Hi everybody, I've been searching for other types of FWD trikes and found this:

Hello Jürgen,sadly the links to most of the p4 pictures that I found via the "search" function are defunct.The data I found were: wheel size 24" steering angle 66° seat height 25cm wheelbase 113cm (before lengthening??)As there is some serious interest in the p4 trike geometry, could you please bring back the gif or any more details?Would you say that the p4 in its final configuration is/was easy to ride? How much negative trail was there? How high the pivot? Sorry to bother you with questions... Yours Stefan Jürgen Mages schrieb: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.
