Except gyros don't... stop. Sure, they require regular torque input to maintain constant angular velocity. However, they're typically constructed with all their considerable mass at the rim, so they have very high angular momentum. If power to the gyros fails for some reason, they will continue to spin, and continue to regulate balance, for quite some time. Certainly long enough to pull to the side of the road and deploy the kickstands.
It would be good engineering to tie some sort of gyro power failsafe into motive power and some sort of driver alert system, if it weren't even better engineering to just tie both of the "redundant" (I suspect that two horizontal gyros act to cancel any unwanted yaw torque that one would create by itself) gyros directly to accessory power. If the key is on, the gyros are either starting to spin or are spinning at normal speed. Like with any other vehicle, if you lose power at high speed, coast to a stop at the side of the road. At that point perhaps there is a non-powered mechanism to extend the kickstands?
