2014. I was hesitant with this project as I suspected it may not work out due to its design. But it works, although there is a considerable pedal-steering interference. However, with a bit of practice it is rideable as can be seen in the last photo.  

It is very comfortable and fast to ride. Electric assist gives it an advantage of climbing steep hills.
It folds in a few seconds for storage and ease of transport. No removal of parts is required for folding.
It is adjustable for short and toll riders.
 26” front wheel with 15 gears.
12” rear wheel with 200W, 24V electric motor.
