Stationary bikes, a fitness training equipment (indoor bike where goal is aerobic training not movement over distances) originate in late eighteen century when Francis Lowndes developed Gymnasticon machine. Machine was very similar to modern stationary bikes and it was promoted as a machine for complete body workout, but Francis imagined machine as machine for joint exercise. The Gymnasticon had a set of flywheels that connected the wooden treadles for the feet to cranks for the hands, which could drive each other or operate independently.
