The  Schlumpf Drive shows that a geared BB is possible, but it only has
two  gears. As a resumee I would say that the "direct drive" is too
complicated  to be of practical value!.



It would take a bit of work, but why couldn't a multi speed hub be  driven by 
a pair of cranks instead of a sprocket?  I THINK that such an  arrangement 
has been done with a 3 speed and a kid's trike, but not totally  sure!  The 
onlyother way is vary wheel size!  My lean steer Trike  which is similar to a 
python in concept has a 7 speed cogset and a 3 speed  hub.  though I am going 
back 
to a straignt 7 speed t teh first  opportunity.  Not that the 3 x 7 doesn't 
work mind, it is going on  soemthing else, but I keep kicking the damned 
actuator with my right heel and  ankle!  afraid that I will break the hub, 
gouge my 
ankle or mess up my  tendons in my right leg from riding heel out all the time.

my youth, to outward appearance, by  mounting a bicycle for the first
time. The spectacles stayed on." -- Mark  Twain
