Drive train and systems for a three-wheeled vehicle

An apparatus, comprising:

• a frame of a vehicle defining a longitudinal centerline, the frame having an engine mounting portion configured to mount an engine assembly thereto;
• a swing arm having a first end portion rotatably coupled to the frame, and a second end portion rotatably coupled to a rear wheel assembly, the rear wheel assembly including a drive portion;
• and
• a reverse gear assembly coupled to the engine assembly, the reverse gear assembly including an input shaft including an input gear and an output shaft including an output gear and an output member, the input shaft configured to receive an input from the engine assembly such that the input gear rotates in a first direction, the output member being operatively coupled to the drive portion of the rear wheel assembly via a continuous linkage, the input gear configured to move relative to the output gear to transition the reverse gear assembly between a first configuration, in which the output gear is rotated in the first direction, and a second configuration, in which the output gear is rotated in a second direction opposite the first direction.

An apparatus, comprising:

• a housing configured to be coupled to an engine assembly of a vehicle;
• an input portion including an input gear disposed within the housing, the input portion operably coupled to the engine assembly such that rotation of an engine output member rotates the input gear, the input gear configured to be moved from a first position within the housing to a second position within the housing;
• an idler portion including an idler gear disposed in the housing and rotatably engaged with the input gear when the input gear is in its first position, the idler gear being spaced apart from the input gear when the input gear is in its second position;
• an output portion including an output gear rotatably coupled to the idler gear, the output gear being spaced apart from the input gear when the input gear is in its first position such that rotation of the input gear indirectly rotates the output gear in a first direction via the idler gear, the output gear being rotatably coupled to the input gear when the input gear is in its second position such that rotation of the input gear directly rotates the output gear in a second direction;
• and
• a sensor configured to produce a signal associated with an alignment position of the input gear.
