Merci Laurent,i have my back close from rear wheel 3 or 4 cm ... no suspended fork but it's posible this short wheelbase make the bike nervous too
wheelbase: 114,5
isn´t this a little bit short for your size? I guess that you
are at least 185 cm tall.
There is no suspended fork , no stand, and a "p4 like" pivo... only the seet is a good light constrution in 5mm plywood and epoxy glueweight:13kg
Bravo, this is really a light one!
I realy want to understand why p1 can go faster than p3weight with pilot: 88kg, 51kg on front wheel, 37kg on rear
wheel mean cg 48cm back on front axle
I will get data from P1 and P3 as soon as possible.
next days i do some changes i think make pivo at 65° and coser as posible to the front wheelPivot Angle [°] : 69°
Trail: -30
until around 35/40 km/h after, the bike become to "nervous" and i can
stay on...at this "high" speed the quickness of reaction the bike have
is out of proportion with my quickness and my precision of my mouvment
to controle the bike... this is my feeling
Pivot angle is quite steep and negtive trail is long - this might make
the bike a little nervous. Maybe you feel a little difference with
a 20" rear wheel.
After all, you are very courageous, going that fast after two daysNot courageous, just because at "normal" speed i feel very good...
of training.
In general you are right: the python is an excellent bike for flat
terrain!
The more relaxed I feel, the easier I can let the bike roll
downhills.
Bon courage,
Jürgen.
