A 1905 Leo Two-Cycle motorcycle, believed to be the only remaining model manufactured by the L.A.-based Mitchell Motor Company of Oakland, California, has recently been discovered in the warehouse of a New England museum. The motorcycle is now being sold on January 10th by Bonhams at Bally's Hotel & Casino in Las Vegas. The Leo company seems to have only been in the business of manufacturing motorcycles for one year in 1905, the reason for it's closure remaining a mystery to anyone who is familiar with the company. Due to it's rarity, the motorcycle carries a pre-sale estimate of $25,000 to $35,000.
