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.

BikePeak
Zugtaps bicycle inner tube

Product description provided by the manufacturer

BikePeak’s Zugtaps is aimed specifically at young cyclists and parents who value safety and reliability. The tube is suitable for20-inch children’s bikes with tyre widths from 40 to 62 mm (ETRTO 40–60-406). It is made from elastic butyl rubber, which is known for its high airtightness and durability. A 40 mm Schrader valve (car valve) makes it easy to inflate – even at petrol stations. The model is compatible with popular tyre brands such as Schwalbe, Continental and Kenda. The strength of the material, which rarely needs to be re-inflated, is particularly evident in everyday use. BikePeak offers the inner tube in a practical pack of two, which is ideal for families with several bikes. The mobility guarantee rounds off the customer-friendly offer.

  • High reliability
  • Universal compatibility
  • Low air loss
  • Robust workmanship
  • Relatively heavy
  • Less efficient rolling resistance

When first unrolled, the surface of the tube appears smooth and even. There are no visible manufacturing defects or material irregularities. The valve is firmly in place and straight, which indicates precise workmanship. The vulcanisation seam is also cleanly executed and barely noticeable. The material thickness appears appropriate: it is not too thick to add unnecessary weight, but sturdy enough for everyday use. BikePeak has opted for a classic deep black colour, which blends in discreetly with any children’s bike. Overall, the inner tube gives a high-quality impression that is comparable to that of well-known brands. On closer inspection, it becomes clear that the quality of the workmanship is impressive.
