Security Chain Lock [Sold Secure Gold] – 4ft Long Bike Chain with 4 Keys – Heavy Duty Bike Lock 0.33" – for Bicycle Ebike & Motorcycle – Motorbike & Scooter Anti Theft

This bike lock is very good! As somebody who's new to the whole bike world, finding a lock and what would prevent theft was pretty difficult.One thing to understand if you're in the same boat I was, don't buy cheap locks. Don't buy weak locks either! Chain locks are probably one of the best you can get, unless you plan on getting those anti-angle grinder locks that cost easily half the price of your bike, these heavy-duty chain locks work very well!It's less about how easy it is to break into, but rather how good of a deterrent it can be. When a thief is carrying around some bolt cutters, he's going to be looking for the easiest lock to cut through. He won't spend 4+ minutes gnawing away at your 0.33" chain lock just to get your bike, especially at the risk of getting the police called on him. If you live in a busy city like Chicago, New York, or London, you're definitely gonna need some more serious security.For me, this lock is perfect. I use my bike to commute around my city. I live in a populated area that has a decent amount of crime, just outside of Detroit, sort of known for theft. I leave my bike outside the gym (nobody wants to steal a bike from a gym, let's be honest) for about an hour, and it's completely fine. I'll go shopping at my local grocery store for about 15 minutes and it's completely fine.If you're in a similar situation to me, a city (decently small, but larger than 50,000 people) and has a reputation for theft, then this is a totally perfect bike. BUT! By no means is this secure enough to use to leave outdoors for more than 3 hours, especially overnight. In that time, any guy can run back home, grab his angle grinder and a few blades, and get through this lock in probably 3-4 minutes. If you absolutely NEED an overnight lock, I suggest getting some that are made out of anti-angle grinder materials. They'll run you $250+, but will make it worth your while, as it'll gnaw away at the perp's saw blade before it'll gnaw away at the lock itself. Either this, or you can get one that plays a loud alarm when moved.Now, one of my only complaints about the lock is the plastic housing on it. The part that holds the locking mechanism is a cheap sort of plastic that will chip away every time that it hits the pavement. And, if you're clumsy like I am, you're bound to drop this thing on pavement hundreds of times. Even just dragging it against the pavement is going to make it look like it escaped a tiger's den! This isn't that big of a deal as you can just be more careful with it, and so far it hasn't brought any issues as far as I'm aware.

Have been using this lock for a bit over a year now. I live in a small city and have not had any issues using this as my primary lock for an E-bike though I also use a folding lock as a secondary/helmet lock and have a motion sensor alarm. I do believe this thick, heavy chain is a deterrent and would tend to make someone who is inclined to steal a bike look for an easier score. Just be careful not to drop the lock with the key in it as the weight of this chain hitting concrete can cause the key to bend.

Solo le doy 4 estrellas por lo práctico I cómoda y fácil manejo. Pero lo bueno está en que no la corten y me roben mi bicicleta Eléctrica hasta entonces le daría las 5 estrellas y mas esperemos que sea SEGURA.

I was very impressed with how beefy and solid this chain lock is. I now feel secure that I will find my bike where ever I secure it with this lock.

As others have mentioned, this is a hefty lock! It’s heavy and pricey and the locking mechanism doesn’t always turn without some wiggling, jiggling, cajoling, and occasionally threats. I never struggle to unlock it, but the rubber creeps up the chain section and makes getting it locked the very last straw if you happen to be running late.That said, I very much still have the bike for which I use this lock and I have always been able to find places to park it because the lock is so versatile. Bike racks, trees, pipes, sign posts, hub cap spokes, a sleeping camel - this chain can wrap around just about anything if it stays stationary long enough and still have your bike waiting there for you when you get back.

This thing is a beast! Very strong and heavy duty. Will take someone a long time to try and cut through it. Can the lock be picked ? I think so but not easily. Don’t get a short one you need to have long enough chain to go around bike and whatever your locking to.

Chain is a little on the heavy side but it is worth every penny. I able to lock up two bikes with ease.

I had used a cable lock previously but learned how easy they are to cut. This chain is beafier than the cable lock and should be able to slow up a thief. At 5 lbs. I can still carry it in my bag on the rack of my electric bike. Now I use this heavier chain lock along with my cable lock for the front wheel.

Chain is long enough for my use, heavy but that was expected, very happy from purchase, time will show if it is safe enough :) (as for now would reccomend !)

Chaîne bien évidemment un peu lourde mais de très bonne qualité : l’enveloppe en toile est résistante et la serrure n’est pas en fer blanc. La longueur permet de faire le tour d’un beau poteau de 20 cm ce qui fait la différence quand les places sont rares.

I'm a bicycle courier and often have to lock my bike up in places where it's not. otherwise, so easy to lock it to an immovable object.But, I've been able to do so with this (rather than a D-lock, or the like). It has longer length and and a good balance between locking length/diameter and strength.
