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 length of 4 feet / 47 inch / 120 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 bikes 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.

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.

As others have mentioned, this is a hefty lock! It’s heavy and pricey and the locking mechanism doesn’t always turn without some wiggling, jiggling, cajoling, and occasionally threats. I never struggle to unlock it, but the rubber creeps up the chain section and makes getting it locked the very last straw if you happen to be running late. That said, I very much still have the bike for which I use this lock and I have always been able to find places to park it because the lock is so versatile. Bike racks, trees, pipes, sign posts, hub cap spokes, a sleeping camel - this chain can wrap around just about anything if it stays stationary long enough and still have your bike waiting there for you when you get back.

Heavy which is to be expected. Quick to lock and unlock. I feel confident when leaving the bikes for a short lunch or run into a local store. If we are going to be out of sight or longer we use 4 layers of defense. One of these chain locks on each bike, a U shaped lock for each and then cable the two bikes together. The fourth is a loud alarm with the sensitivity dialed back to avoid false alarms. The hope is someone else’s bike looks easier to take or it requires more than tin snips the cut away all the junk.

Great customer service. Updated my rating. I unfortunately received a lock that would not unlock after very little use. We tried every key and possible way to unlock it -- but customer service did reach out almost immediately and offered to replace it. Thank you. We purchased a different brand. It was just a bit scary that if I got to my destination and it wouldn't unlock - how would I get home as well as cut the lock off. I will give the lock chain 5 stars. It was heavy duty and will most likely deter any thief. Good length solid chain when the actual lock worked.

This product is one of the better chain locks out there, and there is a good amount of length so that you can attach it to most things. The only downside is that it is a bit heavy, although that's probably due to the strength and quality of the chain. I've watched videos of people cutting through this and it takes several minutes and also a replacement blade to do so, as the first one would become dull trying to cut through it. Therefore this lock would make it exceedingly difficult for any thief to get through, especially in a public place where there are other people around... Overall this one get's the job done!

great strong lock, not convenient for wrap around but I have a paineer that it fits in nicely

The heavy-duty chain lock is imposing. I can't see how it can be defeated without taking a considerable amount of time and sophisticated equipment. It may be heavy, but it can easily fit in my Topeak bag on the rear of my electric bike. I am very glad I purchased this and highly recommend it.

I had used a cable lock previously but learned how easy they are to cut. This chain is beafier than the cable lock and should be able to slow up a thief. At 5 lbs. I can still carry it in my bag on the rack of my electric bike. Now I use this heavier chain lock along with my cable lock for the front wheel.
