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.

Good luck very durable looks good and the locking mechanism is good but the sometimes it can be hard to put the key in almost as if it kinda gets stuck probably from user error

I love this lock its easy to handle and store away good product. Weight is acceptable easy to carry around, color also lovely, fit perfectly!

Good sturdy lock

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!

Easy to use, reliable lock, luckily didn't have a chance to test in action.

Great chain lock. Safe and secure

Sturdy, compact and fits in my sling bag nicely. Comes with two keys that work nicely.

cadena delgada para el precio

Devo dire che mi sono trovato bene. Sembra solida, lunghezza OK. Al momento nessun problema.

Gute Wegfahrsperre praktisch in der Anwendung, man hat sich bei der Herstellung etwas dabei gedacht, dazu noch zu einem sehr guenstigen Preis.

Product came a little late but the quality is ok.

This bike lock is an absolute beast. I don’t know if I bought a security device or adopted a small iron golem. It’s thick, heavy, and built like it was forged in the fires of Mount Doom by a blacksmith with anger issues. Honestly, it’s so tough I’m now worried someone might steal the bike and leave the lock out of respect. The look alone says, “I pity the fool who tries to nick this ride.” In fact, I’m 90% sure Mr. T would wear this around his neck as part of his ensemble, and no one would dare question it. Locks solidly, feels indestructible, and doubles as a great arm workout if you carry it too far. If you want your bike to stay your bike, this is the way. Absolute unit.
