The base underneath is broken, but that's the only broken part. I haven't changed anything on the scooter except the rear tire, light, pedal, and seat. As for the pedal, I will buy a new one and give it to you with the scooter. As for the rest, I haven't changed anything since I bought it, like the battery, motor, wires, and other things. Price: 400 Problems: None Brand: The well-known Niazi Bought it a year ago.
