<p>A tricycle (810) may be operable between a first mode of operation steerable by a tricycle rider, and a second mode of operation steerable by an individual pushing the tricycle. In both such first and second modes, the frame (700) of the tricycle (810) is configured to rotatably support the rear wheels (400) and configured to support the head tube (707) at a distance from the rear wheels (400) such that a distance between the head tube (707) and rear wheels (400) need not necessarily be changed even when the front wheel axis location is changed from one mode to another.</p> |
