Without knowing the current draw of your motors, I cannot tell if any of our motor drivers are appropriate. However, I suspect your motors will draw more current than our drivers can source if they were used in a Segway.
One way you might try figuring out an approximate stall current of your motors is to measure the current draw while stalling the motor briefly at a very low voltage like 2V, assuming that the motor will start at a voltage that low. Since the current draw is proportional to the operating voltage, you could then multiply the measured stall current at 2V by 12 to get the approximate stall current at 24V.
If you post the approximate stall current, I can give you a better idea if any of our drivers might work for your system.
