Dear Olaf, Jurgen, Martin (etc. in random order), first let me explain that it never was my intention to decrease the value of the python-design in favor off the Flevo. I like both designs. As earlier told i like to combine the positive aspects from different designs (f.i.using a diabolo rubber on the python; it helps a lot in keeping a straight line when riding and increases the self-centering aspect). Now, for the "FleThon", as you called it, i mentioned this model as an example of a different Flevotype, maybe an evoluated one. I also give my thanks to Jan Brandse, he is the originale designer off this model! And, yes i would love to give some comment about riding the Flevo, Python and the FleThon, but in riding the last one i just do yet have way to little experience (the bike is just finished), i just need more excercise and feel-good-and-save-riding moments. As also earlier mentioned it switching form one bike to another takes a certain amount of time before you feel comfortable again on that bike. So, be patience and soon i will give my view in riding experience caused by a positive respectively a negative trail on a low centre steered bike! I just hope the wheather will improve a lot, it is just raining pigs and sheeps (.those are my patts, instead off the usual, conventional cats and dogs). Greetings and regards, henk.
