  • Patent number: 6811172
    Abstract: A vehicle such as a bicycle or tricycle having a front steering assembly and a remote, rear steering assembly. The front steering assembly has a steering sleeve with a rotatable front shaft within the sleeve that is connected to the front wheel. The rear steering assembly has a rear shaft rotatably mounted in a steering sleeve and both of the shafts has a steering device such as handlebars accessible to users. The shafts are coupled together to rotate in tandem by means of a substantially flexible coupling, such as a chain operatively connected between sprockets mounted to each of the shafts. Turning either of the handlebars thus turns the front wheel to steer the vehicle.
