Does anyone know of a cruiser type bike that has full/dual suspension? I can't find one, and I'm thinking I'll have to have it custom made.
Full Suspension Cruiser Frame?

I looked at those - in fact, if I have to fashion a frame, I might use the swing arm from an Avalon.
This might be the one you're talking about. (http://www.motoredbikes.com/showthread.php?24547-Dual-Suspension-66cc-Kent-Glendale-CS-Bike)
I have drawn a sketch using that swingarm with a Schwinn frame front end. I wish there were an easier way.

This is the one:

It's surfaced in my searches due to steel frame and full suspension.

You have to remember with dual suspension like that you have to figure out how to keep the chain tensioner properly.
Right - I read about that in the other thread, where he took out the rear suspension for that very reason.
I have to assume that the rear swingarm is steel...
Micargi has a bike like the rover that has a rear shock but I don't think it has front shocks. I'm not sure what it was called I cant remember.
The Cheetah. I remember seeing a build of one years ago, looked really good and with a long throw springed tensioner I don't think the axle movement would be a problem. Getting one might be though. Micargi dont show it on their site anymore. but this is possably one available. http://www.toplowrider.com/bikes/product_info.php?products_id=1574 Monarch springer yur all set.
Thanks, Velodrome! I went to the Micargi site and looked through all of their bikes and didn't see that one. I think it's out of production.
If the pivot point is in line with the center to center distance between sprockets then you won't need a tensioner as the chain slack will be minimum for our needs (+/- 2", 4" total travel This can all be calculated will simple trig functions.
Here is a quick xl spreadsheet calculation for chain slack for a rear suspension design where the pivot point is in line with the center to center distance between sprockets. It does not take into account sprocket sizes so may be slightly off, but not by much.
if you want to know how much it moves per two inch (approx) when it's not in line (fraction of an inch out) subtract the 4" from the 2" which is about .05". Compare to the .016" for the 2" movement here.
So yes, if your pivot is not in line you will need a tensioner. If it IS in line, you could get away without using one.

Here's one that I motorized from a company called Rusty Spokes... http://motorbicycling.com/showthread.php?t=49451
