A must-have for do-it-yourselfers! Remove the Scorpion's seat and clamp the Workstand Bracket in its place.Ā You can now clamp the trike right into a standard workstand, allowing you to work on your Scorpion with convenience and ease.Ā Also works with HP Velotechnik's two-wheel recumbents like the Street Machine, Speedmachine and Grashopper (all models except the Spirit).
