Most people prefer to resemble Eddy Merckx;
rather than resembling a circus clown.

Indeed, many are too weak to resist peer pressure.

Or clever enough to realise what's better.

Yes, most are not clever enough to realize most have it wrong.



I think you do have it wrong.

For efficient cycling the upright bicycle is king. With an upright
bicycle the rider's feet are below his hips when he needs to lift
them. This is the most economical application of power to the cranks
and having the legs pendulus means the smallest effort is needed to
just turn the cranks. Having the legs horizontal totally messes up
this neat little system so that excuses are often raised about using
the seat-back because of the inefficient pedalling dynamics.

In our universe, aerodynamic drag is the greatest retarding force on a
bicycle, except at low speeds. In Trevor's universe, things may be
different.
