The E-MX Race of Champions is the world's most important race for electric motocross bikes. Since its inception in 2012, as a part of Circuit Zolder's Clean week, the race has been staged annually. In its current form Stefan Everts was the first E-MX champion in 2013. He was followed in 2014 by Swiss motocross star Valentin Guillod. Last year Pauls Jonass was crowned E-MX champion.
