Zolder has also been used for cycling events including the UCI Road World Championships twice in 1969 and 2002 and the UCI Cyclo-cross World Championships in 1970, 2002 and 2016. The latter saw the first confirmed use of mechanical doping when Femke Van den Driessche was found to have a secret motor inside her bike. Since 2009, Circuit Zolder has hosted a cyclo-cross race in December for the World Cup. The circuit hosted the UCI BMX World Championships in 2015. In 2019 and for the first time ever the UCI BMX World Championships will return to Circuit Zolder.
