Who invented bicycle in 1818?:
The invention of the bicycle is often attributed to Karl von Drais, a German baron who invented a two-wheeled, human-powered vehicle in 1817. This vehicle was known as the “running machine” or “dandy horse” and was propelled by the rider pushing their feet against the ground. While it is often considered a precursor to the modern bicycle, it lacked pedals and chains and required the rider to use their feet to move it forward. The addition of pedals and chains was later introduced by Frenchman Pierre Lallement in the 1860s, leading to the development of the first true bicycle.
