Still doing rough sketches of ideas for my Flavo (20/20) build. Not
going to have it separate at the pivot. Instead, maybe have the rear
swingarm fold up underneath the bike coming up alongside the front
wheel. Also have the seat and part of its rear brace `unlock' and fold
forward to sit flat above the main tube. Just as a Bike Friday is
designed. http://www.bikefriday.com/
Yet another geometry question. The FlavoFanClub site says the rough
plans of the 20/20 are of historical value only because of `technical
imperfections' and the bike has been completely changed. Side by side
pics of an 80s, 90s and 2000+ models don't seem to show any difference
in the basic frame geometry.
I ask because the plans show the steering pivot to be 45º. However
the geometry page on the Python site http://www.python-
lowracer.de/geometry.html says that a Flavobike's steering pivot is
40º. Is this what's changed or is Jürgen wrong? Asking those truly in
the know, which is correct on the latest model?

IMHO the pivot angle should be 70 degrees. The bike would then be easier to ride at low speed and can be started from a dead stop without using your hands. The...

I start my Racer no-hands. But at low speeds under high load (hill climbing), I find instability sets in at about 5mph/8kph. I think if I had the bodily...

Hi John, You are a better man than I. My Chinkara is a nice machine, but the low speed wobble is too great for me to start with no hands. A laid back head...
