Wesley Williams auditioned in Season 10 as one half of the duo The One Wheel Wonders. He auditioned for the 14th series of Britain's Got Talent, where he made it to the live shows but was eliminated in the 5th semifinal. In February 2020 he received the Guinness World Record for 'The World's Tallest Rideable Unicycle' by riding a Unicycle that was 29 Feet and an Inch long in Girona, Spain.
Wesley Williams' audition in Episode 1506 consisted of doing various tricks while riding a unicycle. Heidi Klum was not present, but Howie Mandel, Sofia Vergara, and Simon Cowell voted "Yes", sending him to the next round.
Wesley Williams was shown at the deliberation. Although his verdict was never shown, he did not make the Quarterfinals, eliminating him from the competition.
After The Show
Wesley Williams competed on the Italian competition series Tu si que vales in 2020 in which he was a finalist. In 2021, he auditioned for the 7th season of Spain's Got Talent, where he received the Golden Buzzer from judge Dani Martinez on the season premiere, yet was forced to withdraw after sustaining an injury whilst practising his performance by falling off of his unicycle from 27 feet in the air, with the severity of his injury preventing him from performing for at least a further six months. However, Williams was informed that he could return to perform in the Semi-Finals of the eighth season of Got Talent Espana instead.
The same year he also auditioned for Germany's Got Talent  and France's Got Talent , and initially reached the Semi-Finals of both shows before having to withdraw, due to the same injury which caused him to withdraw from Got Talent Espana. 
Wesley Willams was the replacement act for Divas & Drummers of Compton in case they were not able to perform due to one of the members catching COVID-19 but the member recovered and the group performed nonetheless. It is known that his quarterfinal performance was similar to what he did in the semifinals of BGT Season 14.
