Abstract
A mechanism for manually powering a vehicle is provided. The mechanism includes a frame and a first driver attached to the frame. The first driver rotates a driven wheel. A lever arm is pivotally attached to the frame and includes a first end having a pair of handles sized to be grasped and moved in a rowing motion by both hands of a person and a second end that rotatably attaches to a disk shaped second driver. A linkage is moved by the second driver when the person pivots the first end of the lever arm and the linkage rotates the first driver and the driven wheel. A steerable wheel and a steering member that are operated by the lever arm steer the steerable wheel. The steering member communicates moveably with a telescoping universal joint, the telescoping universal joint enabling the lever arm to be pivoted and steered.
