Hej Dirk,
Luka's first trial reminded a lot of his first time on an upright. He was very
eager but it will take some time!!
The bike is a little too big still and so is the seat. He says, the seat is
hard. The latter can be solved. The former will solve itself.
The front part is rather heavy. With a Sram 5 speed hub. Am I surprised?!
And the pivot made of brass bushes is pretty rigid. With his low weight, the
self centering is minimal.
Also the long rear part probably reduces the self centering. I wonder if I
simply cut it shorter.
And at the axis of the rear swing, or at the back wheel, I probably fix some
supporting wheels to each side. So I don't have to walk bended down next to the
bike, while Luka is doing his first exercises.
And the seat lean should be less inclined for him to reach the ground with his
hands. I just hesitated reducing the inclination, as the beginner is not
relaxed enough to go very recumbent. I seems now it would be better anyway...
What do you think?
About the seat: It was extremely easy to make and is very rigid and stable.
After assembling, I glued it with expoxy. I will definetly make one for my
python as well, where I still lack the proper seat solution. The wooden seat is
very easy to attach too. Because its construction can be adapted to the bike
structure. It seems the idea for the seat brought me a large step further,
while doing the final work on the bike. I strongly recommend it:

Hoi Thomas,
looks very nice. Did Luka try riding it yet? How well does the seat feel?
my greetings to your family,
Dirk
