Tyson not 100 percent, Bolt training this season and Asafa answers a questions : Speakers & Interviews

A bike actually would work against you on starting speed, depending on how its made. Again trust, Bolt is beatable even at his best, but it definitely doesn't look that way and who knows when his record will be broken. He may actually lose a race long before his record is broken though.

BOLT IS THE FASTEST IN THE GLOBE AND CANNOT LOSE THE 100M ONCE HE IS RUNNING, UNLLESS THE OTHER REST OF RUNNERS IS GOING TO RIDE A BIKE OR HORSE.
