Abstract
The invention allows two single-seat bicycles to be connected to each other to be converted into a multi-seat bicycle. A fixed tube (), in the center of which a fixed shaft is inserted, is attached to a head tube () of a frame (). A top tube () supported by the fixed shaft is relatively pivotally installed on the head tube (). The fixed tube () and the top tube () can be connected and disconnected from each other by clutch means (). In the clutch means () are formed a pivot path for defining the un-clutched state and a closed path for defining the clutched state. The clutch means () is held at connected and disconnected positions by a position fixation member. Pivoting of the top tube () relative to the fixed tube () and the operation angle of a handle are limited by a synchronizer.
