I very much doubt that you made any conscious decision of how to turn
the handlebar in the first 1000km. The trick when riding a bicycle is
that you counteract a deviation from the desired course by turning the
handlebar in the "wrong" direction; e.g., if the bike veers left, but
you want to go straight, at first you turn the handlebar left; if the
bike goes straight, but you want to go right, at first you turn the
handlebar left.
That's normally totally subconscious, and when you consciously think
"steer to the right", your brain translates this subconsciously into
putting the appropriate forces on the handlebars, and, on upright
bicycles, to support this with appropriate upper body movements.
Learning to ride a normal recumbent (not a Flevo) is learning how to
do this with just the handlebars, and no upper body movements. I
learned this as adult and found it pretty easy. I have seen various
degrees of difficulties when other adults tried it; some could ride
easily right away, one had a really hard time. I guess it depends on
how much they do with the upper body normally, and how much with the
handlebars. Theory: people who are good at hands-free riding have a
harder time at recumbent riding.
