Hi Pete,
Straight riding should be no problem ---Jürgen Maier already made such
a bike with rowing input (both using arms and legs).
But the trouble is that turning corners at lower speed requires a lot of
force input to overcome the self centering effect. This is easy using
legs (good leverage), but the force required to turn using arms only,
combined with the small leverage of handlebars is just too high. I have
handlebars on my python and they are only as an aid - for the fine
points as it were - the main steering force comes from the legs.
Like answered in other postings, I too would go for a modified rowing
bike.Your brother would be able to use his torso as an aid in riding .
The advantage would be two-fold: he'd be faster as the really strong
muscles are found in the torso, and he get good excercise in abdomen and
back (<- why I'd like a rowing bike for myself ;-) ).
