    • Great bike lock!
Robust, protected, and pretty portable. It's a heavy chain, for sure, but it is easily wrapped around any portion of the bike, or even used around the waist or across the body if need be. The cloth chain cover is extremely thick and rugged, and I have no doubt that it will prevent anyone with a boltcutter from tampering with it. The black doesn't seem like it will fade, and you can't pull the cloth back from either end of the chain, so it's adhered pretty nicely. It's super easy to use, and there's even a little door over the lock inlet you can adjust from open to closed to protect it from the elements. ... show more

    • Sturdy and affordable
Locks easily. I really appreciate locks that do not require the key to lock, saves some time. It seems sturdy enough but keep in mind these are still just chain locks and are not the most secure locks. Good as a second lock, good for quick trips, or somewhere that's mostly safe like grocery stores. You can easily attach it to your bike frame and unlock it when you get to your destination. Really easy to travel with it. ... show more

    • Great for bikers on-the-go!
This is the BEST bike lock in the world. The key is sturdy and durable, I've never had an issue with the lock. I had someone attempt to pull the lock apart when I had it clipped together and it held up astonishingly well! The inner chain is flexibly enough to adjust to whatever I lock my bike to, even if I'm just looping the lock through the weel and the frame of my bike while on a trail. 10/10 purchase! ... show more

    • Titanker Heavy Duty chain lock for bicycles
Review Image by Crockett Henley
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. ... show more

    • Excellent in bad weather
My lock is outdoors even in the winter with snow and ice and it has handled it very well. It is also quite nice having two keys.
