A snow vehicle basically includes a vehicle body, a saddle seat, at least one ski, an engine, a starter motor and a lithium power module. The engine is attached to the vehicle body. The starter motor is operatively coupled to the engine and electrically coupled to a first electrical connection. The lithium power module has a lithium battery with a second electrical connection that is configured to be toollessly connected and disconnected to the first electrical connection.

A drive device for a motorcycle is provided. The drive device includes an internal combustion engine having an adapter assembly arranged on a first end face of the internal combustion engine. The adapter assembly on a connection face opposite the first end face at least two connection geometries for different electrical drive units.

A hybrid vehicle includes: a crankcase having a main chamber formed in a case body and accommodating at least a crankshaft, an input shaft, an output shaft, and a gear train, the crankcase further having a subsidiary chamber formed between the case body and a cover and accommodating at least a main clutch; a rotary member disposed in the subsidiary chamber so as to be capable of power transmission to the input shaft; and a power transmission member that transmits drive power from a drive motor to the rotary member.

A crankcase includes: a main body portion aligned with a drive motor in a direction perpendicular to a motor drive shaft; and an extended portion continuous with the main body portion and located lateral to a motor housing, the extended portion receiving insertion of one end of the motor drive shaft. A power transmission mechanism that transmits power from the motor drive shaft to an input shaft is located partly in a first region defined by the main body portion and partly in a second region defined by the extended portion and communicating with the first region.

A hybrid vehicle includes: a crankcase extending from a lower portion of a cylinder of an engine, the crankcase including a main body portion defining a crank chamber in which a crankshaft of the engine is accommodated, the crankcase further including a breather portion projecting upwardly from the main body portion and defining a breather chamber into which blowby gas is introduced from the crank chamber; a breather tube that introduces the blowby gas from the breather chamber into the intake passage; and a drive motor disposed rearwardly of the cylinder and mounted on a top surface of the crankcase. The breather portion has a facing surface facing an outer peripheral surface of the drive motor. The facing surface of the breather portion is shaped to conform to the outer peripheral surface of the drive motor.

An electric drive motorcycle (100) is competed with a filter box in the rear portion thereof, without limiting the space available for the batteries, comprises: a front portion comprising one or more front wheels and a handlebar; a rear portion comprising a saddle (101), a shell body arranged below said saddle (101), and a rear wheel arranged below said shell body; an intermediate portion extending as a connection between said front portion and said rear portion; an electric drive unit (8) connected to said rear wheel (105); and a hybrid supply unit supplying said electric drive unit (8), comprising at least a battery unit (115) and a combustion engine (116) actuating an electric generator (120), said combustion engine(116) comprising an exhaust duct (133) with an expansion chamber (134) and a filter box (135) for feeding air to the combustion engine (116), wherein said electric generator (120) is apt to supply said battery unit (115) and/or said electric drive unit, wherein, inside the shell body (107) and below the saddle (101), a housing space is provided extending from one side to the other one of the shell body (107) and which receives the hybrid supply unit, in a first portion thereof, and wherein said filter box (135) and said exhaust duct (133) are arranged on the same side of the motorcycle.

A system includes a support arm. The system includes an engine supported by the support arm. The system includes an armature supported by the support arm. The system includes a coupling device disposed around the armature and slidable between a first position in which the coupling device couples the engine to the armature, and a second position in which the coupling device is uncoupled from the engine.
