[python] Pivot bikes

Hi:

I've been going through the FWD SWB learning curve trying to design and
build a FWD SWB lowracer that meets the following criteria:

1. Low bottom bracket (so nose of fairing will be low)
2. Good turning radius
3. Solid handling at high speeds
4. gears, chain, etc does NOT interfere with leg movement 
5. crank does not interfere with front wheel
6. Efficient drive mechanism

It's NOT EASY! SO far, I have a FWD lowracer that score sort of OK on
most of these design points, but as far as I see it, the Python would
score 100% on ALL of these items.

Unfortunately, an initial version of my bike was a pivot bike and I
found it almost impossible to ride! Can you offer some comment on the
learning curve for center pivot lowracers such as Python?

Thanks,
Greg K
