A twitchy bike may be one where riding with no hands is difficult because any change in your leaning will make the bike quickly turn - usually a straight fork and a tight geometry. A dead bike is one you could ride all day with no hands and even make gentle turns by shifting body weight. It is slow to respond to acceleration, turns and just about everything else, like my old Schwinn Varsity. A twitchy bike is my racing bike - a Fondriest.
