Abstract

A magnetic control water resistance rowing machine has a main rack, a ribbon, a ribbon recycling plate set, an aluminum wheel water resistance device set, a magnetic plate set and a seat cushion. The ribbon is connected with a ribbon recycling plate. The ribbon recycling plate set is mounted on the main rack by a torsion spring to recycle the ribbon when the ribbon is loosened; the aluminum wheel water resistance device set is mounted on the main rack and the aluminum wheel water resistance device set cooperates with the ribbon recycling plate set. The ribbon recycling plate set is connected to the aluminum wheel water resistance set drive; the magnetic plate is mounted on the main rack. The magnetic plate cooperates with the aluminum wheel water resistance. The main rack has a slide rail engagement and the seat cushion is slidably engaged with the slide rail engagement.
