Is there a spot for a good old-fashioned chain tensioner? You could always try a sturdy spring, arm and roller, drill some mounting holes and let the tensioner take up the slack for you.

Does your e-scooter use bicycle chain or a heavier grade? If the chain were comparable to bicycle chain i'd just use an old derailler with the cable removed for your tensioner.
