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.

The surface of the Kilimaharo tube issmooth and even when first rolled out. No visible production defects or material irregularities are apparent. The valve is firmly in place and straight, indicating precise workmanship. The vulcanisation seam is also cleanly executed and barely noticeable. The material thickness appears well thought out: not too thick to add unnecessary weight, but sturdy enough for everyday use. BikePeak has opted for a classic deep black colour. Overall, the tube gives a high-quality impression that can compete with well-known brands. Those who pay attention to details will not be disappointed.
