PythonBike

Before



The Python is a center-steered lowracer with 2x26" wheels, front wheel drive..." (Juergen Mages)
The idea comes from Juergen Mages in Germany - The project and the history is in the link beside

After


I was planning to make a recumbent bike to use an old bike of my wife, but when I saw the site of Python I liked the idea. The fact that there is only one Python in Brazil and maybe 30 or 40 over the world ( I supose... ) turn the project into a challenge.
After 12 days I finished the work with 2 problems: Colision with te pedals ( solved), and the long distance BB-EOS that I need to solve.
In 06/08/2006, after 3 weeks I solved the problems and started the learning process...

Construction Pictures:





First problem:


Colision between new rear tube and pedals ! Second problem:

Due distance BB-EOS = 81 cm too much long, I will need to cut the tube moreless 10 cm to reach the pedals !!

Fiberglass seat


nal Tests...



Profile from Marc Huebner that I used like a model. Transport of points to a 1:1 scale Final profile comparing with Mr. Dirk Bonne seat



Starting the mould with two plates of wood.



Good result:



The Fiberglass seat is Great!!



Were 8 layers of fiberglass.



How to drive? I still don't known









# Dia time dist Details Obs.:

1 6/ago 30' 60 cm Maybe 10 times in my garage and only 60 cm without the hands in the floor... 1% of result... The Python is without gear shifter, I need to fix the brakes, to change the seat support, install cyclecomputer, etc...

2 13/ago 30' 60 cm Same training, same result, it's very hard. I Think that next time I need more space and the gear shifter to try how to ride with different gears Today the Python was without brakes, cyclecomputer, still without gear shifter and the seat must be finished...This week I will finished this tasks.

3 20/ago 50' 2 m Today the training was in a park, in a large place. The result was better. I run maybe 2 meters without the hands in the floor. I think the next time I will run more without the hands. The Python is the same that the last time. It has only the necessary to run.
