I find both Dirk's and Lennart's pythons more heavy-steered and sluggish than monty, but that could have other reasons than wheel

Ja, very complex everything. One major problem when comparing
different pythons is that once you are used to your own, every
other feels strange in the beginning and once you are used to
the other and change back to your own, this is the one that feels
strange now.

It is funny that after three years of experimenting with the
python geometry we still have no clue.

I have no computer on monty, but going downhill at around 40 kph I start imagining about ambulances, nurses and cruches. The bike feels
not safe. 

With 40 kph I would not feel save with any recumbent that only has
a front wheel coaster brake and no rear brake at all ...

Olaf, how much kilometers of riding experience you have with your
Monty? I am asking because riding skill is an important factor
when trying fast downhills.



I don't know, but not more than 1000 km. Reason for this small mileage is not disappointment with the bike but with the folding capacity which ultimately was monty's raison d'etre. For longer road trips I find monty less relaxing then my regular recumbent; you have to keep a sharp eye on the road, a deep pothole can be disastrous with 16" wheels, the front part is not straight and I believe this contributes to its nervous bahaviour at higher speed. But for meditave pleasure-cruising it beats my Hurricane, my Flevo, my mountainbikes and my five unicycles with a possible exception to the 36" Coker - that is also a cruising machine with nirvana qualities.



If you shorten the wheelbase more weight shifts to the front part 
Then why do people say that with longer wheelbase you get less wheel
slip? What piece of the puzzle have I lost?


My fault, it's as you say: Shorter WB brings less weight to the
front wheel, thus causing loss of traction.

Keep us in the loop Dennis, the Netherlands should be a perfect hunting ground for pythons ...
Ach, hilltops are so beautiful ...

Yeah, on my last tour to Karlsruhe, I learned to love the hills.


Did you try Hanno's Flevo? It would be interesting to know if these years riding the python has made it easier for you to master the Flevo. But like you wrote earlier in this post, experience from one bike is not always useful on another.

Or perhaps you did not dare to try the Flevo?
