I almost picked up one of those for a project bike, back when Dick's was closing them out for <$99. That seat put me off, though. The bike itself would be OK for what it is, except for the seat. I suppose a seat could be fabricated, along with a method to mount it. I think what would work best would be a Bike-E type seat with a padded plywood base and a mesh back that reached maybe to the rider's shoulder blades. It would be very easy to spend more than the cost of the bike just to put a decent seat on it. I wonder if AD Carson over at recycledrecumbents would be willing to make something? He's been known to fabricate a solution or two.
