Test result preview
The Dunlop bike lock offers a high level of security for bicycles, e-bikes and scooters. With a security level of 8 and a length of 100 cm, this lock is ideal for protecting your bike against theft. The chain is made of hardened steel with 6 mm thick links, making it very difficult for thieves to cut through the lock.
A special feature of this lock is the 5-digit numerical code, which allows 100,000 different combinations. Compared to conventional 4-digit locks, this offers significantly higher security. The numbers are easy to set and are also easy for children to use.
The chain is covered with a special fabric tape that is UV-resistant and protects your bike from scratches. The coating also ensures that your hands remain clean when using the lock.
The lock is not only robust and secure, but also practical to use. It can be easily wrapped around the seat post with three turns without interfering with pedalling. With a weight of 840 grams, it is light enough to be easily transported.
All in all, the Dunlop bike lock offers an excellent combination of security, ease of use and protection for your bike. It is a reliable choice for anyone who wants to effectively protect their bike against theft.

The first impression of the Dunlop bike lock is predominantly positive, particularly with regard to the packaging and contents. The lock is packed securely and compactly, which gives a feeling of quality and reliability as soon as you unpack it.
The packaging itself is robust and attractive and contains clear information about the security features and handling of the lock. The packaging is not excessively large, which makes it more environmentally friendly.
When you open the packaging, you will find the lock well protected and in perfect condition. The numerical code is already preset and easy-to-understand but too small printed instructions for changing the code are included.
The high-quality workmanship and the solid weight of the lock leave a good impression and convey security and durability.
Overall, the first impressions of the packaging and contents are very satisfactory and strengthen confidence in the product and the Dunlop brand.

The Dunlop bike lock is particularly impressive in terms of its workmanship and appearance. The chain is made of hardened steel, which gives it a solid and trustworthy feel. The links are evenly and cleanly processed, which indicates a high manufacturing quality.
The lock itself is perceived as stable and durable. The numerical code mechanism works smoothly and is easy to set. The numbers are easy to read and the mechanism engages precisely.
Visually, the lock impresses with its simple but elegant design in black. The chain coating is not only functional to prevent scratches on the bike, but also gives the lock an attractive appearance. The black colour goes well with most bikes and e-bikes and makes the lock inconspicuous and stylish.
To summarise, we are very pleased with the finish and appearance of the Dunlop bike lock. It makes a high-quality impression both visually and haptically and fulfils the expectations of a secure and durable bike lock.

On the Amazon platform, consumers rate the product with an average of 4.5 stars. In individual cases, there is criticism that the combination lock can stop working properly after a short time. On the other hand, the price of the chain, the good length and the easy handling of the combination lock are positively emphasised. In our practical test, we were able to confirm that the solid quality and functional combination lock of the product is well received by customers. Based on the tests, we cannot confirm the criticism levelled by consumers at the combination lock of the bike lock.
Prices of up to €89.20 are charged on the Internet for equivalent products. Very cheap products are available from as little as €7.99 . The Dunlop bike lock is therefore currently in the lower price segment with a price of €19.99. For the quality and performance received, the price-performance ratio is very good.
