Perhaps a stupid idea - but is there just too little weight on the
driven wheel?
Then of ocurse the best way to get more adhesion to the road may be
lower tyre pressure...
Just a thought.

Hi George,
With regard to frontal area I was comparing myself to MTB and Road
bike riders with those time trial style extensions on the front handle
bars that you rest your elbows on. When you look at them, front on,
their body is relatively horizontal, so its basically their shoulders
and legs. For me its my full torso, on about a 40° recline, plus the
rocker arm hardware below me and the rear wheels on either side of me.
To my eye, we all look about even. But obviously my trike has an edge ;)
On the issue of tire pressure, at 100psi on course bitumen the front
wheel does slip under acceleration, probably because as you point out
it is bouncing off the road surface. But for some reason tilting on
tight turns, harder tires scrub off speed. Its certainly noticeable,
but I don't know why for certain. The roads are I ride on are
generally very rough -- uneven from heavy vehicle traffic -- so I
assume that the hard tires on a lean are some how being repelled by
the road surface, or perhaps they are bouncing sideways so I am forced
to take a harder angle, thus scrubbing off speed. Either way the
softer tires definitely hold the speed better as my tilting trike in
corners. It seems about 65psi is a good compromise.
