Titanker Heavy Duty Bicycle Lock Chain with Keys - 3 Feet Anti-Theft Lock for Bikes, Motorcycles, Doors, Gates, Fences, Grills (6mm Thick)

I recently purchased the Titanker Heavy Duty bike lock chain (3’) and I’m quite pleased with it so far. First of all, it’s much less expensive than other brands’ versions. Perhaps for the $5000 mountain bike I’d get the most expensive one out there, but for my older commuter bike, though a nice bike, the Titanker is sufficient.The lock itself seems very sturdy, encased in plastic with a sliding shield to keep debris out of the key slot. It comes with two keys that cannot be copied in typical key copy machines, so don’t lose your spare! You don’t have to turn the key to lock it, you simply plug the male end into the lock and it clicks shut, securely. The first chain link is solidly connected to the lock and the chain feels quite solid through the canvas cover. The cover is very nice for protecting your bike’s paint. The Titanker logo in white on the cover also looks similar to the more expensive brand’s so perhaps a thief would think twice about attempting to cut it.The chain is three feet in length so it can easily be secured around the rear wheel, the bike frame, and a solid object. My bike has quick release skewers so I remove the front wheel and lock it in as well(Helpful hint: I have a suspension fork so I carry small rubber booties to protect the wheel inserts from ground contact). I’ll also remove the seatpost and lock through the saddle rails if I’m leaving the bike for a long period. The chain is long enough to accommodate all those things. The chain is also very light despite its strength/length, so it’s not a burden in a backpack or wrapped tightly around the frame. My bike has a short seat tube extension above the top tube/seat stay junction so I wrap mine around there and it’s out of the way.Overall I am very pleased with all aspects of this lock so far, and will be purchasing a few more for friends.

The lock quality is very good and is waterproof as well. It does not weigh anything and is easy to install.

This heavy-duty chain feels incredibly sturdy with thick, hardened steel links that resist cutting. Easy to lock and weather-resistant—perfect for keeping my bike safe!

I would give it a five star if it came in a longer length. It is easy to open and I don’t need a key to lock it close.

This lock chain feels very solid and heavy duty. At 3 feet, it’s the perfect length for securing my bike, but it’s versatile enough for gates or other uses too. The keys work smoothly, and the lock mechanism feels sturdy.Gives me peace of mind knowing my bike is well protected. Great quality for the price!

Very heavy duty bike lock chain its a very good product

Heavy, durable, so far very good!

Nice lock. Bought one a couple of weeks ago, then another. . The length works good with me because you don't want it to long, only give thieves more areas to try to cut. I bought 2, separate times because I like the first lock one so much I bought a second one. If you need a longer chain, what I do is just link the two together. The quality is there, and I haven't had any issues. I'd buy again, for sure!!!! Also because there not to long, I can easily store or wrap the lock to my bike.
