I sell two e-bikes. 1500/each. We bought them 3000 last year. They are in a very good state. They are both fast and allow you to ride as on a real bike.

They are not "diandongche", but still very nice to ride and faster than most of the small diandongche you can find.

I also give the locks for free - (real price 200 yuans each- and the battery chargers 200 yuans each also).

The batteries are ok and their autonomy is 30 km more or less depending if you pedal or not.

We live in Beixinqiao aera, near The Hutong for those who know where it is and are able to find it without a map :-)
