Nobuo's trike - with the small front wheel and large back wheels, the
high seat etc. - does it really make use of the "pendulum" effect? Is it
self-stabilizing? The center of gravitiy must be too high, I believe! It
works, obviously, because he could control it with the handlebars on
that mad downhill ride, but why does it work???
The self centering effect does NOT depend on the seat and CoG height,
but on the negative trail and the angle of the steering pivot.
The P4 trike: There was some mention, that it could not go faster than
10-15km/h without beginning to wobble. Was that attitude "cured" by
lengthening it? Can it go at normal bike speeds (around 30km/h) now?
Yes, the longer wheelbase (+15cm) cured everything.
Jürgen.
