Motorcycle Chain Locks, BIGLUFU 3.3ft/100cm Heavy Duty Long Security Chain, Cut Proof 0.39 inch/10mm Thick Square Chains with 0.63inch/16mm U Lock, Bike Chain Locks for Motorbike, Scooter, Moped

This lock is incredibly heavy duty and works well for a great price. It’s a motorcycle lock, but I actually use it for my bicycle.

I've given this five stars but I'm going to be honest about my review. This may be a mishap on my end, but the length of the chain to me is not long enough. Let me explain, if you are wrapping this around a pole, and then your wheel. I'm afraid it's not going to be long enough. It may be for some depending on how big the pole is and this is where I misjudged it. I will say it is durable and heavy duty, it does work as it should. I like how the lock is set up on it. And they give you a lot of keys. So if you lose one just put the rest in your drawer so you'll have it as a backup. But so far no one's attempted to try to even saw it or try to break it. If you are traveling, you're going to feel the weight of it in your backpack for sure. I do like how it's got a cloth around the chain so it doesn't scratch anything up, but man are you going to get a workout carrying that thing around in your backpack. Overall I'm happy with my purchase, I do highly recommend getting a disc lock as well with an alarm system. It's nice to have that security and you can find cheap ones on Amazon that work really good

Love the heftiness and security this provides. Bought after someone tried to cut through my 1Up cable lock with wire cutters in a BLM campground outside Fruita one night (glad I had the 1up lock and not one of the my cheaper cable locks, but it was still compromised). They are not going to damage or get through this chain and lock without serious effort and noise. I hate thieves they are the dregs of society!

This chain is for serious security, it's really heavy duty and heavy.I doubt if any body is going to cut this in a short time.Nothing is 100 percent safe but just the weight and size of this chain is a deterrent.The lock on the other hand is cheap looking and does not look like it will hold up for very long,I suggest that you get a better more beefier lock.I hope you enjoyed my review...Lars

Works very well. Pretty sturdy and protects your bike from getting stolen. So far so good.

I like this a lot. I use it with a ground anchor bolted to the garage floor to prevent walk-off theft when we forget to close the garage door. I like that the hasp is large enough to lock on to the frame of my e-bike which, makes it quick to use.

The chain is great, very heavy duty… but the lock is poor quality. There’s been times where I thought it was locked and it just falls off. Other times it is locked and I spend 5-10 minutes trying to get it unlocked. Take the chain, buy a better lock…

Es buen producto se ve recistente

La chaîne a l’air de bonne qualité et plutôt lourde, le fait de pouvoir enfiler maillon rond pour plus de longueur est très pratique. Le cadenas n’a pas l’air très robuste et n’est pas très lourd, il parait plus costaud en photo. Je ne regrette pas mon achat.

Catena molto robusta, spessa e anche pesante. Ma è comprensibile dato che gli anelli hanno un certo spessore. La utilizzo per legare le biciclette in cantina.

This is an excellent visual deterrent to having your scooter or motorbike stolen. The lock needs to be treated with WD40 regularly, and be aware if you have painted wheels, the chain can chip your paint.

Excellent
