Students also got a glimpse of why Wilhelm is dubbed "the world's fastest spinner on a BMX bike". He showed off some of his popular tricks, while sharing his personal story of triumph.
Wilhelm has been a motivational speaker for 10 years, telling youth across the country how to deal with bullies without getting into fights.
"I think it's good to start young and teach them young," said Wilhem. "Growing up in first grade, I never heard this word. And then one day I heard it: bully. And I was like what is that? I just thought the kid was being mean to me. But he was a bully, and that was the first time I was introduced to that word."
Wilhelm said he came in last in his first BMX race, but he says he didn't let that discourage him. He continued racing, eventually winning three medals and two national titles.
