Historians have mainly reached a consensus that the invention of the bicycle belongs to German Baron Karl von Dreis who June 12, 1817, drove his two-wheel invention in the city of Mannheim in southwest Germany.

The vehicle, which the Germans called "drezina" after its inventor, had a wooden frame, two wheels and had no pedals. Baron patented it in 1818, but was no commercial success.

On this occasion, Mannheim has a variety of events, including a stunt show of Belgian cyclist, and the culmination of event is a race of folding bikes around the city water tower with more than 200 people participating.
