Coupling the motor with gears: a standard gear ratio can be used, to generate more rpm for the same amount of torque generated by the motor. But it is not advisable to keep more gears, as it would increase the load and reduce the rpm (which totally irony). This might led to drainage of more current also. Reducing the range of your vehicle.

Redefine max voltage you are giving to the motor: more advanced and heavy duty electric controllers can be installed to increase the controlled voltage provided to motor. But, when we provide more power to the motor, it starts to heat up fast. This can permanently damage the motor brushes and burn the winding coils. A internal fault can also occur. So there are limits there also.

Improve the cooling system: more speed is always directly proportional to more heat generation. So an effective cooling system is a must. The better the cooling system, better is the reliability. That effective is a cooling system. They would play a role, but might not that effectively at slower speeds.

Others: Others mean the plausible factors like weight, aerodynamics, wheel traction, effective weight distribution and others. They would play a role, but might not that effectively at slower speeds.
