That will be no problem. As they say, I'll see what I can do.

I found the engine on another site (Right-click to open in new window):

In time:
I believe that the equipment uses the same principle of the attached image.
But the reducer of the excellent article (http://www.recumbents.com/wisil/tetz/e-assistmetric/ - John Tetz) is a mystery.
I have been researching on robust gearboxes for RC motors, with few results.
Can someone indicate some strong, 20:1, for a RC 50 mm?
I don't see anything fascinating about a kit that doesn't work.Lurkin said:Fascinating drive, pity there has been no change in the status on their website...

If you don't trust what was reported so far, get one and let us know your experience.tmho said:I also found very similar mid drive from taobao.com (https://item.taobao.com/item.htm?spm=a1z0d.6639537.1997196601.338.65e23eceVPXOdn&id=536287695596).
I guess GNG is just a dealer instead of the manufacturer. May be GNG cannot make the deal with the manufacturer and so they stop selling it.
I am also interested in it. But I would like to hear more reviews on it before buying. Hope those who own this will post more reviews on this mid drive. If anybody find the reviews from other sources, pls kindly inform me.
below are the specs.
Power: 280W , efficiency: 80%, around 15N.M at the bottom bracket. Motor RPM: 4800, reduction rate 1:30.
The motor can handle 280W continuous in 30degree Celsius without problem.
The kit is cadence-sensing.
When you pedal below few rpm the motor wont kick in, so shifting wont be a problem.
Right now we only have the chinese version of the BT app, but we hope to update it soon.
Now we have add another gearbox oil in the system so it is much quieter now. The unit keeps running 15000km now, and still holding strong.
We can supply parts if you have any parts need to repair.
