Your favorite Fnhon Gust has a very short wheelbase of only 900mm! Much shorter than a road bike, much shorter than the Brompton and Birdy who have almost the same wheelbase.

Its chainstay length of about 350mm is also very short.

Its a small bike designed for small people which is not a problem, this bike is designed for its main market. Same apply to many bikes designed mainly for the Japanese market like most Tyrell.
