The scooters were absolute garbage. Insanely slow and the back tire is no tire at all. It's a piece of rubber that is 16th of an inch thick. More over, they would not charge while they are off! So you plug it in and three minutes later, it turns itself off and does not charge. We were able to get one to fully charge by pairing the Bluetooth to a speaker and keeping music going, then it did reach a full battery, however, on the very next ride, the entire thing died and now no longer turns on. I would never recommend the scooter
