Recovering addict, Robin McGeough rode the unique bike each year to raise money for drug and alcohol treatment for his charity event, Run 4 Recovery.
But weeks before this years event, someone stole the bike from his garage in Pasadena, McGeough said.
The elliptical bicycle was specially designed to allow McGeough to complete the grueling 500 mile journey from San Francisco to Pasadena over a 10 day period.
McGeough hoped the thief would have a change of heart and return it.
