ABSTRACT:
A two wheel steering bicycle with two steering controls and rider positioned facing forward. A top tube member connects the rear head tube to the front head tube. The rear wheel attaches to the rear fork extending upwards. The rear fork steerer column passes through the rear head tube and can rotate within the rear head tube by means of a bicycle bearing headset. A rear steering handle is connected to the rear fork steerer column. The rear steering handle is designed to contact the rider's first hand. The front wheel attaches to the front fork extending upwards. The front fork steerer column passes through the front head tube and can rotate within the front head tube by means of a bicycle bearing headset. A front steering handle is connected to the front fork steerer column. The front steering handle is designed to contact the rider's second hand. A seat tube member attaches to the top tube member. A bicycle saddle is attached to the seat tube member in such a way as to position the rider facing forward parallel to the longitudinal axis of the top tube member. A bicycle bottom bracket, front sprocket, left and right crank and pedals are attached to the device. The rider's left hand is positioned at the rider's left side and contacts one of the steering handles. The rider's right hand is positioned at the rider's right side and contacts the other steering handle. The saddle and steering handles should be adjusted so that the rider's body is roughly balanced across the vertical plane of the rear and front wheels. The device moves forward and the rider keeps the device balanced by constantly correcting the front and rear steering handles. It may take some practice to make this correction reflex, but once mastered this device offers more control and artistic expression than a currently available bicycle.
