i have had no problems with my rigid frame however i am still learning to ride
it and have not been able to really test it.

Hi pythondrivers,
Birdcage has no suspension at all . On asphalt no problem. 4 bars
pressure in the tires (continental sport contact). Bumpy roads and
holes in the streets are problematic, especially for my head and
neck!
No much kilometres in 2010, hope it will be more on 2011.....

Hi all,
My Python have quite similar rear suspension as is in Jürgen's
bike. It softens the ride without being
too lively. I have used 20x30mm tubing (on it's flat side up) to
the rear and it's being on the limit, I'm 71kg and the tubing has
now some arc, mostly because I have been riding about 200 km with
a wooden block in a place
where should be a rubber block. I'm having a 1.9" tire in front
and liking it, have thought also some front suspension
because it's more effective that way.
But on the other hand, simplifying the building process is very
important to the first-time builders.
And here in Finland, most of Pythons are rigid, no issues on the
pavement.

I only ride on asphalt so the ride is fairly smooth. When
I go from the road into my driveway there is a bump. When
I hit the bump the frame flexes quite a bit. It scared me
at first. I think steel frames flex but on the python I'm
much more aware of it because I'm close to the ground and
I don't take up some of the bump with my bent knees.
I find the ride to be OK without the suspension.

Hello Rod,
it is not a bad idea to leave out the rear suspension.
Considering the
mount of effort, weight and the possibility of failure
it seems not
really worth to include a rear suspension.
So, I am thinking of revising my building side:
http://www.python-lowracer.de/construction.html
The goal is, to simplify the building process and to
save weight.
As I never rode unsuspended Pythons, I am curious to
hear some
experiences from you and other riders. Any cracks of
the rear frame yet?
Cheers,
Jürgen.
