ABSTRACT OF THE DISCLOSURE A pedal drive for a tricycle having a single driven rear wheel and two steerable front wheels is described. There are a pair of matched, laterally spaced sprockets mounted on a transverse shaft and a pair of matched, laterally sprockets rotatably mounted forwardly of the sprockets on said shaft. Each of the forward sprockets is aligned in a common plane with a corresponding sprocket on the transverse shaft. An endless chain extends about each pair of corresponding sprockets. Two elongate arm members, each with a foot pedal mounted on its bottom end, are pivotally mounted on a frame member of the tricycle. Two connecting links join the arm members to the endless chains. A third endless chain transmits power via a third sprocket on the transverse shaft to the rear wheel. The preferred tricycle is tiltable in order that it can maneuver corners quickly. Spring means are provided to bias the tricycle towards a desired tilting or non-tilting position.
