My aim was somewhat different .
To make a folder that could be ridden in both the recumbent [down] and DF [up]
So that when touring and hitting steep stuff I could go into the up position
It needed to fold for Air trips
I took a Dahon {steel] [cheapest one I could find] and went to work.
After not getting it right a few times I now have it.
Made the seat and used old bits of rubbish bikes.
So with a quick flick of the seat forward and putting the seatpost up it changes from up to down and back
Worked so well I then put a Sram 3 hub with 8 and 2 out the front for 48 gears all up
Gear inches from 15 to 100
8000ks on it so far [Just back from a trip around Northern Ireland]
It is a bit heavy at 20ks
And would be nice to make one starting with something lighter
But I love my “Updown” bike
I haven't worked out how to put an Image on hear when I do I'll post a pic
