It's a dualtron mini literally a premium scooter. i rode it for going nearby and school. it goes about 60km/h in flat road. it can climb the hill for example , i used to go kyungsung university with it. The charging backup is almost 28-32km. i changed both front and rear wheel tire recently (they are totally new). if you need more information, you will get huge from google about it. The reason for selling is, i bought a motorcycle.So i don't ride it now. you can come to my place , leave something and take it for test drive. Thank you.
