Abstract
A two-wheeled vehicle similar to a bicycle has a frame comprising four pivotably interconnected frame members of which the lower one is provided with a bearing for a sprocket wheel of a chain drive. A crank arm is connected to the sprocket wheel and cooperates with a connecting rod pivotably connected to the upper frame member carrying a saddle. Pedals are mounted on the lower frame member or the front frame member, the latter guiding the steering handle and the front wheel fork. The driving torque is achieved by alternatively shifting the weight between the saddle and the pedals. The saddle moves up and down reciprocally to the pedals and the steering handle forth and back giving the illusion of riding on horseback. The same structural principle is suitable also for a home-trainer.
