Bonsoir Florent et bienvenue,

first let me say that the french translations of my site have been done by Thibault Ferron who was very generous. He even offered us an own python forum on his webspace instead of the mailinglist. But at that time we decided to stick with the list.

Second I agree with all the others: locking the pivot will lead to immediate disaster. Once Greg Kolodziejzyk from Canada (the 24 hours world record holder) proposed TWO pivots for the python. One with neg. trail for speeds up to 50 kph and another with positive trail for higher speeds. They can be locked alternately. This might work but seems far too complicated for me.

A friend of mine uses his python for 30 km daily commuting and he is very happy with it. In dense city traffic a lowracer can never be as agile as an upright bike. The riding is much more passive.

I am afraid, the python is not the best choice for your purposes.

Cheers,
Jürgen.

Hi all, first i present myself: my name is Florent
Balestrieri, I'm a 25 years old french guy, actually living
in Paris. I've got a very serious relationship with my bike
:))) which until now was upright. I'm NOW considering to
make a recumbant bike to ease my ass a little for the
journeys to come... :)

This decision was made after a long Internet session focused
on recumbents, wich ended on Jurgen's website. (by the way,
thank you VERY much for your dedication to this project and
your spirit of sharing and trying to improve your ideas. And
ALSO: i'm very impressed by your french version of the site
very helpful especially for the technical terminology. You
really mastered our language, i'm in awe).

Then followed a period of reading the mailing-list to
understand if the bike was really the one for me. The main
unsolved problem remains that damned speed limitation!!! i'm
a speed addict, riding mainly in the Alpes mountains where i
can enjoy the climbing uphills and flying downhills at mad
speeds.

If I recall well, max-speed is around 65 kmph. And people
reaching that speed confessed that their control on the bike
felt too light or odd or something.

My question is: has anybody ever thought of putting a lock on
the pivot before going downhill? Turning at high speed is
done by leaning anyway.
