Pythonauts.....has anyone ever ridden a python or Flevo with the pivot in front of the hip joint...ie level with the front of the seat? I would be interested in how much PSI was noticed. Thanks for the news about Dennis Renners Trike Rhisiart, ....a very neat arrangement and seems to ride very well. I wonder how similar this is to the PX5 and whether you would feel like you are about to be thrown out of the seat when turning. The question remains open as to why there was PSI noticed on Jurgens PX5. I can't understand how there could be any with the pivot BEHIND the hips??...any comments Jurgen? Dirk? Cheers to you all Howard
