I would like some more info too :-)
For example:
-What happens when the front wheel slips. Is it as bad as with a Jetrike:
loosing control when cornering?
-How does the leaning actually work? I suppose the rubber is rather sturdy, so
you have to apply force (body lean) to lean the trike when not cycling. How
does this compare with high speed cornering? Except for the rubber, you would
also need to overcome the centrifugal force. (Currently, this compromise is not
optimal on my Pythonjetrike and high speed cornering does require more body
lean than I would like.)
-Any idea about optimal seat height - joint distance? Could it also be adjusted
by a different (stronger/weaker) rubber?
-Is the rubber also working as suspension and how much do you notice this when
hitting bumps?
-I know that those rubbers are not made for sideway forces. How do they hold up
over time? Any signs of cracks/wear?
Since I want to (re)build another trike, this might be a much easier and
cleaner design than the jetrike concept.
Thanks,
Patrick
