Cross-country cyclists ended a 650-mile trek in Las Vegas Thursday to draw attention to a disease most of us know nothing about. It can leave a person disabled at a very young age.

Among the cyclists, a young man named Kyle Bryant, who isn't letting Friedreich's ataxia slow him down. Bryant led the way, as 21 cyclists pedaled up to the Flamingo, ending a ride that began in Sacramento two weeks ago.

Although Bryant's legs have limited movement, a specially designed bike allows him to go great distances -- with the purpose of getting the word out about ataxia.

"It directly affects me and my whole family. And we feel very strongly that this disease deserves attention, and it effects a lot of really great people that we've met over the years," said Bryant.

Bryant was diagnosed with Friedreich's ataxia about 10 years ago. The debilitating disease often occurs between the ages of 5 and 15. It affects muscle coordination and sometimes leads to heart failure in its young victims.
