Retrofitting a Belt Drive to a moulton

I'm building up a moulton F Frame, and am considering fitting a belt drive on it, but I have zero experience of building them. As far as I can tell it should be straightforward - particularly as the moulton's rear fork has no seat stay, so no frame mods need to be made, however i have a few questions:
1. what sprocket fits the Sturmey Archer 3 speed hub, I know this can be done as I've seen the same sa hub with a gates belt drive being sold on LFGSS... http://www.lfgss.com/conversations/235963/
2. will the rear suspension mess with the belt tension? - the pivot is set back about 4 inches so in theory movement might slightly reduce the distance between the bb and rear axle...
3. How do I get hold of the belt drive?- is there a dealer / bike shop in London who can help me out? - or someone on LFGSS...

Belts need consistent and quite high tension - possibly & you'll need an expert here - to the point where it will compress the suspension and slacken itself off.

Save yourself the pain and use a chain?

Yes. You're probably right :(

Looks like those F frames have enough challenges as it is :)

the rest of the frame is actually pretty straightforward. Even after 52 yrs suspension and frame seems remarkably solid.

but i think belt drive might be a tad optimistic.

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

```

Just like Github, a blank line must precede a code block.

If you upload more than 5 files we will display all attachments as thumbnails.
