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.

Lock is amazing and easy to use. It's a decent size and will chain up a lectric(<brand) XP lite e-bike so it's not small. functions great during winter too with the snow and salt and what not. Other than that very sturdy and highly recommend!!

Same as the pink one, its a great lock. we've had bikes stolen like crazy so now we don't. I love them

Strong, heavy duty chain, very convenient storage. Works great with my bike and my electric bike.

i planned to use it for my adult trike, however i have not received that yet. the lock is very long, has two keys and is very sturdy.

Haven't had any issues. The key cover, to protect against dirt etc, is easy to slide. I like how the company gives you 2 keys, in case you lose 1.

Much stronger than the cable we used on the first scooter that got stolen. So far, so good.

I gave this to my 8 year old son who rides his bike to school. It’s super easy for him to use and not too heavy.
