    Front Derailleur folding bicycles

    I am trying to add front derailleurs to my 2 folding Downtube bikes, pictures attached. The problem is the seat tube angle means that they have to be set further back than normal in relation to the large chainring. I have clamps that fit and the necessary clearance for the 2 chainrings (22 & 42). I only need the largest 3 or 4 cogs with the 22 t chainring. Will it be a no go if the derailleur sets a bit behind the highpoint of the large Chainring? as long as I leave enough clearance? I considered using the forward tube on the mini but that set the cage too high to clear chain on small ring.

    your best bet is to just try it.
    Food for thought: if you aren't dead by 2050, you and your entire family will be within a few years from starvation. Now that is a cruel gift to leave for your offspring. ;)

    Very specialist question, I think you will get better & more appropriate on the Folding Bikes forum than here.
