An exercise vehicle is provided with an improved push/pull cable steering system for use in directing vehicle travel without interfering significantly with vehicle power. The vehicle includes a frame with a drive system attached thereto and includes at least one drive wheel coupled with the frame. Preferably, the drive system includes arm levers operatively connected to the drive wheel so that counter-reciprocal movement of the arm levers produces rotation of the drive wheel. The steering system includes a guidance wheel rotatably coupled with the frame, an elongate steering crank which is operatively coupled with the guidance wheel, hand levers pivotally attached to the arm levers and push/pull cabling assemblies connecting the hand levers to the steering crank. When one hand lever pivots, the steering crank rotates, causing the other hand lever to pivot in the same direction of rotation while the freely rotatable ends of the hand levers move in opposite translational directions, and causing the guidance wheel to turn.
