Two pedals, one leg - the bicycle and Emmanuel Ofosu Yeboah weren't exactly made for each other. He got on one anyway, and it changed his life. Changed other people's lives, too. Now the San Diegan wants to do it all again. Yeboah, 38, was born in Ghana without a shinbone in his right leg. The deformity set him up for life as an outcast. His mother believed he could be more than that. Her dream became his dream. After she died, he decided to honor her hopes for him by cycling one-legged across Ghana. He wanted to raise awareness for the plight of the disabled while setting an example for what was possible. He rode a mountain bike almost 400 miles in 10 days, clad in a T-shirt with The Pozo" - disabled person - printed on the front. "Pozo! Pozo!" people yelled as he rode by, but they weren't making fun of him. They were cheering. By the time he was done, he'd gone from curiosity to national hero. Government officials, their eyes opened, eventually passed legislation giving the disabled greater rights. In 2005, he was the subject of a documentary, "Emmanuel's Gift," narrated by Oprah Winfrey. And then the public's attention moved on, as it always does, to other dreams, to other dreamers. Except Yeboah isn't finished with his. He wants to build a school in Ghana for the disabled. So he's formed a nonprofit organization, Emmanuel's Dream. But he also knows what got him noticed in the first place. He's getting back on the bike. The plan is to ride from San Diego to Oregon, 1,082 miles in 21 days.
