[python] Re: First test drive

Hi 25hz,

Traill:                     28
Seat height:            16
Ground Clearance:   7
Wheelbase:           132
Weight:                   14.5


thanks for translating the units into metric system.

I was also thinking of adding
handle bars to the sides of the front half of the bent to help me get the
hang of steering it.


Learning to ride the python is the hardest part. A lot of patience
is necessary, but this will be rewarded greatly.
I know that mostly all of you prefer handle bars, but I still think
that they do not really accelerate the learning process and you will
have another part that might be bent when falling.

I studied your design variations. The bike looks awesome, especially
the front part and the seat.
The weakness, that I spotted in the CrMo tube of the rear part,
already gave in. I wonder if you can notice a similar flexing as
Dirk http://dirkb.dnsalias.net/python.html
because with 32 x 1.6 mm (1 1/4" x .064") square tube for the
backbone you are quite close to his 30 x 1.5 mm square tube.

I appreciate that you want to make a motorbike-like stand. It weighs
about one pound, but it is really valuable. The included steering
stop eases the handling of the bike a lot.

The front wheel dropouts on top of the frame have the two benefits
of allowing lower seat height and improving the chainline. I have
the problem that in some gears the chain touches the chain stay -
you don´t.
Disadvantage of your solution is, that with a mounted front fender
or wheel well you cannot simply dismount the wheel for
maintenance. Maybe your half fender/leg guard is a solution.

Good luck further on, we are looking forward for your reports,
Jürgen.
