A sectional electric drive vehicle includes a first motorcycle having a master electric control unit, a second motorcycle detachably connected to the first motorcycle in tandem by a connection mechanism and the second motorcycle including a slave electric control unit, and a system connector detachably connecting the master electric control unit and the slave electric control unit, to allow signals transmission between the master and slave electric control units. When the first and second motorcycles are combined and connected together via the connection mechanism and the system connector, the slave electric control unit relinquishes control to the master electric control unit, and the master electric control unit controls the cooperative motion of the first and second motorcycles. When the first and second motorcycles are detached, the first and second motorcycles are independently operable.
