By the time you've finished cutting and welding you've essentially
fabricated a swing arm, even if your starting point was another
swing arm. I'd strongly suggest that you contact the guy with the
electric Riva to get whatever information, dimensions and
suggestions he has to offer.

If it were me, I'd probably stick with a single shock if the
original scoot had only one. If you go with two, that's
more mods to the scooter frame.
A good starting point would most likely be something
close to the layout and dimensions of the original
engine/transmission/swingarm unit. You might
have to go to a double arm to support a different
wheel, but all the way through, you should be trying
to minimize the layout changes you have to make.

I took a look at one of my three<yes three, count them> KE100s. The
swing arm is about as standard as you can get but the attachment is IMHO
one of those 'I wish I had thought of that' type designs. Basically a
folded sheet metal box welded to points on the frame. It has a tube
bushing/spacer inside to keep people from from crushing it and the swing
arm by over tightening the swing arm bolt.
It could probably be executed in a 'U bend with thicker metal which
seems simple enough. All of this is academic of course since we don't
know the dimensions of the motor/wheel. It could be the swing arm needs
to be two feet wide!
