Snowmobile

A snowmobile transmission assembly comprising:

• an input shaft;
• an output shaft;
• a first gear assembly, the first gear assembly including a first sprocket, a second sprocket, and a first belt extending around the first sprocket and the second sprocket;
• and
• a second gear assembly, the second gear assembly including a third sprocket, a fourth sprocket, and a second belt extending around the third sprocket and the fourth sprocket;
• and
• a selector operatively coupled to the input shaft to engage one of the first gear assembly or the second gear assembly, via one of the second sprocket, or the fourth sprocket,
• wherein the input shaft extends through the second sprocket, the selector, and the fourth sprocket, and
• wherein the output shaft extends through the first sprocket and the third sprocket.

A snowmobile comprising:

• a plurality of ground engaging members including an endless track positioned along a vertical centerline plane of the snowmobile, a left front ski, and a right front ski, the endless track being positioned rearward of the left front ski and the right front ski;
• a structural frame supported by the plurality of ground engaging members, the structural frame provides structural rigidity for the snowmobile, the structural frame including a tunnel:
• an electric powertrain operatively coupled to the endless track to power movement of the endless track, the electric powertrain comprising an electric motor operatively coupled to the endless track;
• and
• one or more battery assemblies operatively and removably coupled to the electric motor, the one or more battery assemblies being removably coupled to the structural frame, the one or more battery assemblies being configured for use as an external generator, when de-coupled from the structural frame and the electric motor.

A method of adjusting regenerative breaking for a snowmobile, the method comprising:

• receiving a first indication, the first indication corresponding to a speed of the snowmobile;
• receiving a second indication, the second indication corresponding to one or more of a pitch, yaw, or roll of the snowmobile;
• determining a regenerative torque multiplier, based on the first indication and the second indication;
• and
• adjusting a degree of regenerative breaking, automatically, based on the regenerative torque multiplier.

A method of disarming a snowmobile, the method comprising:

• receiving a preconfigured duration of time;
• determining that one or more types of user-input have not been received, for the preconfigured duration of time:
• disarming the snowmobile, automatically;
• receiving an indication corresponding to rearming the snowmobile;
• and
• rearming the snowmobile.

A method of swapping batteries, the method comprising:

• providing a vehicle comprising a plurality of ground engaging members, a structural frame, an electric powertrain, and a first battery assembly, the plurality of ground engaging members including an endless track positioned along a vertical centerline plane of the vehicle, a left front ski, and a right front ski, the electric powertrain being operatively coupled to the endless track to power movements of the endless track, the electric powertrain comprising an electric motor operatively coupled to the endless track, the first battery assembly being operatively and removably coupled to the electric motor, and the first battery assembly being removably coupled to the structural frame;
• determining a charge level of the first battery assembly is below a predetermined threshold:
• providing an indication corresponding to the charge level being below the predetermined threshold;
• and
• in response to providing the indication, receiving a second battery assembly in replacement of the first battery assembly.
