Hi

For traction climbung hills it helps to have a low centre of gravity (low seat 
height).  With a low COG there is less weight transfer to the rear wheels on 
climbing a hill.

The next python trike I build will also allow the rear end to pivot about its 
length.  That way the rider can remain verticle on cambered roads.  My first 
python trike did not do this and I found it less than ideal on a cambered road.
