I have 2 26"Montague and Dahon Matrix
2 20" Dahon and Downtube
Mobiky 12.5
They are tools with specific uses.
You have to know where you want to ride
20+"are bulky but smooth
12"max I would go is a mile
EDIT added a Bromton 16". wIth it , nice if the roads are smooth, does not like rough or broken pavement. great fold..
and a Dahon Curve, with plump 16" tires, small frame size and not geared for hills, Better on coarser roads than the B , but small cockpit and only a 3 spd.
So, again, a lot depends on terrain you ride and have to cross with it folded.
