Review: Great lock, very heavy! - This bike lock is very good! As somebody who's new to the whole bike world, finding a lock and what would prevent theft was pretty difficult. One thing to understand if you're in the same boat I was, don't buy cheap locks. Don't buy weak locks either! Chain locks are probably one of the best you can get, unless you plan on getting those anti-angle grinder locks that cost easily half the price of your bike, these heavy-duty chain locks work very well! It's less about how easy it is to break into, but rather how good of a deterrent it can be. When a thief is carrying around some bolt cutters, he's going to be looking for the easiest lock to cut through. He won't spend 4+ minutes gnawing away at your 0.33" chain lock just to get your bike, especially at the risk of getting the police called on him. If you live in a busy city like Chicago, New York, or London, you're definitely gonna need some more serious security. For me, this lock is perfect. I use my bike to commute around my city. I live in a populated area that has a decent amount of crime, just outside of Detroit, sort of known for theft. I leave my bike outside the gym (nobody wants to steal a bike from a gym, let's be honest) for about an hour, and it's completely fine. I'll go shopping at my local grocery store for about 15 minutes and it's completely fine. If you're in a similar situation to me, a city (decently small, but larger than 50,000 people) and has a reputation for theft, then this is a totally perfect bike. BUT! By no means is this secure enough to use to leave outdoors for more than 3 hours, especially overnight. In that time, any guy can run back home, grab his angle grinder and a few blades, and get through this lock in probably 3-4 minutes. If you absolutely NEED an overnight lock, I suggest getting some that are made out of anti-angle grinder materials. They'll run you $250+, but will make it worth your while, as it'll gnaw away at the perp's saw blade before it'll gnaw away at the lock itself. Either this, or you can get one that plays a loud alarm when moved. Now, one of my only complaints about the lock is the plastic housing on it. The part that holds the locking mechanism is a cheap sort of plastic that will chip away every time that it hits the pavement. And, if you're clumsy like I am, you're bound to drop this thing on pavement hundreds of times. Even just dragging it against the pavement is going to make it look like it escaped a tiger's den! This isn't that big of a deal as you can just be more careful with it, and so far it hasn't brought any issues as far as I'm aware.
Review: Top Notch, 1/2 the Price. - Better quality than expected for 1/2 the price of the leading brand. It's nice and long, sturdy, keys work easily. Note that this is a bulky chain but that's why you are buying it. I trust my bike when I need to walk away and out of sight. That is all I need to say.

## Features

- 𝗦𝗘𝗖𝗨𝗥𝗜𝗧𝗬 𝗙𝗜𝗥𝗦𝗧, 𝗡𝗢 𝗘𝗫𝗖𝗨𝗦𝗘 𝗚𝗜𝗠𝗠𝗜𝗖𝗞𝗦 – This chain lock of type Helsinki is designed to protect high-quality bikes and motorbikes - no more and no less. Hence, this lock is no lifestyle accessory with exciting gimmicks. We prioritize security by using an especially strong Titanium steel and a particularly safe cylinder that matches car security standards. We combine years of experience in the field of bike security with our high German security standards. For details, please see below.
- 𝗦𝗢𝗟𝗜𝗗 𝗦𝗧𝗘𝗘𝗟 𝗜𝗡𝗦𝗧𝗘𝗔𝗗 𝗢𝗙 𝗟𝗜𝗚𝗛𝗧 𝗦𝗧𝗘𝗘𝗟 – In contrast to many other chain locks who are advertised as lightweight, we do not use light steel with reduced safety. We believe there is simply no shortcut for security. That is why our lock is made of solid hardened steel and, thus, is especially secure against bolt cutters & metal saws. The price of this high anti-theft focus is a heavy lock weight of 5.5 lbs. Greatly suited for motorcycle scooter moped ebike pedelec electric bike & bike trailer.
- 𝗘𝗫𝗧𝗥𝗔-𝗟𝗢𝗡𝗚 𝗟𝗢𝗖𝗞 – The longer the lock, the more convenient and secure the bicycle can be locked. This bike chain lock has a spacious total length of 4 feet / 49 inch / 125 cm. This length is important to securely lock both your bike frame AND the front wheel to a fixed object. Or to secure several bikes at once.
- 𝗛𝗜𝗚𝗛 𝗦𝗘𝗖𝗨𝗥𝗜𝗧𝗬 𝗖𝗛𝗔𝗜𝗡 – The lock chain provides a high level of security against bolt cutters & hacksaws due to the 0.33" / 8.3 mm strong 4-edge links. Additionally, the lockhead offers an anti-lock-picking cylinder. To also protect your bike’s varnish, the chain is coated with a soft & robust sleeve. The lock comes with 4 keys.
- 𝗕𝗘𝗧𝗧𝗘𝗥 𝗠𝗔𝗦𝗦𝗜𝗩𝗘 𝗧𝗛𝗔𝗡 𝗦𝗢𝗥𝗥𝗬 – The very long & massive lock offers a convenient balance between security and weight. On the one hand, locks with chain diameter of 0.25" or less are much lighter, but hardly offer a reliable protection. On the other hand, this chain lock is highly secure, but please consider the rather high weight of 5.5 lbs, and only buy this lock if the weight is acceptable for you. Please keep in mind, as we like to say: Better massive than sorry.

## Questions & Answers

**Q: Is it resistant to rain?**
A: Dear bicycle enthusiast, this lock is designed to be resistant to rain as well as heat and frost. And if there should ever be a problem, please contact us and we will find a good solution for you. Best regards, your team from Stahlwart

**Q: Level of security? In numbers please. Is it 10 of 10 like your U-lock?**
A: The Kolburg Chain lock is quite the high quality chain lock I expected.  I like to say the level of security is high but feel it’s better and more versatile than a U-lock.  Heavy and quite the deterrent.  So far a 10, but it will take a thief to know the truth.  Recommend this lock.

### ⭐⭐⭐⭐⭐ best and fastest security for your buck
*by R***. on April 12, 2026*

Great for securing your bike with a well made key and lock which is easy to operate and lock speedily. The chain inside a nylon sleeve hasnt failed me yet. and surely will deter most who would try to gank your ride. :)
