Hi all, Made some more decent pictures and shared them in a Picasa album again: https://plus.google.com/photos/115292543199069523585/albums/5877419428757741505?authkey=CK7Kp9yb07HK4QE I hope the pictures explain how the pivot works. It actually works well, but it seems not strong enough to last long. Will see. I presently ride the bike like an agitated orchestra conductor, waving around randomly with my arms, but its a lot of fun. Its really refreshing to learn something this basic at this age. I make steady progress each time I take out the bike, so its reassuring too. Any tips on riding are welcome. I did not mount a handlebar yet, so I learn hands free. A few questions: how much does the trail and wheel size influence the riding behaviour of the bike? Are bigger wheels better for riding stability? Has anybody tried to have the pivot behind the seat? I would imagine that pedal induced steering would be even less if the pivot was right behind the seat support point, so almost at the center of gravity and behind the rider hip joints. And one more: how about having a reversed python? That is, move the pivot back to the hind wheel and have it mirrored (at 115 degr (180-65) or having it at 65 degr. This would be a rear steered bike I know, but there are a few which work. Thanks, Tiha
