probably 2500--4000 RMB can buy a pretty nice one..under 2000 is not that reliable i guess.

i know, u mean e-bike, 1800~2500 yuan

I wouldn't pay more than 4000 Chinese yuan for an electric moped/scooter in Shanghai. If you want something cheaper, consider getting an electric bike instead (1500 used / 2000 new).
