Phaeton Moto-cycle

Lucius Copeland built a steam powered high wheel bicycle in 1894 and introduced it at the Arizona Territorial Fair that year. This gave him the confidence to continue his work and the Phaeton Moto-Cycle was introduced in 1886. He produced about 200 of these machines in the next five years before deciding he wasn't making enough money and retired.

 At least that's the story at Wikipedia, he is not mentioned in the ad above, and apparently lived on the other side of the country, so there's a gap here somewhere...
