For a brushed motor, that would be a good way to get home if the controller blows. But for routine use, it's probably not a great idea to tap your bank like that. The battery discharge will be different from one batt in the bank to another. I actually considered using a brushed motor just because I could in an emergency power the motor directly from the batteries, but decided instead to keep a spare controller. (and a spare motor, too!) I would MUCH prefer, if using a brushed motor, to have proper PWM speed control of the motor, at least for the primary means of powering the motor.
Better than simply tapping the bank, consider paralleling the bank so you get full use of all batteries at 24v, and at 12v. Could be done with relays, or manual connections in a pinch. Just be aware that line losses can be astronomical at the 12v level.
