How popular was the running machine in the 1817?

The running machine, or "dandy horse," invented by Baron Karl von Drais in 1817, gained notable popularity as an early form of bicycle. It allowed riders to propel themselves by pushing their feet against the ground, making it a novel mode of transportation. While it attracted attention in Europe, its popularity was somewhat limited due to its lack of pedals and the need for physical effort. Nonetheless, it laid the groundwork for the development of later bicycles.
