Where would we put the front pivot? When in line with the cassette there
will be a steering flaw under braking, when in line with the wheel (like
Mike Burrows' lowracer which had a non driven front wheel turning around
its hub) we'd have to put the chain line perpendicular to the plane of
the pivot. Which means an extra idler so we're back to the known FWDs.
So it seems to depend on how bad braking affects steering. Not so easy
to install brakes on such an offset front wheel either. Skipping the
front brake is not an option.
