    • Great chain with peace of mind.
Size: 6.56ft/200cm x 10mm Diameter Chain with Lock
So far so good, I believe it is a good deterrent from theft. My motorcycle was stolen in the past and I feel secure knowing this lock is on my bike to protect me from potential thieves. I wish I would have gone with the 10ft chain, but this one works well. It is heavy which I like. Very sturdy and looks good. ... show more

    • Sturdy and intimidating to thieves
Size: 3ft/90cm x 10mm Diameter Chain with Lock
We've had this chain for a year and a half. It is attractive, holding up well, the cover over the chain is preventing damage to the bike, very pleased with that. I waited to leave a review so I could report on how it is wearing. It's wearing great, the included small U Lock is still functioning and not stuck, which is always good. The bike is stored in a covered but outdoor parking garage, so somewhat exposed to elements but not direct rain, just Florida humidity. We use the chain in 2 ways: out and about in a busy, downtown urban area that is notorious for bike theft. Had a bike stolen while we were at lunch here (only had a cable lock, never ever do that). No one will have time in broad daylight to cut through this chain in this urban environment, it is heavy heavy and will scare off any potential thief. You only need to be one of the more protected bikes downtown, as the thieves go for unlocked or cable locked bikes. The other use for us is locked up inside our gated condo garage. Twice our neighbors have had bikes stolen inside the garage, but not ours. Again, I think being one of the more secure set-ups compared to what else is available is making the difference for us. Could someone saw through the chain given enough time? Certainly, but it would take some time and tools. What we like is that our big U Locks, while they are lighter and really quick to pop on and off, super easy to use--- there are times that we don't have a good spot to lock them too, and they won't fit around a light pole or some other unique place. Also at home, the place we lock them too (a bolt in the cement wall), a U Lock wouldn't reach-- the chain gives you so many more options of how to lock even 2 bikes. But it is HEAVY, so heavy to work with, heavy to ride with, cumbersome to unlock it, wrap it around somewhere to travel with, finagle around to get it relocked. So if you don't have a specific reason to need the chain, a big enough U Lock is super easy. They say U Locks can be pried open, and cut open easier, so for overnight security, that is another reason we have both a chain and a U Lock. ... show more
