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.

A small instruction leaflet with installation instructions is also included. Overall, the packaging gives a solid and trustworthy impression that makes you want to try it out in practice.

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.
