The newer, metric version has a wheelbase range of 100-150cm, correspondingly
in the Imperial version.
Since almost anything is ridable with practice and attention, the idea is to
use the self-stable model as an indication of what is more easily ridable and
safe at speed. I was reading
http://ruina.tam.cornell.edu/research/topics/bicycle_mechanics/papers/bicycle_steering.pdf
yesterday, and skimming down toward the end there is some useful discussion of
response and oscillation frequencies; some which would be catastrophic on a
free-rolling bike are easily damped by hands/legs of a rider, others not.
