The kicksled or spark is a small sled consisting of a chair mounted on a pair of flexible metal runners that extend backward to about twice the chair's length. The sled is propelled by kicking (sparka or sparke 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. Estonian calls it either a 'pushsled' (tõukekelk) or 'Finnish sled' (Soome kelk). Some other possible translations are kicker and chair-sled.
