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.

Robust security meets practical design – the HIPARK folding lock offers a solid solution for everyday bicycle protection. Made of hardened steel, it resists common break-in methods such as bolt cutters or lever tools.

A holder for attaching it to the bicycle frame is included, making it easy to carry around. Thanks to the key locking mechanism, there is no need for a combination code, which simplifies operation. The lock is suitable for urban use as well as for longer tours.

Overall, the product presents itself as a well-thought-out combination of security, convenience, and mobility.
