1894 Hildebrand & Wolfmuller
Germany's Hildebrand & Wolfmüller was the world’s first mass-produced motorcycle. The Hildebrand brothers, who were steam engineers, partnered with inventor Alois Wolfmüller to design the gasoline-powered, twin-cylinder, four-stroke, 2.5-hp engine. Around 2000 units were produced and sold. Most likely, the customers had never even seen such a vehicle in their lives!
