All Lemon
Bike lock

The All Lemon bike lock is a reliable method of securing your bike against theft.
The bike lock is equipped with a robust steel chain, which is 90 cm long and 6 mm thick. The solid workmanship guarantees additional security. A weatherproof textile coating not only protects against corrosion, but also prevents damage to the bike’s paintwork.
It also impresses with its unique design, which makes it a stylish accessory. Instead of a key, the lock can be unlocked with an individual numerical code, which is a practical solution and minimises the risk of losing the key.
The All Lemon bike lock offers versatile theft protection and is a reliable choice for everyone, whether on a bike, fence or gate.

Here we take a closer look at packaging. Sustainability is becoming an increasingly important factor. In addition, adequate protection of the product must of course also be guaranteed. Are the contents of the packaging complete and does the manufacturer make it as easy as possible for me to use the product straight away?

Price/performance ratio

and ratings from consumers

Finally, we analyse how the product compares to the competition. Can it keep up with the competition in terms of price and quality? Would we generally recommend buying it? We also look at the consumer reviews and check whether the critical and positive reviews are actually justified.

*Themaximum score is 100 points

On the Amazon platform, consumers rate the product with an average of 4.5 stars. In some cases, the fact that the coating can come loose after years is criticised. On the other hand, the robustness 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 are well received by customers. However, consumer criticism of the bike lock’s casing was not justified.

Prices of up to €89.20 are charged on the Internet for equivalent products. Very affordable products are available from as little as €7.99 . The door stopper from GRAUBERG® is therefore currently in the lower price segment with a price of € 20.99. For the quality and performance received, the price-performance ratio is very good.
