A variable ratio drive system including a variable diameter sprocket and a sprocket diameter changing mechanism is described herein. The variable diameter sprocket includes sprocket portions so mounted in radial channels of a circular support as to be radially movable therein. The sprocket portions include a pin that may be inserted in apertures of the channels. The diameter changing mechanism includes first and second angled abutting portions configured and sized to first move the sprocket portions laterally, then move them radially before allowing them to be reinserted in a new position to cause the diameter modification.
