An event in which a bicycle drafts behind a motor vehicle, usually a motorcycle. This was the most popular form of track racing in the 1920s and '30s. Special motorcycles called "Dernys" are used for track events. The motorcycle driver sits very erect and far back to improve the drafting effect. There is a horizontal roller mounted behind the rear wheel, so that, if the bicycle gets too close, the bicycle's front wheel will hit the roller, rather than a rigid part of the motorcycle.
Some road racers train behind a motorcycle, which allows the coach to accompany the rider, and teaches the cyclist to be comfortable controlling the bicycle at higher-than-average speeds.
