Derny was the name of a specific company that manufactured Entraineurs (used to pace bicycles in certain road races and on the track) and for training. They also made other machines for touring and a tandem for touring as well as something that was close to being a moped. Modern Dernys are still being made in Europe with I think mostly Steyr Puch motors. The rules governing the design and construction of these machines have not changed significantly over the years and do not allow for any variation in design. They do not have rollers. Only the full size pacing motorbikes have rollers. Many tracks do have have adapted motorcycles for training and many have rollers but these are not Dernys in any sense of the word.

Please some pictures I posted at:

These pictures apart from the model are from the Boneshaker article on Dernys.
