[python] Python Bike/Trike

Hi,

I´m new in this mailing group. I´m not (yet) a python builder, but I like this 
concept - low, clean and a great improvement compared to the Flevo (I learned 
Flevo riding-basics 10 years ago in a long weekend but then decided to buy a 
more conventional Aeroproject "Sport Frame"...)in my opinion.

Now I think about recumbent bikes again (after a couple of years "upright", 
mostly riding only for fun and off-road), because I like to spent less time in 
my car and do the way to my work (30 km one way) more often with my bicycle. 
Like a lot of people I have problems with my back, my neck and my hands when 
riding in a "sporty", fast position on a convetional bike longer than half an 
hour. But I want to go fast! So I have a look on those very low recumbent 
(race-) bikes. Because of my budget (and because I really like to build/create 
something) I will build this bike by myself this winter. One of my favourite 
designs is the frontwheel-drive ZOX Z-frame. Easy to handle, fast and - easy to 
build. Even with some modifications (rear suspension, slightly on the 
geometrie). But when I found the Python in the net, I fell a bit in Love with 
its design. 

But I´m not sure, if it is, what I really need. I think I will loose speed, 
because of the need for steady corrections of direction. Pedaling and 
steering-work are done by the legs and I expect reduced pedaling-efficience. 
What´s your experience on the first 1000 km? How fast are you riding on flat 
bike paths? Where I live (Hannover), there are no hills, but rough surfaced 
roads and bike-paths, so downhill speed and -driveability are not really 
important.

Another thought: I found pictures of Jürgen Mages´ P4-Trike. Seems to be a VERY 
intersting concept for fast city-utility-use!? Jürgen, how does it handle? It 
has a crazy short wheelbase - can you really go straight ahead with it? Whats 
about high-speed stability?? Cornering stability? May be it is not the right 
vehicle for my "fast-to-job-bicycle-project", but a very interesting next 
project for city-use.

I´m looking for some input. Thanks for any ideas and advice!
