A forklift, comprising:

• a chassis;
• a first axle positioned on a first side of the chassis;
• a second axle positioned on a second side of the chassis;
• a fork assembly on the first side of the chassis;
• a first transmission system coupled to and configured to rotate the first axle;
• a second transmission system coupled to and configured to rotate the second axle;
• a gear transfer box coupled to the second axle, wherein the gear transfer box includes a torque amplification stage configured to increase a torque of the first axle;
• and
• a controller including at least one processor or memory configured to electronically communicate with the gear transfer box to raise or lower a torque of the first axle or the second axle based on one or more vehicle parameters.

A method, comprising:

• rotating, by an electric motor, a first axle and a second axle of a vehicle;
• sensing, by one or more sensors disposed on the vehicle, a characteristic including:
• a connection or disconnection status of the first axle or the second axle;
• a mechanical limit of a first transmission system coupled to the first axle or a second transmission system coupled to the second axle;
• or
• a resistance provided to the vehicle by surrounding terrain;
• adjusting, by a gear transfer box, a torque applied to the first axle or the second axle based on the characteristic;
• and
• lifting, by a fork system disposed adjacent to the first axle, an object.
