The Dandy Horse, also known as the hobby horse, is an early type of bicycle invented in the early 19th century. It was created by German inventor Karl Drais in 1817. The Dandy Horse had two wheels and a wooden frame, but it did not have pedals. Riders propelled themselves by pushing their feet against the ground, similar to walking or running. This invention marked a significant step in the development of personal transportation. The Dandy Horse influenced later designs, leading to the creation of the modern bicycle. Its simplicity and ease of use made it popular among early cyclists, paving the way for advancements in cycling technology.
