Which motorcycle is generally credited as the world’s first series-production motorcycle, built in Germany in 1894?

The Hildebrand & Wolfmüller is generally credited as the world’s first series-production motorcycle, built in Germany in 1894.

Heinrich and Wilhelm Hildebrand developed the machine with Alois Wolfmüller and mechanic Hans Geisenhof. Its 1,489 cc parallel-twin engine used atmospheric intake valves and a distinctive connecting-rod arrangement derived from steam-engine practice. Production took place in Munich, and the model was also marketed in France under the name Pétrolette.

The earlier Daimler Reitwagen of 1885 is often called the first motorcycle, but it was an experimental vehicle rather than a series-production model. That distinction is why the Hildebrand & Wolfmüller usually receives the production-first title.

The motorcycle was not a commercial success. Its direct-drive layout, lack of a conventional clutch, and difficult starting procedure limited usability, while the company soon encountered financial problems. Nevertheless, it established the basic idea of a purpose-built, commercially manufactured motorized two-wheeler.
