Features

  • Secure & Portable: The key can only be pulled out after the bike chain lock is locked, which prevents the key from being lost. Titanker bike lock comes with 2 keys. You can take one of the keys to use in daily life, and you can leave another key at home in case you accidentally lose one
  • Heavy Duty & High Quality: With 10mm thicker security heavy-duty chain links, our bike lock is made of heavy-duty steel known for its cut-resistance. Lubricate the bike chain lock hole and keyhole regularly, this will prolong the lock's service time
  • Protective Cloth Sleeve & Dust Cover: Chain is enclosed in protective cloth sleeve, which effectively protects the bike lock chain from rusting and scratching
  • Safety Tips: Never leave your bike locked outside for long periods of time. Especially in high crime areas. No bicycle lock is 100% secure

  • Simple and easy to use, sturdy, well made!
Color: Black-10mm Chain
EDIT: I would still buy, It’s been over 6 months now (EDIT: about 6+ months in and the nylon chain cover has become detached from one end of the chain. It’s not a huge deal or very noticeable at all and can be glued back in easily. Highly recommend for people who don’t want to #1 overpay for a lock, 2 you’re in a large city or on campus and NEED a warranty if you’re parking in unsafe areas often Kryptonite has warranties but I don’t live in a large city and don’t park my bike on university campuses or downtown often and have faith in this chain. I would maybe bring extra locks if I did go downtown just in case for front wheel but the 12” chains are an excelllllent size for preventing thieves from snapping the lock as easily for a great price. Also I love the key feature. It works great and has a backup. Unless you come across a lock picking expert or someone with a giant saw you’re pretty safe imo. The locking mechanism is great and so simple to use. It unlocks very easily with just a twist. The lock cover is great for dirt and debris but I usually wear my lock cover easily around my shoulder or waist or sometimes my bicycle it’s not too heavy and a perfect length to lock my frame and rear tire. It’s also quite thick to deter any thieves, encased in nylon which prevents any scratching, and another deterrent (edit: one side of the nylon has detached but not the end of the world). I would definitely buy this again. It’s not too big take Carrie and not too small to not deter a criminal. It’s perfect compared to the insane price of some locks. Some of those lock costs 10-15% of my bicycle. I also recommend buying an apple AirTag hidden, cheaper combo than many kryptonite locks. 80-90% of bicycles are never recovered. ... show more

  • Excellent lock! Until I dropped my bike 😅
Color: Purple-8mm Chain
Lock is incredibly thick took me about 10 min with the grinder to be able to break through the lock. So for toughness I 💯 recommend it. I leaned my bike over a couple days ago and realized I had dropped my super73 on top of the lock and bent the metal inside the lock itself and the key wouldn’t release it. So my only option after that was breaking it off 🥲 definitely would buy again! ... show more

  • Good lock
Color: Black-8mm Chain
It’s a good lock. Chain feels heavy. Used it to chain my bike up at work then we moved office buildings. But it has served me well and I keep it in my bike to be used at anytime needed. Has served me well.

  • Falls apart within months. - Edit: Manufacturer sent a replacement
Color: Black-8mm Chain
Bad quality lock, the locking/unlocking mechanism is not consistent. I've had the lock for around 8 months now and it's begun fully failing. It has not been working as intended for most of its use so far. Edit: The replacement lock has arrived and it works great, just as I remember the original working at first. I hope that it holds up and that the first one was a fluke. I’ll further edit this if the replacement begins to break as well. ... show more

  • Good Quality
Color: Black-8mm Chain
Bought the lock for my motorcycle cover. Chain is thick, but fits through the wheels. Kets are a little cheap, but work well. Satisfied with the product.

  • Heavy Duty

The chain appears to be unbreakable. I would totally trust it with my bicycle.

  • Just as described
Color: Blue-6mm Chain
Lock is sturdy which makes me feel comfortable when locking up my bike on city streets. It also looks cool. Glad I bought it. The length I went with works well but I would recommend going longer if you are locking up multiple bikes!
