E200/E300: What if the chain keeps coming off my scooter?

  • Turn power off while working on the unit
  • Check chain tension, if chain is too loose/tight then it needs to be adjusted (refer to pg 6 in Owner’s Manual)
  • Make sure the sprocket on rear wheel is aligned properly with gear on motor shaft, if the rear wheel is out of alignment, it needs to be adjusted (refer to pg 7 in Owner’s Manual).
  • If the gear on the motor shaft is bent, then the motor needs to be replaced.
