Hi all, Good to see a list of variables being born for the python project. just built my no welding NON python, http://www.nupi.nl/index.php?id=383d7200f0 a bit reluctant of welding, and this one is to discover the whole recumbant thing. in following of the python bike i called this one camel bike :-), as its like riding between the humps of a camel with this thing my next will be python though. ok get to the point. but what is relevant to the python forum is my findings about tirepressure first i wrote an email to Jürgen about the idea of front suspension. this was also with the idea in mind that front suspension could damp the dynamic loads on the center steering pivot. he replied that this was not needed. now i see his point after constructing and riding my own bike what i found out with my bicycle is that by lowering the front tire pressure you will get a conciderable more comfy ride also seems not to bounce so much when you lower pressure, and more stable therefor. //Dirk Jan Luiting
