Thanks Torben and Rhisiart!

Today I made a new wooden seat which feels very promising! A few pics are
waiting to upload to the blog. Gonna have a test ride this evening.

There have been discussions in Finnish forum how to get over from the first
embarrassing meters which eat gloves very much, some use short sticks,
others wonder would it be reasonable to use stabilising side wheels or  use
roller skates (or similar) in hands.
I wonder how fast that kind of a training back end will be seen in Finland,

Anyways, I started my recumbenting in 2001 by doing a copy from Esko
Meriluoto's Hipparion trike which is also leg-steered.

one in bottom of the page.
Maybe it was a bit easier to learn python because of that, but still not
easy :)
