Abstract: A person rides the Tri-Axial Control Device standing on pedal assemblies. The pedal assemblies are attached to a control axial member thus forming the Tri-Axial Control Device. The control axial member on the vertical stick, can rotate fore and aft, and turns the front skis and/or wheels. Changing the angle of the vertical stick side-to-side changes the pedal angle. If the rider falls forward the front stick can rotate away. Various torsion controls rod assemblies and pedal assemblies can be utilized to create a unique tri axial device. The device can be folded, is lightweight and can be manufactured without welding. No special equipment or training is required to operate the device. In addition to its entertainment uses, the mounting device for portable electronics can also be used for added safety by adding a global positioning system or other electronic signal device, allowing safety personnel to locate the rider.
