I have two of these for sale. They are sold as-is with no returns.

both are in used condition (about a year each) and are no longer in warranty. I will not accept any returns whatsoever.

Batteries are completely dead on both, but you can get parts and servicing from a Chinese company called Kysmo in Chinatown (on google maps). Google maps says the business is closed but it's wrong: the business is still open.

BTW, Kysmo sells these bikes for around $500.

A new battery is $150 from Kysmo. 

If you have a flair for fixing things electrical and want to save $70, I have one dead battery case and can tell you where and how to replace the battery cells yourself.  

I have an orange and matte black bike. The orange is in better shape, but Kysmo's batteries only come in black so the color will clash. 

This model comes with a lead acid battery and has a purported 20-mile range.

It's actually around 15 miles (pretty much all electric bike manufacturers inflate the range and speed of their bikes).

Foldable steel frame.

Pedal assist and full throttle power.

Wall charger and adapter.

45 pounds without battery.
62 pounds with battery.
