Quality seats should accomodate the rider of the Open Waterbike. Comfort and efficent cranking position are important features.
Standard seats designed for recumbent bicycles are a good choice as long as they are suitable for usage on the water.
«A seat that provides good cupping of the back and bottom is most comfortable. Ideally they should be no more than 1 Kg plus brackets. Precise mounting instructions are also needed.» (Rick Willoughby)
