Hello, I have little idea about scooters, but I have an old Peugeot Ludix Snake standing around from an acquaintance and wondering if I can get it back in shape. After charging the battery, the scooter starts, but the oil lamp flashes in the instrument cluster. Is there something known here to fix the error? A short test drive showed that the scooter hardly comes from the spot, only with push I could drive a few meters, but the motor power was not enough to more al The scooter was standing around in the yard for at least 1 year in wind and weather. Can it be that the rear brake is jammed? How best to do this?
