Two identical wheels, a wooden frame, a basic handlebar, a steering device on the front wheel, a seat and... that’s it! In all, the incredible machine weighed 17 kg and was propelled forward using both feet. 
The "Laufmaschine”, or “running machine”, was invented by German Baron Karl Drais von Sauerbronn, who filed its French patent in 1818, one year after its launch in Germany. Sold under the name “velocipede”, the first bicycle in history would see many modifications over the following two centuries: pedals, derailleur gears, greater speed, a lighter frame and even the addition of a motor.
Yet today it’s still in the race as an option for riders of all ages!
