An elliptical exerciser includes two swing arms pivotably connected to a mediate portion of a post on the base and two slidable link units are pivotably connected to two respective lower ends of the two swing arms. Each slidable link unit has a first link and a second link wherein two connection parts respectively extend from two ends of the first link at an angle. The first end of the first link is pivotably connected to the wheel. Two ends of the second link are pivotably connected to the two connection parts by two connection members which allow the second links to be pivotable relative to the two connection parts. The two second links have two pedals connected thereto so that the pedals can travel a further distance relative to the first links so as to increase the distance of the ling axis of the oval trace.
