My granddaughter had a blast driving this around the house and in the field for 10 days, stopped for a drink and went to restart, as she tried to pull start the bike, the rear wheel started turning, luckily it didn't start, the only way to get it to start is to pick-up rear wheel, pull start bike and rear wheel starts spinning, as soon as it hits the ground it shuts off the motor.
it seems like the automatic transmission has locked up to straight power to the rear wheel.
