Sleeve back. Bare core. Cuff cylinder.
Every scooter chain hides its thickness under fabric. Here is ours, unwrapped.
Built for scooter geometry, not bike frames - the sleeve is there to protect your finish, not to hide the core, and the chain stays flexible enough to close through a wheel or around a stem.

You do not need another lock. You need one you can believe.
The rack outside class · every weekday
The wrapped mystery chain
Thinner than advertised“The chain is a lot thinner than I thought it would be”
The cable lock
Cuts with pliers“Cable locks are so easy to cut with even a set of pliers”
The bike U-lock
Will not reach“The U shaped locks are quite difficult to place”
Carrying it inside
Works until it does not“Just take it inside instead”
None of that is on you. A 5mm core under fabric and a shackle shaped for a bike frame were never going to hold a scooter at a public rack - and nobody should have to carry a 40-lb machine into a lecture hall to feel safe.
A shackle spans a gap. A chain closes around whatever is there.
The chain is sleeved and flexible, with an identical keyed cylinder housing at each end. It closes on itself around irregular geometry, so one loop captures both the scooter and the anchor it is tied to.
1
Through the wheel
Thread the chain through the wheel, around the fence, close both cylinders.
2
Around the stem
Wrap the stem and the same anchor, bring the two cuffs together, key it shut.
WHAT YOU ARE LOOKING AT
- Sleeved chain - flexible enough to wrap a wheel, a stem or a deck
- Twin round cuff cylinders - one at each end of the chain
- One key opens both ends, so there is nothing to memorise
“It is like a giant pair of handcuffs with rubber on it with a chain in between”
How owners describe the form factor
5:40pm · the cafe he used to skip
You bought it to move you. Somewhere along the way it started owning you.
It gets folded and carried up two flights into a lecture hall, where it leans in the aisle and someone trips over it. It comes into the office. It comes into the shop. It goes wherever you go, because leaving it outside has never felt like a real option.
So you skip the cafe across the street. You take the long route that ends where you can watch it. The machine that was supposed to give you your city back has quietly been taking places off the list.
The point of a lock is not the lock. It is the places it gives back.
What it is like to own, on the ordinary days.

From rolling up to walking off is maybe fifteen seconds. I do not think about it anymore.

My last chain chewed the paint off my stem within a week. This one has been on the same deck since March and there is not a mark on it.

One key for both ends. Sounds small. It is not, at 6am in the rain with gloves on.

Racks, poles, a wrought iron fence outside the bakery. It has found something to grab onto everywhere I have stopped.

Picked it up and knew. It is heavy in the hand, and that is the entire point of buying one.

It has lasted, it has kept the scooter safe, and it still opens and closes the same as day one. Yes it is hefty. I stopped noticing that after a week.

The questions riders ask right before they buy.
Answered plainly, including the ones where the honest answer is a tradeoff.
There are two routings and most scooters take at least one of them. You can pass the chain through the wheel, or wrap it around the stem or frame, then bring both cuff cylinders together around a rack, pole or fence.
That flexibility is the whole reason a chain works here where a rigid shackle struggles. Before you order, check that there is a hand's width of clearance around your stem or through your wheel, and you will be fine.
Each end of the chain is a keyed cylinder housing, and both take the same key. Keyed closure is what riders in this category consistently report holding up against pick and pry attempts, where cheap dimple mechanisms do not.
On seizing, the honest answer is a warranty rather than a promise: CuffLock is covered by a 1 year warranty. If the cylinder stops working properly in that window, you are covered.
The exact key count is printed on the packaging and in the product details on this page. Whatever ships in the box, both cuff cylinders are keyed alike, so every key you receive opens both ends.
If a key is missing from your order or you lose one, contact us. The 1 year warranty covers hardware faults, and we will sort a replacement rather than leave you with a lock you cannot open.
It has real weight, and we would rather say that here than have you discover it on the doorstep. The weight is the metal. A chain light enough to forget in your bag is a chain thin enough for a thief to forget about too.
If you are riding a few miles to class, work or a delivery shift and parking in public, that tradeoff is the right one. If you need something featherweight to slip in a jacket pocket, this is honestly not the lock for you.
No, and that is exactly what the sleeve is for. The links are covered so that metal never touches your deck, stem or paint while you are threading the chain through a wheel or wrapping it around a frame.
Owners of covered chains say the same thing in review after review: the covering is what lets them wrap it tight without wincing.
