Rhysiart,
This proposal is sensible. Probably the really hard thing about
learning to ride a Python is having to acquire several new skills, and
unlearn several old skills about upright bikes, all at the same time.
Getting used to centre-steer before having to learn to balance the
Python may break up the experience into more manageable chunks. Is
there any chance of your borrowing a front-steering low racer, to
practice balancing without centre-steer?
Unless you plan to hurtle around corners at high speed, a tilting
mechanism may be more complication than it is worth. Does anyone know
anything about the tilting mechanism used in the Piaggio MP3? It is
described as using a parallelogram linkage to support two steering tubes
- the tubes (half-forks) are visible, but the parallelogram is hidden by
the bodywork.
On a non-tilting Pythonesque trike, see Esko Meriluoto's site: lots of
design detail and lots of information about his experiences with the
prototypes over a long period.
