Hi! I am selling my big eletric scooter with 72V Lithium ion batteries and Fapiao and Steellock for 1800 RMB. It handle 50km/h really easily and has a great range of 80km+. The Li-Ion batteries has been replaced this year (cost me 800RMB), so should be working smoothly. It's really heavy due to the batteries and you cannot take out the battery pack. The bike is in great condition, only the tachometer is somehow broken.
