I am still none the wiser, so I am out.
If you do not know what you want for it can I suggest an auction site maybe the way to go.
		
		
	 
I would suggest an 
off  the thread    PM might have been the way to go
FYI
I sold 2 finished Streetfox variants last year and got £400  and £425 
	
		
			
		
		
	
		
		
	
	
	
		
			
		
		
	
they were both ready to ride    ,
this was the £425 one
Fitted   with 24" wheels, 18 gears, Under Seat Steering   and straight boom these were going to be our holiday trikes before I built the 20/20 e-trikes The length was the reason I sold them as they would not fit in the boot of the mondeo with panniers
Unfortunately as a seller  you will never recuperate the reward for building one  as UK wages/rewards are much higher than china and if built in the UK would represent a price tag in excess of £3000 to make viable as an income . 
As a buyer you get something that was built with care in the UK that will last and be repairable unlike some imports !!!!
Down side for someone  buying the part built  is the strip, spray and refit that takes 2 x 1/2 days  and 2 days to spray  with rattle cans or £120 approx to have powder coated
Just my tupenny worth
