Abstract
A frame supports two rear wheels, a front wheel and a seat. Extending upwardly from the steering column mounting bracket in the front of the frame is a rocking drive steering column pivotally connected to the steering column mounting bracket. Pivoting the rocking drive steering column back and forth drives a center rocking bar to provide rotation to an orbital ratchet through the orbital ratchet drive rod. The orbital ratchet drives a chain which extends through a drive train to power the rear wheels. The handlebars are connected to a gooseneck extending through the rocking drive steering column. The gooseneck rotates within the rocking drive steering column when the handlebars are turned and provide rotational motion to the front wheel fork shaft through a universal joint to steer the front wheel.
