I've had an electric skateboard for about a year now here in Shanghai. - Benchwheel
Small review here -
http://www.computersolutions.cn/blog/2015/09/benchwheel-electric-skateboard-review/
Replaced the battery already one time (about 10 months in).
Use it daily for to/from work +- 3km + some weekend trips of about 10km.
Great fun.
The "new" trend in Shanghai is scooters though. Almost same as a skateboard, but with a handle.
I would bring one back, but shipping lithium devices is a pain..
Guy at the office has a carbon fibre one that looks great, costs less than my board, and weighs less, but has more battery.
My skateboard cost 2799rmb last year, this year I'm tempted to upgrade to something with internal wheel motors as they roll faster - eg Stary or similar (the Stary is local, but a bit $$, there is a competitor Meibacc with dual motors and more battery for less)
I'll wait till mine breaks though.
