the practice on the trainer is fine, teachs you the movement, but not the coordination with reality.

I rode on my trainer all winter by clipping in and out. First time out on pavement (in a schoolyard; flat; no cars) i fell down almost instantly.

what i did (with a lady teaching me)
was I rode NOT CLIPPED in. THen I clipped in and out. She'd tell me to stop
and then I would unclip and then stop.

some people only do one foot at a time (two kinds of pedals) but if i can do it,
almost ANYONE can.
