What I found difficult in former times: when switching from

practice to feel safe when riding. That was so annoying, that
I finally abandoned the airbike.
Last weekend Peter from Efringen-Kirchen visited me. After 15 minutes he
could ride very good on my python. He has several years of airbike-practise.
Marc,
your python is also different. So there is may be some pattern we can
see here. I just copy from a former mail:
marc: wheelbase: 1280mm
dirk: 1080mm
standard: 1300mm
marc: steering angle: 65°
dirk: 60˚
standard: 70˚
marc: trail: -280mm
dirk: -140mm
standard: 300mm
marc seat height: ~200mm
dirk: 280mm
standard: 300mm
I cannot see the pattern ;-(
Sigh, it is difficult to be objective here. There are three different
people testing three different cycles. This does not work. May be I am
just imagine things, and on Torbens bicycle --thats the one I tested--
the pedals where very far away. So may be just that was the problem.
I tried to ride on his airbike already last summer but without success. but
now after 5 minutes I felt quiet safe on the airbike, safer than on the
python. perhaps it's because of the steering-damper?
Maybe: I have trouble riding on a standard flevo, even though I cycle a
flevo *all the time*. The damper is much to hard for my taste. On my
flevo there is only a quite small damper (ø30, height 40mm). (It feels
even better with no damper).
I want to be able to walk with the cycle, so I am considering to mount a
damper on the python, or find some other solution.
I tried pushing on the seat like Jürgen once mentioned on this list, but
I can't push hard enough. And I begin to feel my back hurting from
steeping over, carrying the bike, or simply holding it (I do have a back
problem, so it is an important problem for me).
The ideal would be something (a spring) that is on-off able. Something
that can be done by "the press of a button". So when I stop I flip a
"switch", and it is in "springy"-mode, and when I start cycling again, I
put it in "self centered"-mode. I should also be easy to implement.
