minutes.

Cheers, Charles

Thanks, but unfortunately that is one of the retractable cable locks that has bad reviews on Amazon (here). The reviews chronicle how poorly-constructed the locking mechanism is and how the passcode combination malfunctions.

Thanks, I'll check out the Avenir.

Plastic coated cable, any length up to the whole roll and a piece, that is cast aluminum made to hammer shut
to form end loops on both ends .. + your favorite padlock..

Highly recommend this: https://www.wiggle.co.uk/abus-combifl...ble-bike-lock/ You can see it gets good reviews there, too.

I got it so I could let my self fall asleep on the train back after overnight cycles, when my folder was in the luggage area. On a previous trip, I'd left it in the doorway, so shook myself awake at every stop to make sure someone didn't pick it up on impulse when leaving the train. It's a cafe lock, for leaving a bike outside a cafe when you are never out of sight of it, and I'd happily use it inside a cafe on a folder under the circumstances described. For the record, I own two bikes, neither of which have been left locked outside ever in London where I live - yup, i'm paranoid.

This lock is very light, it goes in my saddle bag, there's always room. It's not very secure, of course, but people in cafes are generally not cutting through cables in full view of the staff - not even going near other's unattended property generally. And for use outside cafes? Compared to no lock, it gives you time to get outside if you see someone sniffing around your bike, where an unlocked bike could be mounted and gone in a second.

And it's better on a train than any other lock: the 90cm means you can find something to wrap it around. A nice, compact d-lock would likely not reach anything to secure it to.

I know exactly what you mean and why you would want a simple lightweight chain/lock. When I'm riding my Brompton and traveling as opposed to just strict commuting to work, I'm often riding to place that while I can bring my bike indoors into a more secure location, oftentimes it's not exactly overly secure and I might not know or trust the people there. The coat room at a hotel is a good example.

I used the prior version of this for a long time:
https://www.masterlock.com/products/p..._details/8122D

The only problem I had is that the cable was tightly wound, and it was a pain to uncoil and thread through all the spaces of the bike.

Something like this might work:
https://www.masterlock.com/products/p..._details/8418D

I bought a slightly heavier/thicker version for my bigger bikes, particularly if I'm going to be far away from a secure place like my office, to use in combination with my U-lock.

I've always waffled between a combination lock vs a key lock: which are you more likely to forget or lose: the combination, or the key? I've done both! C'est la vie!

I use very simple cable lock system for indoor locking only for my folding bikes. I even have one from the 1970s that works just fine for the indoor only locking purpose. The cables are like this one on the Sports Chalet webpage. They fit the bill just as long as I remember to only use them for just the select population of people who are not carrying any tools and might be tempted on the spur of the moment to grab and run or walk away with the completely unsecured bike.

Yep, understand that these will go through anything we've talked about here in under 3 seconds.

That said, there's the Python cable lock which might be of interest.

For situations like yours, I use a four foot non-coiling cable and a separate MasterLock 1500ID, which allows you to set your own combination and unlock quickly, one-handed, without even looking at the lock.

If 8mm is just too much, OnGuard offers a 5mm x 53cm cable which you might combine with a miniature combination lock or small aluminum body padlock. But seriously, you might as well use a zip tie.

I was wondering if its possible to get from either a marine supplier, or a mountaineering shop, a 450mm (or so) long, small diameter stainless steel cable with a spliced loop at each end; them all you would need is a small pad lock of choice.

How about the Knog Party Frank? It's not super thin, but they don't require much wrestling due to the thick coating. You can get one to match your bike too

The OP already visits cafes where he feels some need to lock the bike to the table, and has concerns that his co-workers might steal his bike from his office. I would think, though, that the more serious issue would be stopping on the spur of the moment at the market (new shipment of Indian mangos, on sale!) on the way home from the cafe. You'll use your little lock and cable - the bike will be all right, won't it, this time, for just a few minutes?

OnGuard U-locks start at $13 at my local Walmart.

For my tandem, which is rarely out of site - just long enough to order a beer and grab a seat - I have used a short cable, referred to in this link:

https://www.amazon.com/Planet-Bike-Bi.../dp/B000RY61F2

as a "bicycle seat security cable", with a small three number combo lock as used to lock luggage when travelling. It is definitely minimal security but enough to stop the walk-by opportunist. Anyone with a pair of bolt cutters in his backpack would defeat a more robust system. I just ordered a couple of folders and will use it when traveling by train if the bike is out of site or definitely on occasions in europe. It is very compact, light and better than no lock at all, although i have no illusions that it will stop a determined thief with tools.
