About Us

Prüfengel offers authentic consumer tests in which real users share their experiences with products. Our tests are based on practical applications in everyday life and reflect the opinions of consumers. As we focus on consumer tests, we do not carry out any material, long-term or laboratory tests. The tests are carried out by 1-2 independent consumers over a period of 7-14 days. The exact test conditions can be viewed in the test plan of the respective test report – click here to go directly to the test plan.

Manufacturers provide the tested products free of charge. We charge a one-off test fee for carrying out the tests. In addition, manufacturers pay an annual licence fee for the use of the Prüfengel seal. We also receive a commission for linking to manufacturers’ websites. These remunerations have no influence on our test results or ratings.

We guarantee transparency and a fair evaluation. For a detailed insight into our comprehensive evaluation process, please click here.

AARON
Bolt handcuff lock

The Bolt handcuff lock from the Aaron brand is a high-quality and sturdy safety lock for e-scooters. The product is versatile and can also be used to secure scooters, bicycles or baby carriages, for example, depending on requirements. The quality and workmanship of the lock should be emphasized positively. The 15 mm thick steel chain inside is resistant to cutting, hammering, sawing and drilling and therefore offers theft protection. Only durable materials were used in the manufacture of the product – it is made of stainless and hardened steel. To ensure that the e-scooter to be protected does not get scratched, the clamps and chain of the lock are coated with nylon. Three keys are included in the scope of delivery, which work on both sides and therefore make locking very easy. The adjustable size ensures a high degree of flexibility – the diameter of the clamps can be set between 74 and 85 mm as required. The handcuff lock is kept in an unobtrusive black.

  • Particularly theft-proof (cut, hammer and saw resistant, drill-proof)
  • Durable materials
  • Versatile (also suitable for bicycles, baby carriages etc.)
  • Convenient handling
  • somewhat heavy

The first impression

Packaging and contents

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?

When you hold the Aaron Bolt handcuff lock in your hand for the first time, you immediately notice its weight. At 1.5 kg, the lock seems quite heavy at first, but due to the materials used, it can be assumed that the weight of the product can hardly be reduced. Due to its size, the lock is easy to transport and can be taken anywhere if required. The chain of the lock feels very robust and stable and has a coating. The surface of the handcuffs has a rubber-like coating, which indicates that the product can be used safely without leaving scratches on the e-scooter. The three reversible keys supplied also look high-quality and the fact that not just one key but a total of three keys are included with the product is very well thought out. In the event that one of the keys is lost, the two remaining keys are still available to the buyer. The first impression of the handcuff lock is very positive.

We tested the Aaron Bolt handcuff lock on a bicycle . Overall, the handcuff lock offers optimum protection thanks to its resistance to cutting, hammering, sawing and drilling. The high-quality materials are rustproof and therefore weatherproof and made a robust impression in the test. A particularly positive feature is the 23 cm long armored link chain, which can be rotated very flexibly, making it very easy to lock the bike. A nylon fabric is attached over the chain to prevent scratches on the bike. The solid, rubber-like coating of the reinforced clamps also helps to protect the surface of the bike. The locking mechanism is very practical – the links can be locked in two stages so that the diameter of the handcuffs can be set to 74 or 85 mm as required. The handcuffs can be opened and closed quickly and easily. Due to its overall length of approx. 56 cm and its flexibility, the lock is very easy to transport. The weight of 1.5 kg seems quite heavy at first, but does not have a negative effect on transportation. Overall, this is a high quality product and it can be assumed that the handcuff lock is durable. The design, which allows it to be used in a variety of ways on e-scooters, bicycles, baby carriages or even scooters, should also be emphasized positively.
