Well Jo, it's like this.... I like the one with the normal saddle, how long is the seat post?Easy either way, either separately or together.
I'd need 30" from b/b centre to top of saddle, with a good amount in the frame.Seat posts are long, bike is pretty tall anyway with 22" Tyres.
One of the tallest racesThe Dutch must be very tall as the seat post is 18" long.
There was a nice Bike Friday on marktplaats.nl
