## Overview

The KOHLBURG Security Chain Lock Helsinki model is a 125cm long, 2.5kg heavy-duty bike lock made from specially hardened titanium steel with 0.33" thick 4-edge links. Certified Sold Secure Gold, it offers top-tier protection against bolt cutters and lock picking. Its extra length and protective sleeve provide versatile, scratch-free security for high-value bikes, e-bikes, and motorbikes, making it the go-to choice for professionals who refuse to compromise on safety.

## Description

Durable 4ft/120cm titanium steel chain lock for maximum security. Designed to protect high-value bikes and motorbikes, prioritizing safety over lightweight.

Review: Exactly what I’ve been looking for - I recently purchased this chain lock with Sold Secure Gold certification, and I couldn’t be happier with my choice. At 120 cm long, it’s the perfect length to lock both the bike frame and rear wheel securely to a bike rack or railing. This gives me peace of mind, especially when leaving my bike in high-risk areas. Yes, it’s a bit over 2 kg, so it’s on the heavier side, but that’s a small trade-off for the serious protection it offers. The weight actually feels reassuring—it’s clear this lock is built to withstand serious attempts at theft. The chain links and lock mechanism exude quality, and you can tell a lot of thought went into its design. 5-star recommendation from my side.
Review: Long - Great for our mountain bikes. Long enough to easily lock two bikes to a lamp post or tree. Strong enough to deter even the most determined, bolt-cropper wielding thief. Cloth covering protects bike from scratches. My ten year old thinks it's a bit heavy. I tend to carry it across my body like a handbag when I use it.

## 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 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 / 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.
