Another name for a kicksled. The kicksled or spark is a small sled consisting of a chair mounted on a pair of flexible metal runners which extend backward to about twice the chair's length. The sled is propelled by kicking (“sparke” or “sparka” in the Scandinavian languages) the ground by foot. There is a handlebar attached to the top of the chair back. “Kicksled” is a direct translation of the Finnish word “potkukelkka”. Some other possible translations are “kicker” and “chair-sled”.
