It is a cute bike chain, but it is too small chain bike in a lot of things ( 2 feet and half or 32 inch). I can only chain my bike in two things with it that is street parking sign pole or bike parking area.
I had better chain than this, and it was broken , and I was shocked.
I’m pleased with it because it Intimidation amateur thief, so they go on to an simpler bike.

Fantastic Price, will work nicely. Using for a motorcycle to go between the wheel spokes. If using for a bicycle you may want to get a longer chain.

This is a excellent tough chain. Simple to lock and doesn’t scrape up my bike. My only complaint is that it’s a bit too small. It kinda limits where I can lock up my bike.

This lock works like a charm. I can’t imagine anyone being able to break or saw through it. My only complaint is that it’s a small too small to fit around my (34″) waist, and so won’t fit around most huge telephone poles. But, when you find something sturdy to chain it to, it’s a monster.

Although this product is heavy and does its job, trying to lock the chain is very hard. The lock itself recedes all the way back, making it very awkward to loop the lock onto the chain. Its very frustrating to try to hold the heavy chain links together with one hand and try to lock it with the other while turning the key.
