  • Solid heavy chain and lock
Size: 5ft/150cm x 12mm Diameter Chain with Lock
This is definately a heavy duty chain and lock exactly as described. While I didn't actually take a grinder to it, I have full confidence in it's ability to protect my ebike.

  • 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

Great HD chain. I really like the cover for the chain. Protects the item I'm securing and keeps it from getting scratched.

  • Heavy, thick (yeah, I know, that's what she said)
Size: 4ft/120cm x 12mm Diameter Chain with Lock
This thing is hefty. Maybe thieves in your area not only carry power tools but don't mind sitting there for 10-20 mins sawing away, but if not, this might be for you. I bought it and forgot I did until it arrived and this thing is massive. Links are at least twice as thick as a normal chain and it's just heavy. So heavy my first thought was that it would impact range and speed. It's just a big, thick ass chain wrapped in fabric and connected by a u lock, but honestly, do you need more than that? ... show more
