It was not a radiator that first made Zehnder a household name, but a motorcycle. In the 1920s, the Zehnder light motorcycle was a popular and affordable form of mobility for ordinary people. Although the Zehnder family first went into business in 1895, it was not until 1930 that they invented the product that would lay the foundations for the company’s future success: Europe’s first steel tube radiator. Over the years, a small mechanical workshop became a group of companies with 3000 employees.
