An occupant-propelled vehicle comprising a vehicle frame, a vehicle propulsion system with a movable force receiver, and a vehicle steering arrangement in one embodiment comprising a tilt-grip steering post, a steering drum, a steered wheel, a steered drum, and a flexible, sheathed cable. An inner member of the cable overlies the steered drum and the steering drum whereby a pivoting of the tilt-grip steering post induces a steering of the steered wheel. The steering post may have an axis of rotation perpendicular to its longitudinal axis and tangent to an arc of rotation of the moveable force receiver. The diameters of the steered and steering drums may be varied, and the steered drum may be disengagably indexed to the steered wheel. The steered wheel may be coupled to a second wheel to steer the second wheel in response to a steering of the steered wheel. In a second embodiment, the steering arrangement may comprise a flexible, sheathed cable with an inner member for transmitting loads in tension and compression that is reciprocatably retained within an outer sheath. A first end of the inner member may be coupled at a pivot point to the steering post and a second end of the inner member may be coupled at a pivot point to the steered wheel such that a pivoting of the steering post yields a steering of the steered wheel. The pivot points of the steering post and the steered wheel may be varied to mechanical advantage.
