[python] Test ride

After spending some time last night fine-tuning the alignment, I test rode the
new bike this morning and I think that the pivot angle is just too small. The
front ends falls/turns rather easily side to side and the response to steer is
_very_ slow. I could not possibly turn the front fast enough to bring the bike
back under the center of gravity once it started going over. It would probably
be ridable at higher speed, but not starting out, or any low speed.
wheelbase: 131cm
pivot: 59.5
trail: 23cm
seat height: 27cm
BB height: 52cm

I attached handlebars to the seat tube, but they only helped a little and added
mass to the front end, which increases flop. (I clamped the old steel seat post
back into the cut-off tube upside down; the 1" handlebar stem fit inside the
post perfectly.)
I'll next increase the angle to ~64 degrees and shorten the wheelbase 1-2cm at
the same time. Trail will increase to ~25cm.
It is very comfortable, though :-)
